Ordem Cyprinodontiformes
Os peixes da ordem Cyprinodontiformes possuem uma única nadadeira dorsal, a nadadeia anal raramente possui espinhos e presença de escamas ciclóides no corpo. O corpo é fusiforme, geralmente pequeno, não excedendo 30 cm nas grandes espécies, mas alcançando 8 cm na maioria. Não existe nadadeira adiposa, nem linha lateral e a boca é usualmente grande e superior.
Simpsonichthys constanciaeO grupo ocorre predominantemente em águas doces tropicais (exceto Austrália e Nova Guiné), mas muitas espécies são encontradas nos estuários e/ou áreas da região temperada da América do Norte, planícies costeiras mediterrâneas e no mar Negro. As aproximadamente 850 espécies conhecidas sendo distribuídas em 9 famílias e duas sub-ordens dentro dessa ordem.
A ordem Cyprinodontiformes é dividida conforme abaixo (Segue algumas fotos das espécies pertencentes a essas subordens e famílias) :

New Year's Pet Safety Tip
It's almost time to celebrate the start of a new year. Hopefully things will be better in the new year then they were around the world in this one. With celebrations also come tips on how to make sure your pets are safe this coming new year's eve.
Balloons and confetti are fun party decorations, but they can cause your pets to choke or obstruct their intestines if ingested. Keep an eye on your pets when they're around these items or move them to an area that is not decorated.
New Year's is typically a noisy holiday. Unfortunately, loud noises frighten some pets and can cause them to react in ways that are uncharacteristic for your furry friend. They might run off, bark more often, and act defensive by biting or attacking people and other pets. Even the friendliest pet can show signs of aggression and violence when they are spooked by loud noises. Keep your pets in a separate room, away from noisemakers, music, and other loud sounds that may startle them.
Also, watch out for other common holiday decorations such at plants, Christmas tree water, decoration hooks, Styrofoam, ornaments, and tinsel. All can cause problems if chewed on or swallowed by your pets.
Happy and safe new year to you and your pets!!

Canines Battle Bed Bugs
Canines Battle Bed Bugs in New Business Venture
Bed Bug Finders, LLC announces the launch of a new business serving Connecticut, Massachusetts and New York. It's a business that was created to help homeowners and businesses deal with the ever-growing bed bug population in North America.
The detects bed bugs by using highly-trained dogs. They are quickly
able to seek out these difficult to find pests.
Bed Bug Finders, LLC is only a bed-bug detection company; it is not an extermination company. The company will work with any extermination company to remediate bed bugs by identifying their exact location.
The dogs find the exact site of the specific infestation within minutes.
This saves customers a significant amount of time and money. For instance, dogs can search the average hotel room in less than two minutes. Many times the solution is fast and easy and may simply call for throwing out an old clock radio or book to resolve the problem.
The company's approach is to perform a "search and destroy" process and not a "spray and pray" approach when it comes to the detection and remediation of bed bugs.
The members of the canine team are more than 96 percent accurate when it comes to locating bed bug infestations. Often, the company will use two canine members to verify the infestation making its accuracy nearly 100 percent.

Nova espécie de Knodus
Uma nova espécie do gênero Knodus é descrita nos arredores do rio Maranon em Iquitos, no Peru. O mesmo durante cerca de 40 anos foi erroneamente distribuido ao comércio aquarístico com o nome de Boehlkea fredcochui (Géry, 1966). Descrito pelo ictiólogo alemão Axel Zarske, a nova espécie foi nomeada de Knodus borki.
Knodus borki distingue-se de Boehlkea fredcochui pela dentição do osso maxilar (três a quatro dentes tricuspides versus 11 a 21 dentes tricuspides), linha lateral incompleta (com 6 a 14 escamas) versus linha lateral completa (com as 15 a 37 escamas), e tambem na coloração (B. fredcochui apresenta uma barra negra na nadadeira caudal e esta é ausente em K. borbi).Knodus borki é estreitamente relacionado a K. megalops, mas difere na linha lateral (incompleta em k. borki versus completa em K. megalops), no tamanho do olho (2.46-3.24 vezes do comprimento padrão em K. borki versus 2.2 em K. megalops), na altura do corpo a frente da nadadeira dorsal (2.91-3.34 vezes do comprimento padrão em K. borki versus 2.9 em K. megalops), no comprimento principal (3.94-4.65 vezes do comprimento padrão em K. borki 3.8 em K. megalops) e na coloração.
Borki se refere a Herrn Dieter Bork, um grande amigo aquarista que contribuiu ao desenvolvimento do hobby.
No artigo também é redescrita a espécie Boehlkea fredcochui.

Poll - Pet Owners Not Cutting Back
According to results published in a recent Petside Poll, a majority of those surveyed say they are not cutting back on expenses when it comes to their pets.
Of those surveyed, 85% say they are not cutting back due to economic pressures, even as most surveys are showing that consumers are cutting their expenses overall.
Predictably, lower-income pet owners are twice as likely to have had to make cuts as higher-income owners (11% vs. 20%).
Among the 15 percent reducing pet-related expenditures, cutbacks can be drastic. Half (54%) stated that they are deferring routine visits to the veterinarian, while one in five (21%) are also putting off vet visits for serious problems. One in four (27%) are even considering giving up their pet due to financial difficulties.
The most common cutback is buying fewer toys and clothes for their pets, followed by switching to a cheaper type of food. This can be a tough thing to do for many, as cheaper pet foods mean cheaper quality, and could lead to an unhealthy pet in the long run.
Nevertheless, in spite of the economy a good number of pet owners plan to include their pet in holiday festivities this year. 43 percent of animal owners plan on purchasing a gift for their pet this season. Canines also have an edge over the felines when it comes to owners expecting to buy a holiday present for their pet (48% vs. 28%).

Poll - Pet Owners "Talk" To Pets
The Associated Press and Petside.com just released a poll taking a look at the relationship between pets and their owners. Topics range from lighter matters -- like whether or not people think they fully understand what their pet says -- to a serious investigation into the impact of the economy on pet care.
According to the Poll, 67% of those asked say they can comprehend their pet's own language. 62% say their pets understand what they are being told.
Dog owners were most likely to say that their pet understands them as compared to cat owners (though cats are sneaky!).

Endangered Turtles Arrive in CT Aquarium
Mystic Aquarium & Institute for Exploration, divisions of Sea Research Foundation, Inc., is now home to four sea turtles – Charlotte, a juvenile green sea turtle, and three loggerhead sea turtle hatchlings. Their arrival marks the first time in more than three years that the Aquarium has had sea turtles on exhibit.
“All seven species of sea turtles are either endangered or threatened,” said Don Harrington, interim director of Fish & Invertebrates at Mystic Aquarium & Institute for Exploration. “The turtles’ arrival here has given us the invaluable opportunity to educate our visitors about the plight of sea turtles and how they can help these wonderful creatures.”
Charlotte came from the Georgia Sea Turtle Center on Jekyll Island , Ga. , on November 23. She was found stranded on Cumberland Island , Ga. , and taken to the center last January. Her shell and hind flippers were covered with barnacles, and she had been struck by a boat’s propeller. A CT scan and MRI revealed a fracture or break in her vertebrae and a compressed spinal cord, which partially paralyzed her intestinal tract and hind flippers. The paralysis prevents normal movement of her gastrointestinal tract, causing gas to accumulate, which makes it difficult for her to dive. As a result, she floats with her rear end up.
Though Charlotte has been deemed non-releasable, there is a chance that, with long-term rehabilitation, she could recover and possibly be released back into the ocean in future years. Until then, she is serving as an ambassador for her species while staying in “ Stingray Bay ” on the main exhibit floor. Charlotte is the first sea turtle the Georgia Sea Turtle Center has placed in an aquarium.
“It could take years for Charlotte to regain specific biological functions needed for release back into the wild. We needed to find her a home, so that we can continue to take in more injured turtles,” said Dr. Terry Norton, D.V.M., veterinarian and director of the Georgia Sea Turtle Center. “Mystic Aquarium & Institute for Exploration was a good fit for Charlotte . We knew the aquarium would provide her with a good quality of life and would use her story to spread awareness of how common boat strikes are.”
The three loggerhead hatchlings arrived on October 28 from the North Carolina Aquarium at Pine Knoll Shores . One was rescued from its nest three days after hatching after showing signs of sluggishness. Another was found on a beach with a flipper injury, and the third was rescued from its nest before Tropical Storm Hanna arrived. The abnormally high tides created by the storm would have flooded the nest.
The loggerheads will be raised here until they are ready for release into North Carolina ’s waters in one to three years. In the meantime, visitors can see them in a new exhibit on the Aquarium’s main exhibit floor, opening tomorrow.

SEA TURTLE FACT SHEET
Green Sea Turtles
Green sea turtles get their name from the color of their body fat, which is green from the algae and sea grass they eat. Their shells are usually dark brown in color and heart-shaped.
Males and females look the same until they mature, when males’ tails grow longer and thicker.
The green sea turtle is the slowest growing sea turtle, taking up to 40 years to mature.
The largest hard-shelled sea turtles, they can weigh up to 500 pounds and have shell lengths of up to four feet.
Loggerhead Sea Turtles
Loggerheads get their name from their large head size. Humans’ heads would have a diameter of three feet if it were the same proportion as a loggerhead’s.
They are primarily reddish-brown in color. Males have narrower shells and longer and thicker tails than females.
Full-grown loggerheads are between two and a half and four feet and weigh 170 to 350 pounds on average.

Outdoor Pet Hazards
When your pets are outside, remember that there are plenty of outdoors objects and chemicals that are harmful to your pets. Here is a list of the most common ones from the ASPCA.
*Algae (can be found in ponds or other bodies of water. Certain forms may be hazardous).
*Antifreeze/Coolant
*Fences or gates. Pets can run away if fences are old and they find an opening. Pets can also get stuck in those openings and possibly get wounded or even strangled.
*Deck Lattice - Same as for fences
*De-icing salts. Some formulas may contain chemicals that are hazardous to pets if ingested. Wipe your pets paws after going for walks in areas where there might be salts. Also, look for pet-friendly brands for your home.
*Compost, particularly if moldy.
*Oil
*Pesticides
*Fertilizers
*Swimming pools and hot tubs. Never leave your pet unattended near uncovered pools, even if they can swim.

Christmas Hazards for Pets
Christmas is almost here, but be sure to take precautions with your pets. And if you are taking your pets with you to visit relatives, make sure to look for potential hazards at their homes as well. Here are some of the common things to watch out for during the holidays.
- Holiday plants. Christmas rose, holly, lilies and mistletoe are all toxic
- Ribbons. Placing one around your pets neck for "decoration" could cause them to choke
- Fire salts. Contain chemicals that are harmful to pets
- Spun glass (angel hair). Can be irritating to eyes and skin, and could cause intestinal obstruction if eaten in large amounts
- Christmas tree water. Stagnant tree water or water containing tree preservatives could result in stomach upset if ingested.
- Decoration Hooks. Can cause blockage and/or trauma to gastrointestinal tract if swallowed.
- Styrofoam. Can cause your pet to choke if swallowed.
- Ornaments. They may look like little toys to cats and dogs. Unfortunately, they can cause serious injury, especially if your pets break or swallow them.
- Tinsel. Can cause choking or internal trauma if swallowed.
Enjoy a safe and happy holiday season!

Descoberta de novas espécimes de peixes em Brasília
Biólogos da UnB descobrem 12 espécies em córregos do Parque Nacional de Brasília
A apenas 15 minutos do centro do Distrito Federal, o Parque Nacional de Brasília abriga as mais novas espécies de peixes do cerrado brasileiro registradas pela ciência. A descoberta foi feita pelo biólogo Pedro de Aquino e sua equipe da Universidade de Brasília (UnB), que estudou as espécies do parque durante dois anos para a dissertação de mestrado. Em riachos das bacias de Santa Maria Torto e Bananal, Aquino identificou, ao todo, 28 espécies de peixes, das quais 12 novas para a ciência.
Entre as 12 novas espécies identificadas no estudo, o Astyanax sp. (à esquerda) é aquela que teve o segundo maior número de exemplares coletados. Essa espécie é encontrada em todos os trechos dos riachos que deságuam no lago Paranoá, assim como o Hasemania sp. (à direita), que é 1 cm menor que o Astyanax sp. (fotos: Pedro De Podestà Uchôa de Aquino).
Esta é uma das novas espécies que nada desde a cabeceira até a foz dos riachos. Aquino explica que isso foi possível graças ao tamanho desse peixe: “Por atingir um maior porte, o Astyanax sp. é capaz de se deslocar com mais facilidade e, por isso, pode ser visto em todos os trechos. Já as espécies com pequeno porte ficam isoladas nos diversos trechos da bacia”.
Segundo o biólogo, o isolamento dessas pequenas populações nas cabeceiras permitiu que elas se diferenciassem até configurar novas espécies, com o passar de milhares de anos – fenômeno que os biólogos chamam de especiação alopátrica ou geográfica.
Parque Nacional de Brasília
Por isso, Aquino destaca a importância da preservação do Parque Nacional para as espécies nativas da região, longe da poluição e do crescimento urbano. “A preservação é fundamental para a manutenção da biodiversidade do cerrado. Se essa região não fosse conservada, talvez as espécies não seriam encontradas, já que o Parque Nacional fica dentro do Distrito Federal”, enfatiza o biólogo.
Fonte: Ciência Hoje
O objetivo da pesquisa era analisar os diferentes padrões de distribuição dos cardumes nas bacias do Parque Nacional de Brasília, unidade de conservação de proteção integral do Distrito Federal que fornece água potável à capital. A descoberta das espécies acabou sendo uma “cereja sobre o bolo” que enriqueceu ainda mais o estudo.
Microlepidogaster sp. Uma das novas espécies encontradas em Brasília, é conhecido como “cascudo” e pertence à família Loricariidae
Mas a descoberta não é surpreendente, na avaliação do biólogo. Segundo ele, a imensa variedade de flora e fauna do parque contribui para a realização das pesquisas. “Já esperávamos encontrar novas espécies, porque os cardumes ainda são pouco estudados, apesar da riqueza da região”, reconhece.
Aquino conta que escolheu 14 pontos diferentes ao longo dos córregos para a pesquisa, realizada simultaneamente com a da bióloga Mariana Schneider, que coletou os peixes para análise de seus hábitos alimentares. Os resultados do trabalho foram submetidos para publicação em periódicos especializados e aguardam avaliação.
Espécies endêmicas
Duas das 12 novas espécies identificadas no estudo – Heptapterus sp. e Ctenobrycon sp. – são consideradas endêmicas do Parque Nacional. As outras dez foram encontradas em outros trechos da bacia fora do território delimitado para o parque brasiliense.
A espécie que apresentou o maior número de peixes coletados no estudo, com quase 6.000 indivíduos, foi a Knodus moenkhausii, que já havia sido descrita pela ciência. Em segundo lugar ficou a nova Astyanax sp., com quase dez vezes menos espécimes coletados.

Nova espécie de Apistogramma
Uma nova espécie do gênero Apistogramma é descrita para as drenagens do baixo Mamoré na província de Beni na Bolívia. Descrita pelos ictiólogos alemães Wolfgang Staeck and Ingo Schindler, a nova espécie foi nomeada de Apistogramma erythrura.
Apistogramma erythrura é relacionado com Apistogramma trifasciata, pois ambas as espécies possuem a nadadeira dorsal altamente prolongada na parte dianteira nos machos, uma nadadeira caudal redonda, uma faixa lateral larga que se estende até a cauda, sem um ponto caudal.
Apistogramma erythrura pode ser reconhecido e separado de Apistogramma trifasciata pelas seguintes características:
Forma do corpo: corpo mais profundo (mais alto na parte traseira) em relação a A. trifasciata, fazendo Apistogramma erythrura parecer maior, embora ambos apresentem o mesmo comprimento.
Faixa lateral: a faixa lateral de Apistogramma erythrura é mais larga do que A. trifasciata, pois ela alarga-se na base da cauda. Tal faixa é mais distinta na metade traseira dos peixes e é frequentemente pálida ou nao visível do corpo até o opérculo.
Opérculo: Em muitos machos do Apistogramma erythrura, a parte posterior mais baixa do do opérculo mostra uma mancha vermelha brilhante. Ja em Apistogramma trifasciata, nenhuma população foi encontrada com tal características.
Marcações abdominais: Apistogramma erythrura não possui a listra diagonal escura que estende das nadadeiras peitorais ao ânus, muito evidente em Apistogramma trifasciata.
A nadadeia caudal do macho pode ser vermelha ou azul ou mesmo uma combinação das duas cores.
Erythrura tem origem do grego, onde erythro significa vermelho e ura significa cauda, uma referência a cor da nadadeira caudal na maioria dos machos adultos.
De acordo com os autores, Apistogramma erythrura é encontrado quase exclusivamente nos lagos, ou em áreas mais lentas de córregos. Vivem em águas límpidas e transparentes, com pH em torno de 5,5 a 6.5 e temperaturas de 30ºC.

É mais encontrado abundantemente em locais com muitas plantas aquáticas como Eichhhornia azurea misturadas com Paspalum repens, Cabomba furcata ou Utricularia spp. Quando em perigo saltam da água e frequentemente encontram-se imóvel por dez ou vinte segundos na superfície das folhas da vegetação emersa.
Sua alimentação na natureza consite de copepodas, ácaros e larvas de inseto diferentes. O mesmo possui distribuição tanto na Bolívia quanto no Brasil.
