Very cool work from the Teleost zoo! #TeleostTalk 🧪

Xiphophorus fish are one of the oldest animal models for cancer research (dating back to 1920s). It provided the first evidence that cancer has a genetic basis after it was found hybrids of platyfish (X. maculatus) & swordtails (X. hellerii) can develop highly malignant melanomas. #TeleostTalk 🧪

Toughest fish on Earth? Mummichogs are a euryhaline species, which means they can survive a range of salinities from freshwater to water that has 110g salt/L. Heralded as the first fish species in outer space, they even evolved resistance to toxic chemicals that would kill other fish. #TeleostTalk 🧪

Fun facts about #pupfish: Actually a kind of #killifish, they get their names from their active and playful lifestyles. But don't let the name fool you, they are famous extremophiles and can withstand lethally high water temperatures, high salinities, and extremely low oxygen levels. #TeleostTalk 🧪

The African turquoise killifish (Nothobranchius furzeri) is known as one of the fastest ageing vertebrates. It reaches sexual maturity after 14 days post hatching and has an average lifespan of 4-9 months. For more on this model organism, read pmc.ncbi.nlm.nih.gov/articles/PMC... #TeleostTalk 🧪

To infinity and beyond! Japanese rice fish (Oryzias latipes) were the first vertebrate species to mate in orbit on board the space shuttle Columbia in 1994. Physiological research continues on board the International Space Station within the Aquatic Habitat module. #TeleostTalk 🧪

Celestial Pearl Danio (Danio margaritatus) became an instant hit on the aquarium trade for its vibrant color. Commonly referred to as the Galaxy rasbora, Myanmar banned exports of the fish in 2007 due to its popularity. Now, the fish is captive-bred for hobbyists. #TeleostTalk 🧪

Very cool analysis on Paradise fish (Macropodus opercularis) by @nickarjones.bsky.social et al. 🐠 #TeleostTalk

White-blooded Antarctic icefishes are unique among vertebrates because they lack functional hemoglobin genes. Their blood transports ~10% as much oxygen as the blood in other teleosts, making them sensitive to hypoxia and an excellent model for human blood disorders. #TeleostTalk 🧪

A. mexicanus are a promising model to study nutritional control of development as cavefish larvae yolks are larger & appear more yellow compared to surface fish suggesting differences in nutritional content. Reciprocal crosses show how maternally-provided nutrients impact development. #TeleostTalk 🧪
