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 🧪

Fig. 6. The Mexican tetra, Astyanax mexicanus, as a model to study nutritional control of development. This species of small fish (~4–6 cm as adults) consists of cave-dwelling morphotypes (cavefish, A, C) and ancestral river-dwelling morphotypes (surface fish, B, D). Cavefish evolved from surface fish in perpetually dark caves and adapted to a nutrient poor diet of bat guano and material brought in by seasonal floods. The fish are easy to maintain in the laboratory and are interfertile. Cavefish larvae (C, 4 days post fertilization (dpf)) have more yolk and the yolk appears more yellow compared to surface fish (C, 4dpf) suggesting a difference in nutritional content. The yolk of F1 surface cave/hybrids produced from cavefish females (E) is more yellow compared to those produced from surface fish females (F). Comparing these reciprocal crosses will be useful for understanding how maternally provided nutrients in the yolk impact development. Scale bars = 0.5mm.

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 🧪

The blackfin icefish, Chaenocephalus aceratus, lacks hemoglobin and lives in Antarctic waters, where the temperature is often close to the freezing point of seawater. Text credit to New York Times. Image credit to Doug Allan/Nature Picture Library, via Minden Pictures.
