Blenny darter Blenny darter The blenny darter ("Etheostoma blennius") is a poorly known species of fish in the family Percidae, from Alabama and Tennessee that inhabits swift riffles. The blenny darter lives a maximum of two to three years, grows to a maximum of 69 mm standard length, and is sexually mature at one year. It is reproductively active throughout March and April. Spawning occurs over gravel riffles with swift currents. Mature eggs are orange and translucent. The fish are insectivorous, with analyzed gut contents containing Nematocera larvae, more specifically black fly (Simuliidae) and midge (Chironomidae) larvae. Significant numbers of mayfly (Ephemeroptera)
Leaping blenny a maximum water depth of 2 metres. They inhabit holes in limestone deposits in intertidal zones, and leap between holes when disturbed, earning them their common name. They are very social at mid-tide, using visual displays to warn off competitors and attract mates. Although they must remain moist to breathe, the blennies are able to breathe air, and avoid submersion by tide waters. Leaping blennies feed primarily off of algae. They are oviparous and form distinct pairs when mating. They can reach a maximum total length of 10 centimetres (4 inches). Leaping blenny The leaping blenny ("Alticus saliens"), also known
