जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Inhabit fresh to hyper-saline waters (to 55 ppt) of lakes, estuaries and lagoons, in shallow areas with much weed. Feed on small crustaceans and chironomid larvae (Ref.12215); larvae of the mussel Dreissena polymorpha (Ref. 59043). Lives less than 2 years. Spawns after first winter. Eggs are attached to the roof of a cavity under stones, plant material or shells and are defended by male. Postlarvae are pelagic. (Ref.59043).
