Description
The Atlantic sturgeon is a large, anadromous fish with an elongate body that bears five rows of bony plates instead of scales. Beneath its pointed snout are four barbels and a downward-pointing, protrusible mouth used to search the bottom for prey. It feeds on benthic animals such as worms, molluscs and crustaceans. Adults live on the continental shelf and in estuaries and ascend rivers to spawn. The species can become very old and, at over four metres, exceptionally large. Owing to overfishing it is assessed as Vulnerable (VU).
