Description
The Aral stickleback is a small, slender fish of the family Gasterosteidae reaching about 6 cm. In front of the soft dorsal fin stands a row of separate, short spines, the hallmark of the nine-spined sticklebacks; the grey-brown body is often mottled. The species lives in fresh and brackish water of the Ponto-Caspian region, around the Black Sea, the Sea of Azov, the Caspian Sea and the Aral Sea, in slow-flowing rivers, pools and lagoons. It eats small zooplankton, insect larvae and worms. In the breeding season the male turns dark, defends a territory and builds a nest of plant material, in which it guards the eggs and young. The species tolerates strongly varying salinities.
