Eeltail catfish
Striped coral catfish ( Plotosus lineatus )
The coral catfish ( Plotosidae ) Family (size: plotos = fluent) or Aalwelse consist of about 40 species in nine genera that live in reefs and adjacent brackish and fresh waters in the Indian Ocean and West Pacific to the Fiji Islands. More than half of the species lives in fresh waters of Australia and New Guinea.
Features
The fish have an elongated body with an eel-like, pointed or rounded tail, which is surrounded by a Flossensaum from zusammgewachsener second dorsal, caudal and anal fin. The caudal fin is pointed or rounded. The first dorsal fin is short and has a sting. The genus Plotosus and some others have venom glands in their spines in the dorsal and the ventral fins, which have caused fatal injuries. An adipose fin is missing. The head is relatively small for catfish, the teeth are conical. In the lower jaw there are also back tooth-like teeth. The gill membranes are not fused together. The number of Branchiostegalstrahlen is seven to 14 with their most four pairs of barbels seek their food on the ground. The swim bladder is boneless capsule.
The only known from a source of fresh water in South Australia Neosilurus gloveri is 8.4 inches, the smallest kind, the largest species Plotosus Canius reached 1.5 meters and lives on the shores of India to New Guinea, both in the sea and in the lower reaches of the rivers. Large species are fished commercially. An attempt is made to breed them in aquaculture.
Reproduction
Freshwater species operate brood care and build nests in the gravel base. Marine species spawn hidden. Your boys form dense spherical swarms "roll" across the floor. Thus, the individual animals for a predator can not be identified and protected.
