The earmark tube eel ( Heteroconger hassi ) is a saltwater fish. It belongs to the conger eel family (Congridae) and is a species from the order of the eel-like (Anguilliformes).
Scientific name
In 1959, which was latticed-pipe eel by biologists Wolfgang Klausewitz and Irenaeus Eibl-Eibesfeldt after the Austrian zoologist , marine scientists and divers Hans Hass and his research vessel Xarifa first Xarifania hassi named. Later it was scientifically renamed Heteroconger hassi .
characteristics
The earmark tube eel is a fish that can reach a maximum length of 40 centimeters. Its body is thin, with a circular cross-section averaging 14 millimeters in diameter. The head with the same diameter as the body appears shortened because the relatively large mouth is close to the large eyes. The nostrils are small and are located in the center of the upper lip. The body is white and covered with many small black spots. The earmark tube eel has three larger, distinctive black spots, one each on the gill opening, on the central part of the body and in the area of the anus. The growing specimens of this species have a very thin black body.
Distribution and way of life
The lobster tube eel is widespread in the tropical and subtropical waters of the Indo-Pacific , from the east coast of Africa including the Red Sea to Polynesia and south of Japan to New Caledonia . It lives exclusively in colonies of different sizes on sandy soils that are exposed to currents at depths of 15 to 45 meters. The earmarked tube eel digs a vertical burrow in the sand of the seabed. The walls of the building are stabilized by a secretion from its tail gland. He hides about two thirds of his body in this building. With the body visible outside the building, he directs his mouth towards the underwater current in order to catch drifting food. The earmarked tube eel feeds on zooplankton . As with other heteroconger species, individuals seldom leave their burrows. To mate, they move closer to the partner through the sand until contact is possible. Fertilized eggs and juveniles go through a planktonic phase before they reach a sufficient size to live in the substrate .
