Uristidae

摘要

Two genera and three species of uristid amphipods are reported from the Great Barrier Reef, Queensland, Australia. All are considered to be scavengers which can be common in areas where they occur. Members of the Uristidae occur in all world oceans from shallow water to the deep sea. With bodies adapted to swimming, callynophores in males and females for detecting the most minuscule scents and mouthparts adapted for cutting and slicing, uristids are highly specialized for scavenging on carrion and for predation. Although best known in cold temperate and polar seas they also occur in tropical environments. In this paper we report two genera and three species of uristid amphipods from the Great Barrier Reef. Two of these species, Ichnopus capricornusLowry & Stoddart, 1992 and /. tenuicornis (Haswell, 1879a), appear to be endemic to tropical Australia (Lowry & Stoddart 1992, 2003). The third species, Nagada uwedoae Lowry & Stoddart, 1995, is known also from northern Papua New Guinea.
