Systematics of the Pearlfishes (Pisces: Carapidae)
Abstract and Figures
A cladistic classification based on swimbladder morphology, developmental and osteological characters of the vertebral column, fins, pectoral and pelvic girdles, gill arches, ethmoid, jaws, and habitat is presented. A total of 31 species in 7 genera are recognized in 2 subfamilies. The family is distributed over broad depth (0-2000 m) and latitudinal (65°N to 60°S) ranges. In general taxa with more plesiomorphic characters are found in deeper water and higher latitudes while taxa with more apomorphic characters are found in tropical, shallow water. Highly specialized inquiline behavior is found in both tribes and the phylogenetic hyopthesis specifies independent acquisition of molluscan inquilinism, at least. Within the Carapini the genus with the most apomorphic characters, Encheliophis, is the most successful holothurian inquiline and the only holothurian inquiline in the Indo-Pacific. Species in its sister genus, Carapus, "switch' to non-holothurian primary hosts (asteroids or ascidians) when sympatric with Encheliophis in the Indo-Pacific. Atlantic species of Carapus retain holothurians as primary hosts. Vicariance of sister species is frequently along depth or latitudinal gradients. -from Authors
