Boarfishes
Beervisse
Body strongly compressed, discoid, with small ctenoid
scales. Mouth small; upper jaw protrusile; bands of small
teeth on jaws, none on vomer or palatines. Single dorsal fin
with 8 or 9 spines and 25-30 soft-rays; anal fin with 3 spines
and 25-27 soft-rays; dorsal and anal fin rays branched.
Pelvic fins with 1 strong spine and 5 soft-rays. Caudal fin
truncate, with 10 branched rays. Pectoral fins longer than
pelvics, slightly shorter than head, with 13 rays. Cheeks and
operculum with distinct scales. Gill membranes free from
isthmus; branchiostegal rays 6. Vertebrae 9+ 12.
Moderate-sized fishes (to about 22 cm total length) in
tropical and temperate waters of all oceans. Boarfishes live
near the bottom in depths of 50 - 600 m; the larvae are
pelagic. Two genera; Capros Lacepecte, 1802 is monotypic;
C. aper (Linnaeus, 1758) is common in the North Atlantic
and Mediterranean. Antigonia Lowe, 1843 comprises about
5 valid species (Berry, 1959); 1 species occurs in our area.
