Family No. 127: TRACHICHTHYIDAE
by P.C. Heemstra
Slimeheads
Slymkoppe
Body oval, compressed. Head with large, skin-covered
mucous cavities, the walls between these cavities often with
serrated crests; preopercle with a prominent spine at the
angle; one supramaxilla; jaws with bands of minute teeth.
Dorsal fin with 3-8 striated spines and 10-19 soft-rays, its
base about twice length of anal-fin base. Anal fin with 2 or 3
spines and 8-12 soft-rays. Lateral-line scales more or less
enlarged; scales along midventral part of belly enlarged,
forming a row of well-developed scutes in most species.
Medium-sized fishes (to about 60 cm total length) occurring near the bottom in depths of 100 to 1 000 m. Several
species of slimeheads are worldwide in distribution and
some are reported to be common in certain areas. Five
genera with about 30 species. Trachichthodes spinosus Gilchrist was assigned to this family by Smith (SFSA No. 293),
but this species is here placed in the Berycidae.
