More Info
Family Taxonomy |
A monotypic family (contains a single species). |
Family Distribution |
Found worldwide in all major oceans, inhabiting meso- and bathypelagic waters. |
Family Description |
Females - body slender, elongate, somewhat compressed, head short, eyes minute, poorly developed, olfactory organs degenerate, nostrils absent; mouth large, extending well beyond eye; teeth in jaws short, immobile, widely spaced; outer margins of jaws with conical protruberances bearing 2-3 series of long hinged teeth with hooked tips. No bioluminescent luring apparatus, modified first dorsal spine absent, soft dorsal and anal fins moderate, not far posterior on body; pelvic fins absent. Skin naked. Males - smaller than and parasitic on females; eyes and olfactory organs poorly developed. Premaxilla with 2 teeth, lower denticular with three hooked projections, upper denticular teeth absent. Skin naked. |
Family Size |
Females to 108.5 mm SL, males to 18 mm SL. |
Family Feeding |
Unknown, but possibly feed on by snagging prey items with the long, hooked teeth outside their jaws. |
Family Reproduction |
Reproduction is oviparous, and eggs and larvae are pelagic. Larvae are elongate, slender, with the skin only slightly inflated; rudimentary illicium protrudes from snout tip; pectoral fins small, pelvic fins absent. Larvae begin metamorphosis at 8-10 mm SL. |
Family Commercial |
Of no commercial importance. |
Family Conservation |
None. |
