Description

Habitat

Typically found in water with a depth of 0 to -3,146 meters (0 to -10,322 feet).[1]

Ecology: The biology and distribution of A. kampae is poorly known due to confusion with other Apristurus species, and its deepwater habitat . It occurs near the bottom over the upper continental slope down to 1,888 m depth. Maximum reported size is 58.4 cm TL (Nakaya and Sato 1999). Reproduction is oviparous , with a single egg laid per oviduct .

Apristurus egg cases are usually thick-walled and about 5 to 6.8 cm long and 2.5 to 2.9 cm wide. The anterior end of the case has a long weak fibrous thread on each corner. The posterior end usually has two small processes, each with a long coiled tendril . As in shallow water scyliorhinids the coiled tendrils are probably used to attach the egg cases to hard substrates and/or biogenic structures as they are laid. Where reported the diet of Apristurus species usually includes crustaceans (penaeid shrimps, euphausiids ), squids and small fishes . [2].

The genus Apristurus contains at least 32 described species and a relatively large number of potentially undescribed ones. Morphological conservatism and, until recently, a lack of objectively defined characters makes this one of the most taxonomically confused shark genera (Compagno 1984, Nakaya and Sato 1999).

Nakaya and Sato (1999) defined three species groups within Apristurus: the longicephalus-group (two species), brunneus-group (20 species) and spongiceps-group (10 species). A. kampae belongs to the spongiceps-group, characterized by: a short, wide snout (prenarial length
