Overview

One of the largest bottom-dwelling sharks globally. Its six gill slits reflect a primitive anatomy unchanged for millions of years. Typically inhabits deep water, rising toward the surface at night to feed.

Habitat

Marine or benthic and pelagic. The shark is found on continental and insular shelves and upper slopes, from the surface to 6,150 ft [1875 m]. Juveniles are often found close inshore.

Distribution

Temperate and tropical seas.

Behavior

The shark is sluggish, but it is a strong swimmer. Apparently it is nocturnal and very sensitive to high light levels.
