Biology and Ecology
Accounts of bigeye sand tigers captured alive note extremely aggressive behavior, thrashing and snapping violently in and out of the water. Its large eyes suggest deepwater or nocturnal habits. The nighttime capture of bigeye sand tigers on pelagic longlines set at relatively shallow depths brings up the possibility that it migrates vertically into the epipelagic zone at night to feed. The stomach of a specimen from the Gulf of Mexico contained squid beaks and otoliths from unidentified bony fishes. Nothing is known of its reproduction, though it is presumed to be aplacental viviparous with oophagous embryos as with the other members of its family. Males and females are sexually immature at 2.2 m (7.2 ft) and 3.2 m (10.5 ft) respectively, indicating that maturation occurs at a larger size than in the sand tiger shark.
