Carcharhinus Borneensis

This shark belongs to the requiem shark family, a diverse group that includes many familiar coastal and reef species. Use the entry as a cautious base note: sleek shape, active swimming, and live-bearing reproduction are common family themes. Typical requiem sharks are streamlined, with two dorsal fins, an anal fin, five gill slits, and a distinct nictitating lower eyelid. Color is often gray to bronze above with a pale underside. Requiem sharks occupy tropical and warm-temperate seas worldwide, from coastal estuaries and reefs to outer shelves and open ocean. Individual species may be strongly coastal, strongly pelagic, or somewhere in between.

Overview

This shark belongs to the requiem shark family, a diverse group that includes many familiar coastal and reef species. Use the entry as a cautious base note: sleek shape, active swimming, and live-bearing reproduction are common family themes. Typical requiem sharks are streamlined, with two dorsal fins, an anal fin, five gill slits, and a distinct nictitating lower eyelid. Color is often gray to bronze above with a pale underside. Requiem sharks occupy tropical and warm-temperate seas worldwide, from coastal estuaries and reefs to outer shelves and open ocean. Individual species may be strongly coastal, strongly pelagic, or somewhere in between.

This family uses an unusually wide span of habitats, including surf zones, mangroves, coral reefs, seagrass flats, shelf edges, and oceanic waters.

Why it matters: Many requiem sharks depend on shallow nursery grounds where pups spend their early months away from larger predators.
