Milk sharks, typically 1.1 m or 3.6 feet long, can be found in coastal tropical waters throughout the eastern Atlantic and Indo-Pacific regions. This species is common near the coast and in estuaries, and has been recorded swimming in rivers in Cambodia.

Milk sharks feed on small bony fish but also feed on squid and crustaceans. In turn, it often falls prey to larger sharks and possibly marine mammals. Similar to the rest of its family, the species is viviparous, with the developing embryo sustained by placental connections. Females give birth to one to eight cubs during the prescribed breeding season or year-round, depending on the location.
