Most mackerel sharks have long snouts and mouths that stretch behind the eyes.
They also feature two dorsal fins and an anal fin. These species range from intertidal areas to open ocean at depths of nearly 4,000 ft. Embryos of these sharks dine on their younger siblings and fertilized eggs in the womb. The gill openings are short and there are precaudal pits but no lateral caudal keels. They reach depths of 630 to nearly 4,000 ft.
