Epaulette sharks adapt well to aquarium life and readily breed in captivity. They show little fear of humans, but are often injured by being handled by beachgoers while out of the water.
The dusky shark is among the slowest and latest-maturing of known sharks, with males becoming sexually mature at 2.79 m (9.15 ft), at around 19 years old, and females at 2.84 m (9.32 ft), at around 21 years old.
Smalleye hammerheads are among the smallest of the hammerhead species and as such often fall prey to larger sharks such as bull sharks or other hammerheads.
