Angelsharks (Squatina squatina) bury themselves in sand or mud lying in wait for prey, which includes fish, crustaceans and various types of mollusks.
Lemon sharks are viviparous, females giving birth to between 4 and 17 young every other year in warm and shallow lagoons. The young have to fend for themselves and remain in shallow water near mangroves until they grow larger. With increasing size, the sharks venture further away from their birth place. At maturity at a size of 1.5 to 2 m and an age of 12 to 15 years, they leave shallow water and move into deeper waters offshore. However, little is known of this life stage. Maximum recorded length and weight is 340 cm and 183 kg. Bahamas.
