Bat rays can grow a wing span of 1.8 metres and weigh up to 90kgs (although they typically range from 9.07 kg-13.61 kg.)

They live in a wide range of environments. They mostly eat mollusks, crustaceans, and small fish that lay on the seabed. These rays use their wing-like pectoral fins to move sand and expose both prey and prey animals. They do have a poisonous spine on their tails but only use it as defense when scared.

Bat rays can live up to 23 years. They mate annually, in the spring or summer, and have a gestation period of nine to twelve months. Their litters can contain 2-10 pups. When the pups emerge, their pectoral fins are wrapped around the body, the venomous spine is flexible, and covered in a sheath which sloughs off within hours of birth.
