The Family Squatinidae, commonly known as the angel sharks, are a group of elasmobranch fish that can be found in shallow and deep waters around the world. These sharks are known for their distinct shape, which resembles that of a ray with a well-defined head and body. Synonyms for Family Squatinidae include the common names Squatina and monkfish, as well as the scientific names Rhina and Squatinae. These sharks are important predators in their ecosystems, and have been historically targeted for their meat and liver oil. However, many populations of angel sharks are now considered endangered due to overfishing and habitat destruction.
