They are typically small to medium in size, although a few species can reach lengths of greater than 39 inch. They are most diverse in the tropics, relatively uncommon in the temperate zone and completely absent from cold waters.

These species are found in disjunct tropical regions of South America, Central Africa and Southeast Asia.
