They are relatively small sharks, with the largest species reaching no more than 121 cm (48 in) in adult body length. They have elongated, cylindrical bodies, with short barbels and large spiracles. As their common name suggests, they have unusually long tails, which exceed the length of the rest of the body. They are sluggish fish, feeding off bottom dwelling invertebrates and smaller fish.
