Llittle Sleeper Shark

About the Llittle Sleeper Shark

The little sleeper shark is a species of sleeper shark found mostly in the Northeast Atlantic and the Western Mediterranean. It has also been recorded off the coast of Cuba. It lives at a depth range of 200 to at least 1,000 m, but it could be found at the bottom of even deeper waters.

Like other sleeper sharks, this is a slow-swimming species. They exhibit low activity. Their main prey is squid.

Little sleeper sharks are ovoviviparous. Litters of between 5 and 17 pups have been recorded. Young sleeper sharks become mature at about 70-80 cm and reach a maximum length of about 143 cm.

These sharks are often caught as by-catch but are almost never retained. By-catch mortality is very high. Unfortunately, there aren’t enough studies to track their population trends, and are currently considered  Data Deficient.
