One of the 26 sharks on WAnimals

Silky Shark (Carcharhinus falciformis)

Cartilaginous fish · Carcharhiniformes · Carcharhinidae

Silky Shark

Carcharhinus falciformis

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The silky shark owes its name to its skin, noticeably smoother and softer than that of other sharks. It is one of the most abundant oceanic sharks and also one of the most heavily caught: millions of individuals are estimated to die each year as bycatch in the tuna fishery, above all around fish aggregating devices.

Fun facts

  • It is one of the principal victims of the tuna fishery: it gathers beneath the fish aggregating devices used by purse seiners, and millions of individuals die each year as bycatch across the tropical oceans.
  • Its skin is noticeably smoother than that of other sharks because its dermal denticles are smaller and more closely set, hence its name.
  • It is extraordinarily inquisitive and approaches divers and boats, behaviour that makes it especially vulnerable to targeted fishing.

How to help

The silky shark is classified as vulnerable. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 17 protected areas — one reason why protecting these places matters for its conservation.
