20 Amazing Facts About Frilled Sharks

Join us on an exhilarating journey through the enigmatic waters, where the rulers are none other than sharks.


1. These remarkable creatures are often referred to as «living fossils» and are considered relics of the world’s oceans by scientists. Meet the Chlamydoselachus anguineus, or as we like to call it, the «Cloak-Wearing Snake Shark.»

2. Now, here’s the exciting scoop – a recent discovery has revealed a second species of Frilled shark, or cloaked shark, residing in the waters of Africa. It turns out this unique shark has more surprises up its sleeve, challenging the previous belief that there was only one species.

3. Imagine encountering a creature that’s small in size, measuring just 1.3 to 1.5 meters. Its body resembles a snake, with gills covered in strips of skin that look like a folded cloak. Quite an intimidating appearance, right?

4. Adding to its mystique, the Frilled shark has its mouth located at the end of its snout, a departure from the typical placement in most other sharks. This feature gives it a distinctive, snake-like look.

5. But the real showstopper? The shark’s jaws boast about 300 sharp teeth, arranged in an impressive 28 rows. What makes these teeth truly fascinating is their three equally long peaks, resembling tiny tridents. Now that’s a dental arrangement you don’t see every day!

6. In terms of fashion, the Frilled shark keeps it simple with a dark brown colour – no spots or decorations. Surprisingly modest, but this colouration serves a purpose, making the shark less noticeable in its habitat.

7. Prepare to be amazed: the most incredible aspect is that the Frilled shark’s distant ancestors lived a staggering 150 million years ago! Yes, you read that right.
