What is a frilled sharks predator?

Are Dragon sharks real?

Biology. Dragon Sharks are a large and dangerous type of shark. They have very rough skin similar to a Sharpedo, but are nearly unmatchable in speed underwater.

Are frilled sharks dangerous to humans?

Frilled sharks are possibly the most primitive sharks in the oceans, dating back to 150 million years virtually unchanged. They are not considered dangerous to humans, mostly because we seldom meet one, and in fact the only people who tend to see them at all are fishermen and scientists.

What eats a frilled shark?

The frilled shark eats a diet of cephalopods, smaller sharks, and bony fish; 60 percent of the diet is composed of squid varieties, such as the Chiroteuthis, the Histioteuthis, and the Onychoteuthis, the Sthenoteuthis and the Todarodes; and other sharks, as indicated by the stomach contents of a 1.6 m (5.2 ft)-long frilled shark which had swallowed a 590 g (1.30 lb) Japanese catshark (Apristurus japonicus).
