Frilled sharks have existed for around 80 million years, making them one of the oldest species of sharks still around today. Their unique physical characteristics and deep-sea habitat have allowed them to remain relatively unchanged over the millennia.
The long jaws of the frilled shark are highly extendable with an extremely wide gape, allowing it to swallow whole prey over half its size. However, the frilled shark can not deliver a strong bite. Frilled sharks eat cephalopods (such as molluscs), osteichthyes (also known as bony fishes), and smaller sharks. The many needle-like teeth of the frilled shark are suited for ripping soft-bodied squid.

-sharks have cartalige, NOT bones -the myth "a shark can sense a drop of blood in an olympic sized swimming pool", not true. they could smell a drop of fish blood, not human blood...-the dorsal fin on a shark is bent backwards-sharks can have anywhere between 5-7 gills-sharks are attracted to flashy/bright/highly contrasting colors because they remind them of a fish-sharks can range from being able to hold them in your hand, to being over 60 feet long
The answer to that is no. When sharks where first sited there was only coral, brain coral was not devopled then.
Sharks have been around even before dinosaurs have. Scientists really dont know when but, they do know is that they are the longest living creatures in time.
Yes there are many types of sharks in Long Island Sound. Sand Tiger Sharks are the most common which are in the aquarium at mystic. There have been sightings of Great White Sharks in the sound also. Brown, Hammerhead, and Thresher sharks have all been caught in Long Island Sound.
Sharks have been around for hundreds of millions of years. This means that their teeth have been available to the fossilization process for a long time.
depends on the lizard.
Frilled sharks have never been kept in captivity. In the wild it is hard to know just how long these fish live. Because they are deep benthic creatures there is little information on lifespan. However, one source (Parker and Parker, 1999) estimates maximum lifespan at 25 years.
