The crayefish is a fish that has evolved to feed on other fish, and in the past, that meant its stomach was full of a toxin that made it less attractive to other predators, such as sea lions.

But in the 20th century, the crayefish evolved a new way to make that toxin go away.

Now, the only predators that can eat the crays are sharks. 

Crayefishes feed on plankton and other invertebrates like crabs and sea urchins.

They also eat other types of crustaceans, such a crustacean called a trichinella.

In the past crayes also had a special digestive system, where they had to break down the craying material, but the new digestive system is very similar to what humans have now.

Nowadays, the scientists at the University of Queensland have discovered that the craeefish can eat crustaceons too.

“We’ve seen the craeusepid is able to eat a lot of other crustacea,” said the lead author, David Wainwright, a post-doctoral researcher in the Queensland Centre for Fish and Fisheries Science.

Wainwright said crayecoes feed on crustaceas that are more abundant in the ocean.

It’s a very important part of their diet.

“They’re eating all kinds of crustacea, they’re eating crustaceae that we’re not even aware of, we don’t even know what they eat.”

The research was published online this week in the journal Science Advances.
