Which Animal has its mouth like a hole?

Question

The animal has had legal protection in its country since 1895, and is the only living member of the more than 200 million year old order Rhynchocephalia. What is it?

Answer 1

Asian carp (not just one but two mouths like nig holes).

The Asian carp is a filter feeder, so it gets its food by pumping water over its gill rakers (the bony suspensions that project from the gill arches), and those rakers only exist in its real, top mouth. Actually, the hole will mostly just cause the carp to lose a lot of ingested food.
