Unusual and beautiful sea horses for centuries caught the imagination of people. But now scientists have figured out why this unusual fish has a horse’s head and s-shaped body.

The study, published in the journal Nature Communications, found that compared with unbent sea needle, which is their evolutionary ancestor, seahorses can get a more distant prey.

The team concluded that the unusual shape gives them an advantage in hunting and getting food. And seahorses and pipefish feed on small marine creatures, attacking and sucking them.

But in contrast to the bulk of the pipefish, which swim to their prey, seahorses, wait until their prey is not swims past them herself.

With the rapid filming and mathematical models, Sam Van Wassenberg of the University of Antwerp in Belgium, showed that the curvature in the neck helps seahorses get to more remote mining.

"They’re turning my head up to their mouth was closer to production," a passing over them ’"- said Wassenberg.

"My theory is that they evolved from pipefish, changing the way of hunting," - said Wassenberg.

The behavioral shift towards a "wait and see" hunting, indicates that it was necessary to catch prey while away from them.

These fish eventually turned into s-shaped seahorses that use your body for a surprise attack.

"They attach the tail to the algae and wait until the prey is within striking distance swims," - he said.
