How the seahorse gained its shape

Seahorse curves help them grab distant prey

The shape of seahorses allows them to grab prey at a distance, according to Sam van Wassenbergh, a biologist from Antwerp University, Belgium. He and his team created mathematical models comparing seahorses with pipefish, which lack the seahorses' curved shape. The seahorses' curves give their necks stability and elasticity, giving them greater range. This helps to offset their poor swimming abilities.
