Nature published a paper entitled “An adaptive explanation for the horse-like shape of seahorses” last January, which postulates that the horse-like shape of the seahorse gives it a distinct advantage when feeding over its evolutionary relative and ancestor, the pipefish. The study used biomechanical analysis to “show that the seahorse’s peculiar head, neck and trunk posture allows for the capture of small shrimps at larger distances from the eyes compared with pipefish”. This in turn enlarges the volume of water they can probe for food.
