Here's why:
* Streamlined bodies: Dolphins have streamlined bodies designed for speed and agility in the water. This makes it difficult for them to manipulate food with their jaws.
* Teeth for grasping: Their teeth are primarily used for grasping prey, not for chewing.
* Powerful digestive system: Dolphins have strong digestive systems capable of breaking down fish bones and scales.
While they may occasionally tear off small pieces of larger fish, swallowing whole is their primary feeding method.
