Blue whales are filter feeders, meaning they strain tiny organisms called krill from the water. Dolphins are much too large to be swallowed by a blue whale.
Here's why:
* Diet: Blue whales primarily feed on krill, small crustaceans, and sometimes small fish.
* Size: Dolphins are much smaller than blue whales and are not part of their diet.
* Feeding mechanism: Blue whales use baleen plates in their mouths to filter food from the water. Their throats are not designed to swallow large prey like dolphins.
While blue whales and dolphins may sometimes share the same habitat, they have different food sources and ecological roles.
