Dolphins use sponge gloves to hunt: The clever trick is passed from mothers to their calves. Scientists share fascinating story of dolphins' hunting technique

In Shark Bay, Australia, some bottlenose dolphins use marine sponges as hunting tools, placing them over their beaks while searching for prey buried in sand. A study found that only about 11% of adult females use the technique, with most learning it from their mothers. Young dolphins typically begin carrying sponges at two to three years old, while researchers also documented another tool-using group that catches fish using seashells.
