Dolphins

Dolphins are one of the most beautiful and friendly sea creatures. They are also very intelligent and are found to use tools for hunting. Most of the dolphins after they become 2-year-old use sea-sponges for hunting the fishes. These sponges help them in catching fishes that lack swim bladders. Also, sponges protect the rostrum (beak or snout) of the dolphin when their vision is less effective while hunting.

Mostly dolphins that dwell in the areas where sponges occur frequently so that they can use more sponges as a tool. Other than sponges, some bottlenose dolphins are found to use conch shells as a tool by inserting their rostrums in them.
