When the Indus River Dolphin surfaces to breathe it makes a sound similar to a sneeze.
Indus River dolphins generally dive for 30-90 seconds, but are capable of holding their breath for up to several minutes. During dives they use their long beaks to probe the sediment along the bottom of the river to feed on prey such as clams, fish, and shrimp. They have 26-39 pairs of teeth in each jaw that are useful for grasping prey. The fang-like teeth in the lower jaw are comparatively longer and curved, and may interlock, overlap, and be visible outside the mouth. As these animals get older, the teeth become worn-down. Groups may coordinate their movements to cooperatively feed on prey.
