How dolphins may become stranded in waters with gently sloping shorelines

The video explains how dolphins use echolocation to detect objects in water. When sound waves hit an object, they bounce back as echoes, which dolphins interpret. However, in areas with gently sloping shorelines, echolocation signals can reflect multiple times off the sea surface and bottom, leading to energy and detail loss, making dolphins vulnerable to stranding.

What is the purpose of echolocation in dolphins?

What happens to the echolocation signal when it hits an object?

How does a dolphin interpret the echoes it receives?
