Dauphins
Dauphins are small toothed whales that belong to the family Delphinidae. They are widely distributed in the world's oceans and are known for their playful behavior and intelligence. Dauphins are characterized by their sleek bodies, with a rounded head and a beak-like snout. They have a dorsal fin that is typically triangular and a tail fin that is used for propulsion. Dauphins are social animals and often travel in groups called pods. They are known to exhibit complex behaviors, such as hunting in groups and using tools, such as sponges, to protect their rostra from barnacles. Dauphins are also known for their echolocation abilities, which allow them to navigate and find food in the dark depths of the ocean. They are an important part of the marine ecosystem and are often used in scientific research to study marine life and ocean health. Dauphins are also popular subjects in marine conservation efforts, as they are threatened by human activities such as pollution, fishing, and climate change.
