Diet and Hunting

• Otters are carnivorous and primarily feed on fish, crustaceans, and mollusks.
• They use their sharp claws and teeth to catch and eat prey.

• They were heavily hunted for their valuable fur, leading to population declines.
• Several species, such as the sea otter and giant otter, are endangered.
• Conservation efforts include protected areas, anti-poaching laws, and habitat restoration.
• Organizations work to rescue and rehabilitate injured and orphaned otters.

Human Interaction

• Otters are popular in zoos and wildlife sanctuaries.
• Eco-tourism and wildlife documentaries help raise awareness about otter conservation.
• Efforts are being made to reduce plastic pollution that harms marine life.
• Scientific research on otters contributes to understanding marine and freshwater ecosystems.
