39 Fish that Are Endangered (List with Pictures)

39 Fish that Are Endangered

Examples of fish that are endangered include angel shark, Atlantic bluefin tuna, Atlantic goliath grouper, Atlantic halibut, and beluga sturgeon.

Just like other animals, fish populations can decline for a variety of reasons, including habitat loss, overfishing, and pollution. As a result, many species of fish are now facing extinction. Endangered fish include well-known species such as bluefin tuna and sturgeon.

This blog post highlights some of the most endangered fish species and their habitats.

Examples of Fish that Are Endangered
