Blue whale The blue whale, the largest animal on Earth, is a filter feeder that consumes small shrimp-like animals called krill. They have baleen plates instead of teeth, which act as a filter to strain out water and trap their prey.

Anteater Anteaters have long, sticky tongues to capture and eat ants and termites. They lack teeth and swallow their prey whole.

Pangolin Pangolins, also known as scaly anteaters, have no teeth. They have long, sticky tongues like anteaters and feed mainly on ants and termites.

Sloth Sloths have reduced and specialized teeth. They possess small peg-like teeth with no enamel, which are mainly used for grinding leaves.

Beluga whale Beluga whales have a flexible mouth and a row of peg-like teeth. While they do have teeth, they are not used for chewing  or tearing prey. Their teeth are mainly used for catching  and holding fish.

Whale shark  Whale sharks are the largest fish in the world. Despite  their enormous size, they have no teeth. Instead, they have sieve-like filter pads in their mouths that they use to filter out small organisms like plankton from the water.

Leatherback sea turtle  Leatherback sea turtles have a specialized diet of jellyfish. They lack teeth and instead have sharp, pointed cusps in their mouths that help them grip and swallow their gelatinous prey.

Sea otter Sea otters primarily feed on shellfish, such as clams and mussels. They lack teeth for crushing shells and instead  use rocks and other tools  to break them open.

Barnacle Barnacles are intriguing  marine crustaceans that attach themselves to surfaces, showcasing remarkable adaptations for filter-feeding  and survival in their  aquatic environment.
