What is frog crabs?

Frog crabs, also known as decorator crabs, are crustaceans that belong to the family Majidae. These crabs are named as "frog crabs" due to their resemblance to a frog when they curl their body and legs.

Frog crabs are found in various oceans around the world, mostly in tropical and subtropical waters. They have a soft outer shell; thus, they cover themselves with debris and small organisms such as algae, seaweed, sponge, and other attached animals. These crabs use their claws and legs to attach the items to their external skeleton, acting as camouflage to help them blend in with their surroundings.

Frog crabs usually grow up to 5 centimeters in length and are relatively inactive creatures. They feed mainly on small organisms such as plankton, algae, and other microorganisms.

Frog crabs are preyed upon by larger predators such as octopuses, seagulls, fish, and other crustaceans. Due to their unique ability to disguise themselves, they can remain hidden from predators to escape possible danger.

Overall, frog crabs are fascinating creatures that have developed an innovative survival mechanism in nature.
