Who are the crabs and lobster relatives?

The crabs and lobster's relatives are the other species that belong to the order called Decapoda. Decapoda is a diverse group of crustaceans that includes shrimps, prawns, and many other types of marine creatures. Some of the main groups of decapods that are related to crabs and lobsters include:

1. Shrimps and Prawns: Shrimps and prawns are one of the most common types of decapods. They are characterized by their long, slender bodies, and five pairs of walking legs. Shrimps are typically smaller than prawns, and they have long antennae.

2. Crayfish: Crayfish are freshwater crustaceans that are closely related to lobsters. They have a lobster-like body, but they are typically smaller and have shorter antennae. Crayfish are found in a variety of freshwater habitats, including rivers, streams, and lakes.

3. Hermit Crabs: Hermit crabs are a unique group of decapods that live in empty shells of other animals, such as snails or clams. They have soft bodies and a pair of large claws, which they use to grasp the shells. Hermit crabs are found in a variety of habitats, including rocky shores, coral reefs, and tide pools.

4. True Crabs: True crabs are a large and diverse group of decapods that includes a variety of species, including blue crabs, fiddler crabs, and Dungeness crabs. True crabs are characterized by their five pairs of legs, with the first pair of legs modified into claws.

5. Lobsters: Lobsters are large, marine crustaceans that are closely related to crabs. They have a muscular tail and a pair of large claws, which they use to capture prey. Lobsters are found in a variety of marine habitats, including rocky shores, coral reefs, and the open ocean.

These are just a few examples of the many decapods that are related to crabs and lobsters. Decapods are a fascinating group of organisms, and they play an important role in the marine ecosystem.
