Contender 1: Crab

Crabs are decapod crustaceans known for their characteristic thick exoskeleton and a pair of robust claws. They vary in size from the tiny pea crab, a few millimeters wide, to the giant Japanese spider crab, with a leg span of up to 4 meters. Crabs are typically found in the ocean, but some species are also found in freshwater or on land. Notably, crabs are known for their sideways walking, a motion that distinguishes them from other crustaceans.

Fun Fact: Crabs communicate with each other by drumming or waving their pincers, which is not just a sign of aggression, but can also be a part of their mating rituals.

The Japanese Spider Crab, scientifically known as Macrocheira kaempferi, is an enormous arthropod inhabiting the Pacific waters of Japan. Known to reach staggering leg spans of up to 12 feet and weighing up to 42 pounds, this species of crab boasts an intimidating appearance. Its body is covered in a spiny exoskeleton that varies in color from a reddish-orange to a pale white, providing excellent camouflage against the ocean floor. Notable physical features include long, slender legs with sharp claws used for defense and prey capture, as well as a rounded carapace that protects its soft abdomen and organs.

Fun Fact: The Japanese Spider Crab is not only famous for its impressive size but also for its remarkable lifespan, often living for over 100 years, making it one of the longest-lived arthropods on our planet.

Fun Fact: Despite their intimidating appearance, Japanese Spider Crabs are known for their gentle nature and prefer a diet consisting mainly of dead animals and small fish.
