If you were swimming in the ocean and saw a Japanese giant spider crab, you'd probably run from the water screaming. You might think you're in a horror movie! Imagine a crab with legs that can stretch about 12 feet across! The Japanese call this creature taka-ashi-gani, which means 'tall legs crab.' It's the largest crab in the world and may live up to 100 years. Luckily, you won't ever have to worry about running into this giant animal. It lives in a very small area of the ocean, near Japan. Spider Crabs Japanese giant spider crabs live in very deep water. They usually can be found in water that is between 400-900 feet deep but have been known to go as deep as 2,000 feet! The crabs can be found living in vents and holes on the ocean floor. These large creatures move into shallower waters to reproduce, and young crabs can be found there, as well. Since Japanese giant spider crabs have weak legs and move slowly, they need to hide from their predators, as they could never get away from them quickly enough. To help them hide, the color of their bodies blends in with the floor of the ocean. These crabs actually decorate their bodies so that they're even harder to find! They use sponges and seaweed to make themselves look even more like the ocean floor. This is an example of their habitat helping them stay safe!

Japanese Spider Crab Profile The Japanese spider crab is a giant crustacean that can grow up to 12.5 feet that is most commonly found on the Pacific side of Japan. At first glance, they look like ancient monsters that have crawled straight out of a sci-fi movie. However, in the marine community, they are known to be gentle giants. Understandably, their names are inspired by their resemblance to a well-known arachnid – spiders. Japanese Spider Crab Facts Overview Habitat: Seabed at depths between 160 to 2000 feet (50-600 m) deep, thrive at water temperatures of approximately 50 degrees Location: Pacific side of Japan and Taiwan Lifespan: Up to 100 years Size: Up to a 12.5 foot leg span Weight: Around 42 pounds Color: Orange and white bodies with long spiny legs Diet: Omnivore: plants, algae, mollusks, shrimp, small fish Predators: Large fish, stingrays, octopuses Top Speed: Unknown No. of Species: 1 Conservation Status: Not evaluated (IUCN) As a species of marine crab, these crabs are often found inhabiting holes and pits on the ocean floor between 160 – 2,000 feet in depth. Living at such deep depths and covered in a thorny protective exoskeleton, with 10 giant legs – these animals have few natural predators. They are omnivorous, and they diet on dead and decaying animals and plant matter on the sea bed. They may at times also eat live fish that come there way. Japanese spider crabs have not been evaluated by the IUCN and are not currently categorized as an endangered spec...

Reading Time: 5 Minutes • A SINGLE GIANT SPIDER CRAB can be hard to see. It barely exceeds 15cm across, despite its common name, and its triangular upper shell is covered in spines, hairs and knobs that make it blend into an ocean floor background. It will even make itself more inconspicuous by placing living sponges, hydroids and algae onto its shell from the surrounding temperate reef environment where it lives. But when this species comes together en masse, in aggregations that can exceed 50,000 individuals, it’s difficult to miss. Seeking shelter in the upper reaches of a jetty, the crabs find safety in numbers as they moult almost simultaneously and their yet-to-harden shells make them vulnerable to predation. (Image credit: Justin Gilligan) Spider crabs converge like this at several locations in Australia – including in South Australia and Tasmania – but no aggregation is as predictable or easily accessible as that in Port Phillip. The timing of this great assembly usually occurs between late May and June, and relates to lunar cycles when the water temperature is a fresh 11–15°C. Sprawling across 1930sq.km with a depth of up to 24m, Port Phillip contains some of Victoria’s most important types of marine environment. Vast areas of undulating sand, thriving seagrass meadows and distinct areas of rocky reef create complex habitats that are home to a huge diversity of marine wildlife, including weedy seadragons, brightly coloured nudibranchs, pot-bellied seahorses and gi...

spider crab, any Majids, a widely distributed marine group, are fished commercially in temperate waters, such as in the North Pacific. Some are quite small; for example, the long-beaked spider crab ( Macropodia rostrata) of European coastal waters has a body about 1 cm (less than 0.5 inch) in diameter. The largest spider q.v.) of the Pacific waters near Japan. The outstretched claws of this crab ( Macrocheira kaempferi) measure more than 4 m (13 feet) from tip to tip. Animal Factoids The head of the spider crab is rather beak-shaped; the body surface is generally covered with hairs, spines, and tubercles (knobby projections) that are frequently matted with algae, sponges, and other organisms. The crabs fasten a good deal of this material to themselves by means of a mucuslike secretion from the mouth. The Pugettia producta), a spider crab found among seaweed on the Pacific coast from Canada to Mexico, is about 1.25 cm (0.5 inch) wide and 2.5 cm (1 inch) long. It is green and red on top and green underneath. Parthenope investigatoris, a spider crab of the Spider crabs of the genera Hyas, Sternorhynchus, Pitho, and Lambrus are common on the Atlantic coast of Loxorhynchus, Pugettia, and Epialtus.

It has an orange body with white spots on its legs. The short, stubby eye stalks are located on the front of the carapace and two thin spines stick out between them. Short, spiny tubercles also cover the carapace. In male specimens, the limbs on which the claws are located become longer than its other limbs. Size: The Japanese spider crab is one of the largest living arthropods. Fully grown it can reach a leg span of 12 feet (3.7 m), a body size (carapace width) of 15 inches (38 cm) and weigh as much as 44 pounds (20 kg). The width of the oval-shaped and vertically rounded shell can reach up to 12 inches (30 cm) and can be up to 16 inches (41 cm) long. Males are larger than the females. Behavior: In spite of its ferocious appearance, it has a gentle, calm disposition. Unable to swim, they spend much of their time crawling on the sea bed, foraging for food. Diet: Japanese spider crabs are omnivorous and scavenge for food. In its natural habitat it feeds on shellfish and dead animals. They can eat algae, plants, mollusks and small fi...

When researchers attempted to reconcile the evolutionary history of crabs in all their raucous glory just earlier this year, they arrived at the conclusion that the defining features of crabbiness have evolved at least five times in the past 250 million years. What's more, crabbiness has been lost possibly seven times or more. This repeated evolution of a crab-like body plan has happened so often it has its own name: carcinization. (And yes, if you lose crabbiness to evolution, it's called decarcinization.) Emerita portoricensis) and various lop-sided hermit crabs – but then A Puerto Rican sand crab. (Michelle Barros Sarmento Gama/iNaturalist/CC BY-NC 4.0) Why evolution keeps crafting and shafting the crab-like body plan remain but a mystery, though evolution must be doing something right in fashioning crabby creatures time and time again. There are thousands of crab species, which thrive in almost every habitat on Earth, from coral reefs and abyssal plains to creeks, caves and forests. Crabs also boast an impressive display of sizes. The smallest, the pea crab ( Pinnothera faba), measures just millimeters, while the largest, the Macrocheira kaempferi), spans nearly 4 meters (around 12 feet) from claw to claw. With their species richness, extravagant array of body shapes and rich fossil record, crabs are an ideal group to study trends in biodiversity through time. But finding some order in the chaos of crabs is an ongoing challenge. What's a crab, anyway? It gets weirder, ...
