How long do yeti crabs live for?

Yeti Crab Facts Overview

Yeti Crabs live in the deep oceans, in hydrothermal vents, which are deep within the ocean. These vents provide hot water which makes up the environment where these crabs live. The crabs regulate their ecosystem by using their hairy arms to collect toxins released from the hydrothermal vents.

The crabs reproduce by Releasing many larvae into the water so that a handful reach other vents and colonise them. But it is thought that they survive for only a short time in open waters; so a strong west-to-east current around Antarctica may have aided their spread. The animal was discovered in 2011.

The yeti crab is a blind deep-sea crab With reduced eyes and long bristles on its body. It lives near hydrothermal vents.

Unlike its Abominable Snowman namesake, this clawed crustacean ranges in length from Half a foot (15 centimeters) to under an inch (0.5 centimeter). It’s only the third known species of yeti crab, a group of shaggy-armed creatures first discovered in the South Pacific in 2005.

The researchers saw more of these unusual crabs during subsequent Alvin dives. Most of the crabs were living at depths of about 2,200 meters (7,200 feet) On recent lava flows and areas where warm water was seeping out of the sea floor.

They have Ten legs arranged in five pairs, although some of the legs may not be visible when an animal is viewed. They also have a pair of long antennae on their head and a pair of compound eyes on stalks. The development of the eyes and the ability to see seem to be reduced in yeti crabs.

Genetic evidence suggests this species branched off from its family’s common ancestors before the others, meaning that Yeti crabs may have first evolved in these relatively less-extreme environments and later migrated to hot hydrothermal vents, Roterman said.

As for weight and diet, the Yeti Crab can grow to be 5 or 6 inches long, and can weigh anywhere from 2 to ~5 pounds.

Yeti Crab Facts Overview

However, unlike fish, Blue crabs can survive out of water for long periods of time-even over 24 hours-as long as their gills are kept moist. When out of water, crabs will seek out dark, cool, moist places to help prevent their gills from drying out and to hide from predators.

The habitable zone in which yeti crabs can survive is dangerously small—too close to the vents and they will instantly fry, too far and they can die of hypothermia. To stay alive, The crabs must pile on top of one another, clinging onto each other and the seafloor.

Their unique physiological adaptations let the crab harvest large clusters of bacteria that grow on the surfaces of hydrothermal vent chimneys. The bacteria, by the way, live in total darkness and so use a chemosynthetic process – not a photosynthetic process, or process involving sunlight – to produce food.

It is Very difficult to breathe, let alone find food. Remarkably, Yeti crabs grow their own food by farming sulfur-“consuming” vent bacteria on dense mats of body “hair” on their bellies. Moreover, they have a very important adaptation – greatly enlarged gill chambers that improve respiration.

Deep-sea species farms bacteria on its own claws. In the deep ocean off the coast of Costa Rica, scientists have found a species of crab that cultivates gardens of bacteria on its claws, then eats them.
