Just like fish, blue crabs breathe using gills. 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.

Like fishes, crabs use their gills to absorb oxygen from water. Some crabs live almost exclusively on land and most can survive out of water for notable stretches of time. As long as a crab’s gills stay damp, oxygen will diffuse from the atmosphere into the water on their gills.

Land Crabs Some crabs, like coconut crabs and land hermit crabs, are terrestrial and breathe well without water, although they still need to keep their gills moist. As long as their gills stay moist, these crabs can spend their lives out of the water. But if they were submerged in water, they would die.

As terrestrial crabs, coconut crabs have air-breathing organs that allow them to spend most of their lives out of water—hold them under water long enough and the crabs will actually drown.

Just like Stump Snail, having bees that have a high attack and/or specialized in attacking, such as Rage Bee, Lion Bee, and Vicious Bee will be necessary to quickly defeat the Coconut Crab. Be sure to also have Music Bees and other bees who produce focus tokens, as they will also play a major role as well.

Coconut crab runs off with family’s MACHETE That’s brilliant.” Max Orchard, the former chief ranger of Christmas Island National Park, says the crab’s thieving is triggered by the pursuit of food. “They come across things they don’t know but they check them out as they may be able to eat them,” he explains.

While the coconut crab itself is not innately poisonous, it may become so depending on its diet, and cases of coconut crab poisoning have occurred. For instance, consumption of the sea mango, Cerbera manghas, by the coconut crab may make the coconut crab toxic due to the presence of cardiac cardenolides.

All are decapod crustaceans (order Decapoda, class Crustacea). Adult coconut crabs are about 1 metre (40 inches) from leg tip to leg tip and weigh about 4.5 kg (10 pounds). The full-grown adult ranges in colouring from light violet to brown and deep purple. Young adults are brown, with black stripes on their legs.

Coconut crab claws are substantially stronger than human hands, which have an average grip strength of about 300 newtons. They also eat the remains of dead animals, using their claws to break the bones.

The coconut crab — sometimes called a robber crab — boasts powerful pincers, which are some of the most dangerous weapons in the animal kingdom. Experts say a pinch from this crab can rival a lion’s bite. So there’s no question that they can do some terrifying things with those claws.
