Crabs don't urinate in the typical sense. Waste from nitrogen metabolism is not concentrated into a urinary bladder like mammals; aquatic crustaceans are able to dissolve wastes directly into the water through their gills. This is important since nitrogenous waste mostly takes the form of ammonia (not urea) which is highly toxic. Studies indicate that energy expenditures for physical processes at the gills focus on uptake of oxygen, which is sparsely dissolved in water, not the elimination of wastes like ammonia, ammonium, or carbon dioxide. Because of the relative ease of elimination of the highly soluble ammonia and the more urgent need for oxygen uptake at the gills, the nitrogenous waste excretion process can be fairly described as 'passive'.
Every form of life excretes waste products. It is part of the definition of "life".
Every living creature excretes somehow. So, yes, crabs can excrete.
thru their pee pee
yes i think
Hermit crabs do excrete waste, they pee so little, you dont notice it, and they store it in their shells and scoop it out, along with excrement.
Sea pee u
Herbivorous sea crabs eat algae and seaweed.
Yes, people pee in the see. Also animals that live in the sea.
sea birds, fish, octopuses, crabs, and other hermit crabs
sea
answer
Yes it does they are sea otters, crabs, and a type of fish.Yes it does they are sea otters, crabs, and a type of fish.
I guess they could, but this is a LOT of kinds of jellyfish, crabs, and sea turtles.
they can live on both. Crabs live on land and sea like hermit crabs
