animal partnership...?

Question

The hermit crab pairs up with which sea animal? I really saw a crocodile allowed birds as company to remove the leeches in its gum, and what does hermit crab do with its company?

Answer 1

Sponges can grow on marine hermit crab shells. These sponges start out as a thin covering on the snail shell, and then expand out until it can look like the hermit crab is actually living in the sponge. Some crabs find sponges and scrape away a hole that they then crawl into and "wear" like a shell.

All kinds of things can settle on hermit crab shells. Most commonly, algae (green or brown slimy stuff) grows on hermit crab shells. Algae aren't plants, but they're often green and might look like plant life. I
suppose sea creatures can stick to hermit crab shells too, but that sounds to me more like something a decorator crab would have growing on itself.

Decorator crabs don't have a snail-looking shell as a house but sponges, anemones, and other marine critters adhere, or stick directly to the carapace (top surface of the EXO of the crab). There are little hooked things called setae on decorator crabs' carapaces where foreign objects (marine critters) can attach. Decorator crabs can get all kinds of things growing on themselves, so you can see how their name fits them just like a hermit crab's shell fits the crab!Marine hermit crabs get all kinds of things growing on their shells, although mostly they get green and brown algae and the occasional anemone or other sea creature. They wouldn't get an octopus or a starfish growing on their backs though! Imagine how heavy that would
get for the crab.

Answer 2

SEA Anemones are placed on top of hermit's shell, so crab gets protection prom stingy anemone, a cnidarian, and it gets food as crabs are not such clean eaters and some of leftovers drift near its mouth and gets food easier than without a crab.
