Evidence suggests that sloths grow algae in their fur and then eat it. This algae-farming is thought to be aided by moths that live in the fur, and whose growth the sloth actively promotes.

Why do these sluggish mammals go on such a long and potentially dangerous journey instead of just letting it fly from the treetops? Scientists now believe the answer has to do …

Five completely separate groups of crustaceans independently evolved into what we commonly refer to as “crabs.” This phenomenon is called “carcinization.”

Evolution of crabs – history and deconstruction of a prime example of convergence Compared with the elongate bodies of shrimps or lobsters, crabs are characterised by a compact body organisation with a depressed, short carapace and a ventrally folded pleon. The evolutionary transformation from a lobster-like crustacean towards a crab is called ‘carcinization’ and has …
