This bizarre sea creature isn’t what it first seems (pics+vid)

At first glance, this creature appears to be a grotesque blob of matter with a disturbing, slimy proboscis.

But, it is actually one of nature’s most cunning survival tactics at work.

Creature A is a sea cucumber that spends its days eating sand, before excreting it back out, while creature B is a pearl fish that has found shelter inside the sea cucumber to escape its enemies.
