Common Hermit Crab (Pagurus bernhardus)

Also known as the soldier crab, the common hermit crab is a species of pagurid hermit crab which is distributed along most of Europe’s Atlantic coasts. Common hermit crabs are typically seen in pools on the upper to lower shore regions in rock/tide pools. Common hermit crabs chiefly detritivores but they will also scavenge and filter feed if necessary. In typical hermit crab fashion P. bernhardus will use the shells of gastropod species, like Littorina sp. and Buccinum sp. for protection.

The hitchhiker’s guide to the lobster’s face
What has a mouth that falls off, lives on an animal's facial hair, and is pregnant before it's even born? While it sounds like the the beginning of a terrible joke, such a creature does exist, and they're just as strange as you'd expect them to be.

With three distinctive forms and two different reproduction methods, these tiny creatures run an elaborate plan to populate a lobster’s face.
