Crabs are brave guys. You can hardly come across a more audacious species at the bottom of the sea. They are ready to fight for a reason and for no reason, even for the smallest thing. Beware their pincers. You cannot miss them because they are usually the first thing you will notice. If it grabs you by the finger, this is not good, believe me. Big crabs are called by different names in different parts of the Bulgarian Black Sea coast. You may hear some very funny labels.
The other species are smaller and, it seems to me, a little bit better behaved. That is, they do not spend too much time at the same place. If you go into the see to pick some rapa whelks for an appetizer, do not put them in your swimming
suit, because you might go home with a rapa whelk shell inhabited by a hermit crab. And it has pincers, and yet classical ones – the one is bigger than the other ... I have a friend who can tell you more about this.
Otherwise, crabs are among the most interesting sea inhabitants and do a lot of crazy stuff. There are punk crabs with seaweed on their heads, I have seen a crab who left his home and family and went riding a huge jelly-fish, and some crabs go out on the shore at night to look for the light of the torch. And they are delicious, as well. With beer or a bottle of white wine.
