Find the crab king

I drew this on the water side of a lake that is part salt and fresh water ("brak"), so the plants on the shore are normal fresh water plants, but there were mudworms and crabs in the water. While I was drawing this a huge crab came by. It's carapax was covered with seaweed, trailing behind him like a robe. He looked kingly indeed.

The ants that walked over my paper are also included.

Sadly I didn't get to finish it, through lack of time. Oh and the scanner butchered the colours. The yellow is supposed to be more greenish, since the water was really green, more than blue.
