My ID is just a reasonable assumption, since having seen a member of crayfish, Astacidea of fitting size in Badlbach for short moments.
Now i know why this was my first observation of this crustacean animal - it is quick as a fish in water, hiding below stones for usual, and leaving its hiding-places in the dark as short as necessary.
So i guess to have seen stone crayfish, but can't exclude that it was any related species.
There was no chance to take imgs. of the animal.
This tiny hermit crab, less than an inch long in a dogwinkle shell, looks like it may be Pagurus granosimanus or Grainyhand Hermit. I've seen a lot of these on our beaches, but always the main color of the claws and legs is olive green with little turquoise spots. This one is so red! It does have orange antennae, a characteristic of the Grainyhand Hermit. Note there is a second hermit crab with the identical coloration, but smaller, in the lower right. I think it may be in a Black Turban shell.
Hole near my neighbor's pond. Appeared to have been opened up by pushing out the mud from below. Also there is a raccoon track in the mud. It was smooth inside the hole, so I do not think the raccoon dug it out. Is this a crayfish hole?
The decapods or Decapoda (literally "ten-footed") are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with approximately 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (c. 3000 species) and Anomura (including hermit crabs, porcelain crabs, squat lobsters: (c. 2500 species), making up the bulk...
