This burly looking crayfish was found in the Columbia river in Oregon. Note the stout fore claws, no doubt a crayfish that spends it's life among heavy currents. This is a extremely rare specimen , as this is a blue morph of normally brown in color. and is the only one known alive.

Cherax Tenuimanus

Awesome looking specimen

Procambarus acutus

Otherwise known as the white river crayfish, the Procambarus acutus is widespread throughout the eastern united states. Locally here in New York state, they have been replacing the Orconectes immunis as the choice for bait farm crayfish. The one advantage is the females have the young in the fall, so when spring arrives, they are growing immediately instead of just hatching like the immunis. The acutus have better "bucket life" than the immunis, but they do have their downfalls too. They do cannibalize more frequently in heavy populations, and are a invasive type of crayfish, killing every immunis in a pond until the pond is completely taken over.
