The Astacus erectus are sinister looking crayfish that roam in a secluded part of Black Isle. The only way to get to them is to pass through a tunnel at the entrance of the mine shaft. One can also be found in the entrance of the Volcano's Treasure. Though they may look intimidating, they are actually docile creatures that pay no attention to Jade when she approaches them.

Like their name suggests, these crayfish walk on two legs and possess long spiked forelegs. They vary in size, but usually reach a height up to a grown human's waist.

These creatures are based on the real-life crayfish and praying mantis.
