Field Report Summary

Physical Description

Large, spider-like creature, about the size of a small dog. Possesses eight hairy legs and a segmented body. Instead of a standard abdomen, it has a broad, flat, paddle-shaped structure covered in coarse, brown fur, resembling a beaver's tail. Powerful mandibles capable of gnawing through wood. Spinnerets produce silk used to bind branches together to create dams and nests.

Habitat

Temperate forests near rivers and streams

Dietary Behavior

Consumes tree bark, leaves, and insects trapped in its webs.

Evolutionary Origin

A controversial experiment in genetic splicing went wrong, fusing the DNA of a beaver and a large, web-spinning spider.

Behavioral Notes

Constructs elaborate dams made of interwoven branches and silk, creating water reservoirs perfect for trapping prey.
