Huge crayfish/crawdad scuttling scarily quickly along the bottom of a trout stream. Chonky. Wide and tall. A mini lobster. I looked on in awe and horror.

A photo of the claw of a NZ southern koura crayfish. The claw is covered in lots of pink blobs with tentacles. These are a kind of flatworm specialised at living on crayfish.

One of the highlights of my day was when William Harland, a talented ecology undergrad here at #LincolnUniversityNZ, stopped by my office to show me his photos of temnocephalid flatworms. These distinctive squat tentacled flatworms live in colonies on NZ's […]

I made a silly ✋

I saw what I thought was an eaten carcass of one of my new crayfish.
