I posted some time ago about a study suggesting that crustaceans may feel “pain”. It is obviously very difficult to assess what this means outside of humans, but there is a new follow-up study being discussed in the science news that adds a little more insight. Here are some links:
Crabs Not Only Suffer Pain, But Retain Memory Of It
Crabs’ memory of pain confirmed by Queen’s academic
The actual paper.
I always thought that it was odd that people just assumed that decapods don’t experience pain. I like clever experiments like this.
Too bad Queens is have to make such deep cuts.
