If this is true imagine how much more this applies to fish with a more elaborate nervous system.

Measurements show that crabs can process pain

Researchers from the University of Gothenburg are the first to prove that painful stimuli are sent to the brain of shore crabs, providing more evidence for pain in crustaceans. EEG-style measurements show clear neural reactions in the crustacean's brain during mechanical or chemical stimulation.

Low-status cichlid fish show higher brain oxidative stress, which is linked to poorer mental health in humans

Social stress is bad for your brain. It's a prime suspect in the accumulation of oxidative stress in the brain, which is believed to contribute to mental health and neurodegenerative disorders—but the mechanisms that turn social stress into oxidative stress, and how social status affects this...

Why wouldn't other types of animals feel pain? When I was younger and fished with worms and grasshoppers I always thought that they felt pain when put on the hook, one of the reasons I preferred not to fish with live bait. Pain is necessary to avoid doing things that potentially injure the body. I remember old timers telling me that fish don't feel pain, I didn't believe it then and I don't believe that now. There seems to be a lot of research on animal's pain sensitivities now, but it seems like common sense to me.

I agree. But it is only recently that the nerves that carry the pain signal were identified in invertebrates.

The research is recent, but the nerves are there. I think a lot of it is we truly didn't want to know, so we made up myths to cover. I've read fishermen who still argue fish don't feel pain because for the nerve stimulus to be pain, you have to know it's pain.

Uh huh. Yeah right.

There are still people who talk about lower or higher animals. As a species, we can be slow learners.
