I was vegetarian for 7 years. But I uh…
cheated. Every now and then I would have like just one crab cake. They don’t count right?
It’s not like they can feel pain. Oh shoot. Apparently. They can. Noooooooooo! Hey guys Julia here for DNews We humans like to think pretty highly of ourselves.
We put ourselves on the top of the totem pole of the animal kingdom. We’ve got our big
brains and our fancy thumbs for texting. Every animal is beneath us. And for a long time
we thought we could just use any animal how we wanted to. It didn’t matter. For a long time we didn’t think they could
feel pain! Scientists for hundreds of years though that animals couldn’t feel, they
just simply reacted mechanically. I mean compared to our complex nervous systems it made sense.
But crab’s nervous systems do have their own complexity. Well a study published in the journal Biology
Bulletin found that crabs and other crustaceans “have life spans of many years and a brain
that, in size and complexity, lies somewhere between the octopus and insects” . They have a small brain of sorts right behind
the eyes. Their main brains are more complex than you might think. They have three ganglia
that have fused together to form a single brain. They also smaller brains also called
ganglia for each section of their bodies. These smaller brains mean a quicker response
from stimuli in the environment; the nerve signal doesn’t have to travel as far. So what happens when those nerves get stimulated?
Do they feel pain?. A recent small study published in the journal Biology Letters found that
crabs physically react to a pain stimulus. The researchers subjected 20 crabs European
shore crabs to electrical shock. Most, of the crabs started walking around in their
tanks and a few tried to climb out. While some the control group of crabs who did get
shocked started to walk but 6 did nothing. But most telling was when the researchers
tested their “blood” or their their haemolymph. It had three times the amount of lactic acid.
A clear physiological sign of stress. Another study published in the journal Animal
Behavior found that hermit crabs feel pain and specifically avoid it. Crabs given electric
shocks were more likely to leave their shell and to seek out another shell without the
shocks. So it’s clear they feel something and avoid it when possible. And according
to another study published in the journal Applied Animal Behavior Science they also
limp or show other protective behaviors called “pain guarding” and they even show fewer
responses to negative or supposedly painful events. And so that fits a definition of “suffering
pain” as described by Temple Grandin in a study published in the journal Emerging
Concepts and Strategies in Veterinary Medicine, in which she found mammals from humans to
the lowly rat suffer from pain. She even found evidence that birds, reptiles and fish feel
pain too. She can tell when an animal suffers from pain based on certain behaviors, like
pain guarding and seeking analgesics, which reduce pain. Pain guarding is like when you
dog hurts its paw and so won’t put any weight on it anymore or Or if they were hurt in a
specific place, they learn to avoid that place in the future. And a wide range of animals perform this kind
of behavior. Even chickens, when their beaks are trimmed, peck less than usual. Other studies
on mammals and birds and even fish found that when the animals were given analgesics like
morphine, those pain guarding behaviors stopped. Which is bad news for me and my new pescetarian
lifestyle. Ugh but shrimp just taste so good. Guess I should go whine about it somewhere
on the internet. Maybe I’ll start a website like iwillnevereatshrimpagain.com which is
available on domain.com. No domain extension will help you tell your
