All crustaceans have a brain but the number and size of the neurons are what really comes into play along with the encoding of information. There isn't so mush as memory as there is neural inputs from smell (prey/food, salinity of water), pressure and temperature (water), neuron receptors to close claws on items. But so much of a brain that reasons or has logic processing? No. Everything a crab does is mostly by instinct and the neural pathways were formed to support those instincts. Crabs do possibly hear, but it is more the natural vs. unnatural frequencies that they respond to and their hearing is better underwater.

Always love it when one of your videos shows up in my feed.
I like your videos brother. I'm down in Deale MD, south of ya
Next time I come down from Western Maryland to visit family on the Eastern Shore would love to buy some crabs from ya!
I have heard the same thing about the crab nervous system but they have a rudimentary brain...limited capacity to think. More instinct than thinking.
Theres not enough crabs because you spent years wiping them out.
