What level of pain do fish feel? That, too, is unknown. Zangroniz said studies only use a few species of fish and don't represent the more than 30,000 fish species that exist.
There have been numerous studies of learning and memory using nociceptors in the sea hare, Aplysia. [18] [19] [20] Many of these have focused on mechanosensory neurons innervating the siphon and having their somata (bulbous end) in the abdominal ganglion (LE cells). These LE cells display increasing discharge to increasing pressures, with ...

[1] Insects play many roles in culture including their direct use as food, [2] in medicine, [3] for dyestuffs, [4] and in science, where the common fruit fly Drosophila melanogaster serves as a model organism for work in genetics and developmental biology.
The fast and vicious stomatopods can also live in coral reefs or rock crevices. Depending on the specific mantis shrimp species, these marine critters can be active during the day or live nocturnally.
