Quick Summary

Loligo is a genus of squids, characterized by their somewhat flattened, cylindrical bodies. These squids belong to the family Loliginidae, which are elongated and cylindrical with a tapering body and partially retractable arms. Squids, in general, are marine animals with complex eyes and ten arms, two of which are specialized tentacles. They are found in both coastal and oceanic waters and can be swift swimmers or part of the plankton.123

Squids play a role in the marine food web, serving as food for animals like sperm whales and bony fishes, and are also consumed by humans. Their reproduction involves males depositing spermatophores into females, and egg-laying can occur communally, with eggs encased in gelatinous capsules. The incubation period for Loligo eggs is approximately 40 days.34

These sites have the advantage of being readily accessible for recording by electrodes—especially the squid synapse, which is large enough that electrodes can be inserted directly into the presynaptic terminal and postsynaptic fibre. In addition, only a single synapse is involved at these sites,…
