Giant axons
WebJan 9, 2007 · Giant axons are found in circuits throughout most of the more advanced bilateria, including those mediating rapid withdrawal of tube worms, escape jetting of squid, tail flip responses of lobsters and … WebThe giant axon of the squid is the largest known nerve cell in the animal kingdom. They can be up to 1mm in diameter and almost a metre long. The giant axons of the North Atlantic squid Loligo pealeii, are 50 times the diameter of axons in the common crab and 1,000 times those found in humans.
