When Speak to in between the integument as well as bordering sea h2o Remedy is blocked, crocodiles are found to get rid of their ability to discriminate salinities. It's been proposed which the flattening from the sensory organ in hyperosmotic sea drinking water is sensed from the animal as "touch", but interpreted as chemical information about its environment.[84] This may very well be why in alligators They can be absent on the remainder of the physique.[85]
