I saw a study on Integumentary sense organs on the National Geographic channel awhile back. These Dermal sensory receptor pits seem to be more "used" in the juveniles. The exact use of these are still unknown i think. As i go to the Everglades allot and take photographs of gators , i noticed while i lure them close to the bank with a light splash of my snake hook that the smaller gators come almost immediately,the larger ones 9ft plus dont seem to come at all in some cases. The study they did was to take a liquid plastic and paint it on these pits and take vasilene andinject it into the ears of the gators then send pulses into the water at night to see if they responded. The smaller ones didnt move one bit with the plastic and vasiline aswell as the adult. As soon as the plasticwas taken off the
sensory pits they came over to the pulses immediatly, but the adult didnt move either way. I have just got very interested in these pits. I havnt seen any further research on them anywhere on the internet or anywhere that i could find. Would anybody know any new information on these or where to find them. Thanks, jason
