| On trees up to 10 feet above ground, flood plain of Little Black Creek, County Road 
			220 0.2 miles NW of Knight Boxx Road, Clay 
			County, Florida, 07/10/2021. Observations at this location over the 
			years indicated that the species routinely climbed trees to avoid 
			drowning during times that their habitat was inundated by flood 
			water. While that is in fact true, recent observations strongly 
			suggest that the climbing survival strategy is not triggered by the 
			actual presence of flood waters but instead is triggered 
			instinctively by prolonged heavy rain. During a visit to the flood plain on 7/10/2021 a total of nine Mesodon were found sheltering in trees up to about ten feet above ground and there was no evidence of flooding despite recent prolonged heavy rain and the passing of a tropical storm. One of the nine was found in a tree in an area not subject to flooding. During drier periods the snails at this location live buried in leaf litter at the base of trees. |
