Mangrove Periwinkle Snail
Littoraria angulifera is a common inhabitant of mangrove forests, mainly above the water line on trunks and prop roots of the Red Mangrove. They can also be found on the Black and White Mangroves at Green Key. They are a very colorful snail with brown, blue, white, and checkered forms found throughout the mangroves. I have seen a Limpkin feeding on them in the mangroves. It is reported that they have a sixth sense for the tide levels allowing them to drop their eggs at a high tide and also to go up mangrove trunks as the tide comes in.
