A DAY IN THE WELL
SCUBA divers have witnessed the entire bottom waving with slimy leeches protruding from soft mud tunnels during the day. Biologists think the leeches remain near the dimly lit bottom to avoid being seen and eaten by the turtles that are often basking in the sun on logs and dense aquatic plants. Some also think that the leeches may feed on the tiny worms that slither through the soft bottom mud.
Within the dense aquatic vegetation around the Well, the highly
camouflaged stick-like water scorpion (pictured below) awaits
quietly on stems and foliage and occasionally grabs an
unsuspecting insect or amphipod that ventures too close to its
claw-like legs. Female water scorpions also use the stems of
aquatic plants to deposit their eggs. These cylindrical eggs
with two air-breathing appendages can be seen in the stem in the
Along the pathways around the Well, especially during the summer and fall, visitors will frequently encounter the beetles searching for food and, when harassed, these insects will take a protective stance with their posterior ends pointed upward ready to release a pungent spray to ward off potential enemies. Numerous damsel and dragonfly adults will also be seen flying along the shoreline of the Well in search of unsuspecting smaller aquatic insect prey.
