Snapping Turtles & Duckweed
Duckweed (Wolfia sp.), a free-floating aquatic plant that possesses flowers which are said to be the smallest flowers in the world, is coating our mystery creature. The presence of this plant can indicate that there are too many nutrients in the water, especially nitrate and phosphate. On the plus side, Duckweed provides waterfowl, juvenile fish and other wildlife (including humans in Southeast Asia) with a protein-rich (40%) food.
Under this green coating is a Snapping Turtle, one of the largest freshwater turtles in North America. Most often encountered in June, when females leave their ponds to lay eggs, Snapping Turtles are infrequently observed at other times of the year. This is primarily due to their crepuscular and nocturnal habits as well as their tendency to spend a lot of time under water feeding on plants, insects, fish, frogs, small turtles, young waterfowl, and crayfish.
Found in most ponds, marshes, streams and rivers, Snapping Turtles are not aggressive towards humans. Their size is impressive (a full-grown Snapping Turtle’s top shell, or carapace, can measure up to 20 inches in length) but they shy away from human disturbance. Miniature versions with one-inch long carapaces can be seen this month as the young Snappers crawl up out of their subterranean nests after hatching from eggs laid in June and head for the nearest water.
