Description:

Also known as Land planarians. Land planarians are soft, bilaterally symmetric, acoelomate, dorsally-ventrally flattened worms. They lack a respiratory and circulatory system, a skeleton, and an anus. Heads of many land planarians are expanded lunate or tapering to a blunt point. Eyespots may be present on the head.

Habitat:

rooted plants

Notes:

Just happening.. after flash rain... Colors of Florida species range from greenish-grey to brown with dark narrow stripes on the dorsal side. A mouth, which also serves as an anus, is present near mid-body on the ventral surface. A protrusible muscular plicate pharynx serves as a feeding organ and is attached to a three-branched intestine. The space between organs is filled with parenchyma. Circular and longitudinal muscles are present. A cerebral ganglion serves as a brain, innervating a ladder-shaped nervous system. Excretion of fluid wastes is accomplished with a primitive proto-nephridial system.
