Physical characteristics

"External anatomy: Flatworm with irregular and variable color pattern characterized mainly by a cream background mottled with orange, and pink and purple-red dots concentrated medially forming an elongated blotch. The margin consists of purple and pink irregular spots and dots that are more concentrated on the tentacles making the tips a little darker. The ventral side is light violet. Pseudotentacles formed by simple folds of the anterior margin with few marginal eyes. Cerebral cluster made of about 30 eyespots. Presence of a broad folded pharynx. Internal anatomy: The male reproductive system consists of unbranched vas deferens, an elongated seminal vesicle connected to a short and coiled ejaculatory duct, a round prostatic vesicle, and a small stylet housed in a deep antrum. The female system has a deep and tubular female antrum with curved cement pouches and a short vagina directed backwards and surrounded by the cement gland."Author Bolanos Marcela, extract from http://polycladida.lifedesks.org/pages/3088
