Cratera is a genus of land planarians from South America.
Description
The genus Cratera is characterized by having a leaf-shaped body. Most species are between 3 and 7 cm long. The hundreds of eyes distributed along the body are monolobulated, i.e., simple and circular. The copulatory apparatus has a permanent conical penis occupying the entire male cavity. The final portion of the ejaculatory duct, the channel that guides sperm through the penis, has an expanded cavity that resembles a volcanic crater. It is very similar to the related genus Obama, the main difference being the presence of trilobulated eyes in the latter.[1]
Etymology
The name Cratera is derived from the Latin word crater and refers to the cavity in the penis that resembles a volcanic crater.
