Cratera (flatworm)
''Cratera'' is a genus of land planarians found in 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. Etymology The name ''Cratera'' is derived from the Latin word ''crater'' and refers to the cavity in the penis that resembles a volcanic crater. Species There are 24 species assigned to the genus ''Cratera'': *'' Cratera anamariae'' Carbayo & Almeida, 2015 *'' Cratera arucuia'' Lago-Barcia & Carbayo, 2018 *'' Cratera assu'' A ...

Cratera Tui
A krater or crater ( grc-gre, , ''kratēr'', literally "mixing vessel") was a large two-handled shape of vase in Ancient Greek pottery and metalwork, mostly used for the mixing of wine with water. Form and function At a Greek symposium, kraters were placed in the center of the room. They were quite large, so they were not easily portable when filled. Thus, the wine-water mixture would be withdrawn from the krater with other vessels, such as a ''kyathos'' (pl. ''kyathoi''), an ''amphora'' (pl. ''amphorai''), or a ''kylix'' (pl. ''kylikes''). In fact, Homer's '' Odyssey'' describes a steward drawing wine from a krater at a banquet and then running to and fro pouring the wine into guests' drinking cups. The modern Greek word now used for undiluted wine, ''krasi'' ( κρασί), originates from the ''krasis'' (''κράσις'', i.e., mixing) of wine and water in kraters. Pottery kraters were glazed on the interior to make the surface of the clay more impervious for holding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
