Gyratrix hermaphroditus is a species of rhabdocoel flatworm in the family Polycystididae. [2]
The animal is 1 to 1.5 mm long, transparent and colorless. It possesses a proboscis at the anterior end and a sharply pointed stylet. [3]
It was described by Christian Gottfried Ehrenberg in 1831. [2] Gyratrix hermaphroditus represents a species complex. [4]
Members of the species complex occur in both marine and inland water habitats. [4]
It is known to feed on copepods and cladocerans. [5]
The South American sea lion, also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the western and southeastern coasts of South America. It is the only member of the genus Otaria. The species is highly sexually dimorphic. Males have a large head and prominent mane. They mainly feed on fish and cephalopods and haul out on sand, gravel, rocky, or pebble beaches. In most populations, breeding males are both territorial and harem holding; they establish territories first and then try to herd females into them. The overall population of the species is considered stable, estimated at 265,000 animals.
River stingrays or freshwater stingrays are Neotropical freshwater fishes of the family Potamotrygonidae in the order Myliobatiformes, one of the four orders of batoids, cartilaginous fishes related to sharks. They are found in rivers in tropical and subtropical South America. A single marine genus, Styracura, of the tropical West Atlantic and East Pacific are also part of Potamotrygonidae. They are generally brownish, greyish or black, often with a mottled, speckled or spotted pattern, have disc widths ranging from 31 to 200 centimetres (1.0–6.6 ft) and venomous tail stingers. River stingrays feed on a wide range of smaller animals and the females give birth to live young. There are more than 35 species in five genera.
