The polyps of two new gorgonia discovered, Tauroprimnoa austasensis and Digitogorgia kuekenthali, in the region of Austasen, in the Eastern Weddell Sea, and to the south-east of the Falklands and Isla Nueve (in Chilean Patagonia) respectively, are small and elongated, which is nothing special, but both species stand out for the number, shape and layout of the scales of calcium carbonate that cover the polyps, and for the type of ramification of the colonies.
"The Tauroprimnoa are characterized by being colonies in the shape of a brush, with simple branches and whose polyps arranged in whorls, have only four marginal scales. The rest of the polyp is covered by five longitudinal rows of scales. The sight is reminiscent of a bull, hence the name", Rebeca Zapata-Guardiola, main author of the study and researcher in the department for Physiology and Zoology at the US, describes to SINC.
The other four species discovered in the area of the South Georgia islands and in Atka bay in the Antarctic region –Thouarella bayeri, Thouarella sardana, Thouarella undulata, and Thouarella andeep- are made up of, like the others of their kind, eight rows of scales that cover the surface of the polyp.
