Thalassarche chlororhynchos chlororhynchos
The Atlantic yellow-nosed albatross (Thalassarche chlororhynchos) is a large seabird in the albatross family. The scientific name is from Ancient Greek. Thalassarche is from thalassa, "sea" and arkhe, "command", and chlororhynchos is from khloros, "yellow", and rhunkhos, "bill".
This small mollymawk was once considered conspecific with the Indian yellow-nosed albatross and known as the yellow-nosed albatross. Some authorities still consider these taxa to be conspecific, such as the Clements checklist and the SACC, which recognizes that a proposal is needed.
Mollymawks are a type of albatross that belong to Diomedeidae family and come from the Procellariiformes order, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights. They also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.
