PUFFINUS
Puffinus
Puffinus is a genus of seabirds in the order Procellariiformes. It comprises about 20 small to medium-sized shearwaters. Two other shearwater genera are named: Calonectris, which comprises three large shearwaters, and Procellaria with another four large species. The latter are usually called 'petrels', although they are thought to be more closely related to the shearwaters than to the other petrels. Despite the resemblance in the name, the puffins are auks, and completely unrelated to the shearwaters in the genus Puffinus; the genus name Puffinus is actually a New Latin loanword based on the English "puffin".The above text is a snippet from Wikipedia: Puffinus
