| synonyms = Diomedea nigripes They also have a salt gland that is situated above the nasal passage that helps desalinate their bodies, to compensate for the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose. The specific epithet of nigripes is derived from two Latin words, niger meaning "black", and pes meaning "foot".

The black footed albatross is a small member of the albatross family (while still large compared to most other seabirds) that has almost all black plumage. Some adults show white undertail coverts, and all adults have white markings around the base of the beak and below the eye. As the birds age they acquire more white at the base of the beak. Its beak and feet are also all dark. They have only the one plumage. They measure , have a wingspan of , and weigh Males, at an average weight of are larger than females, at an average of (such as Laysan, Midway, and the French Frigate Shoals). Small populations can be found on the Japanese islands of Tori Shima, Bonin, and Senkaku, and off the Mexican coast, primarily on Isla Guadalupe. They are extirpated from the Iwo Jima, Agrihan, Taongi Atoll, Marcus Island, Wake Island, and Johnston Island. Nests are simple depressions scraped in the sand, squid and to a lesser extent crustaceans. It will also consume floating debris, including plastics.

The black footed albatross is considered near threatened by the IUCN, because it is taken incidentally by longline fishing. An estimated 4,000 are taken every year, based on the number taken in 1990; other estimates put the number at 8,000, although more recent numbers are at around 6,150 per year with the majority of deaths from Taiwanese and Japanese fishing fleets. It is also vulnerable to oil and ingestion of floating plastics, which reduces the space in the stomach available for food to be brought to the chick. Finally volcanic eruptions on Torishima continues to be a threat. The black footed albatross has an occurrence range of and a breeding range of , with a population of 129,000 adult birds. Of these birds 24,000 pairs breed on Midway Atoll and 21,000 pairs breed on Laysan Island. Torishima has 1,218 pairs, the Bonin Islands have 23 pairs and there are about 400 pairs on offshore Mexican islands with 337 on Islas Guadalupe. All of these numbers come from estimates from 2005 to 2007. All of its nesting sites in the U. S. are protected, along with a buffer zone around these islands. Within this buffer zone longline fishing is outlawed. Almost 80% of the breeding population is counted or sampled each year and most fisheries utilize seabird bycatch prevention measures.
