|Albatrosses, members of the family Diomedeidae, represent a small group of large tube-nosed petrels, with 21 recognised species. They include the largest seabirds, with wingspans measuring over 3 m and have powerful beaks for capturing prey at the sea surface.|
They are adapted for foraging for long periods over the open ocean and are estimated to spend over 80% of their lives at sea, where they are capable of travelling long distances at high speed, reaching burst velocities of 130-140 km/h. They can cover up to 1800 km in a day during migration. Some albatrosses range widely over pelagic ocean, while others forage for food comparatively close to land over areas of continental shelf. Albatross are primarily surface feeders, with some shallow plunging. Their diet is known to include squid, krill, and fish, with some crustaceans and salps, although the diet of most species has been poorly researched.
