Brown pelican, winter adult breeding plumage, showing bright red gular pouch and dark brown hindneck plumage of breeding adults. This large seabird has a wingspan over 7 feet wide. The California race of the brown pelican holds endangered species status, due largely to predation in the early 1900s and to decades of poor reproduction caused by DDT poisoning.

Great white shark, research identification photograph. A great white shark is countershaded, with a dark gray dorsal color and light gray to white underside, making it more difficult for the shark's prey to see it as approaches from above or below in the water column. The particular undulations of the countershading line along its side, where gray meets white, is unique to each shark and helps researchers to identify individual sharks in capture-recapture studies. Guadalupe Island is host to a relatively large population of great white sharks who, through a history of video and photographs showing their countershading lines, are the subject of an ongoing study of shark behaviour, migration and population size.
Species: Great white shark, Carcharodon carcharias
Location: Guadalupe Island (Isla Guadalupe), Baja California, Mexico

White southern right whale calf underwater, Eubalaena australis. About five per cent of southern right whales are born white due to a condition known as grey morphism and will gradually turn dark as they age. They are not albino (which is a complete lack of pigmentation). Sometimes referred to as "brindled", the white coloration is a recessive genetic trait and only lasts a few months. Typically, but not always, white calves will become much darker as they mature but will still be somewhat lighter than normal even as adults. By permission of the Government of Argentina, Chubut, permit # 51 / 2025-SsCyA.
