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.

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

El Copulador, a well known male southern right whale in Argentina. El Copulador, "The Copulator", is a serious player in the southern right whale mating game. He was a white calf and, while most white calves darked to near-black as they age, El Copulador has retained a distinctly light coloration. He is often seen in mating and courtship groups and has likely successfully mated with many females over the years.
Species: Southern Right Whale, Eubalaena australis
Location: Puerto Piramides, Chubut, Argentina

Courting group of southern right whales, aerial photo. Mating may occur as a result of this courting and social behavior. The white whale seen here is a serious player named El Copulador (the copulator) and is often seen in mating and courting groups of southern right whales at Peninsula Valdes. His light coloration is an indication that he was a white calf, but he did not darken as he aged in the way most white southern right whale calves do.

Brown pelican preening, showing bright red gular pouch and dark brown hindneck plumage of breeding adults. After wiping its long beak on the uropygial gland near the base of its tail, the pelican spreads the preen oil on feathers about its body, helping to keep them water resistant, an important protection for a bird that spends much of its life diving in the ocean for prey.
