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

Male Brandt's Cormorant Skypointing, Courtship Display, Breeding Plumage with blue throat and white pin-feathers, La Jolla. Skypointing is an interesting courtship behavior that many birds practice. Among Brandt's Cormorants the male performs this, likely as a way of attracting a mate to the nest he has built by showing off his striking blue throat. He tips his head backward showing off his striking blue throat, and partially raises his wings. Seen here on seacliffs above the ocean, where the fading light of late afternoon just illuminates his head and wings.
Species: Brandt's cormorant, Phalacrocorax penicillatus
