The floating thickets of treelike seaweed provide habitat for a plethora of marine life, including seals, sea lions, whales, gulls, terns, and snowy egrets.

Sea otters must eat a quarter of their body weight each day to keep warm, and their appetites make them voracious consumers of spiny urchins, according to Rebecca Martone, a marine biologist at the Center for Ocean Solutions at Stanford University.
