He’s gettin’ big and able to stand on his own two feet. His latest video from last week, with Siku now aged 42 weeks (and 185 pounds!), is on Explore.org. Siku will live 25-30 years, and grow to weigh 900 to 1,600 lbs. “These powerful predators typically prey on seals. In search of this quarry they frequent areas of shifting, cracking ice where seals may surface to breathe air. They also stalk ice edges and breathing holes. If the opportunity presents itself, polar bears will also consume carcasses, such as those of dead whales” (National Geographic).
That should help put on the pounds! See more of our growing baby boy Siku here on the live cam!
