In November of 1929, a strong earthquake rattled the Atlantic Ocean south of Newfoundland. On shore, the quake knocked down a few chimneys and blocked some roads, but otherwise caused little damage on its own.

On the ocean floor, though, it triggered a giant landslide. Perhaps 50 cubic miles of sediments tumbled down the slopes, creating a tsunami. The waves soon crashed into Newfoundland and Nova Scotia, killing about 30 people and damaging or destroying dozens of villages.

As utterly exhausting as it is to care for a newborn, most moms would never dream of abandoning their child. But what if it were a question of life and death…for the baby or the mom? That’s the dilemma that sea otter moms sometimes face when they can’t provide enough calories to meet their pups’ incredibly high energy demands. Researchers at a sea otter pup rehabilitation program measured the metabolic rates and daily caloric needs of sea otter pups and found the mothers need to provide more than 222,000 Calories to raise pups from birth to independence.
