I stood with my feet buried in sand, staring at the ocean waves as they touched the beach. It was mid-October. To my untrained eye, the Monterey Bay shoreline looked like a child’s bubble bath. To California Fish and Wildlife scientists, it was a terrible déjà vu. Nine years ago, an algal bloom wreaked havoc—and…
For many years, I thought California sea otters were cute and cuddly. Who can resist watching them playing in the ocean, often with a baby otter alongside? Cute sea otter imagery is everywhere, from event logos to plush toys to bumper stickers, because we love them so much. Sea otters also help keep the ocean…
Last fall, our class visited the sea otter researchers at the Monterey Bay Aquarium. Sandeep summarized many neat tidbits about otters from that trip on this blog. Two items that really piqued my interest involved otter mortality. In California, many otters die from disease or shark bite. What’s going on? I tracked down the answer during…
The otters our class saw on our field trip to Monterey Bay were awfully cute. But I have to admit there was a piece of my former engineer’s heart that was touched, not by the furry faces, but by the antennas, radio transmitters, temperature and depth recorders, and GPS computers the scientists showed us. The sensors were…
1. Sea otters have the densest hair of any mammal – around 900,000 hairs per square inch (140,000 hairs/cm2)[1]. That’s more than 500X denser than the hair on the human scalp, which averages at 1600 hairs per square inch (250 hairs/cm2).[2] 2 Sea otters have individual preferences for prey. Some sea otters prefer to crunch…
When I hear that otters spend X percent of their time feeding (or some other behavior), how do scientists know that? Surely they don’t follow otters around to see what they do all day… As it turns out, that’s exactly what researchers do. So how do you follow a marine mammal around? What are the…
