How Sperm Whales Sleep

This is how sperm whales sleep, but Matt Kaplan at Nature has the story behind this incredible shot:

…in 2008, a team of researchers off the coast of northern Chile happened upon a pod of vertically bobbing sperm whales that seemed completely oblivious to its presence. Not a single whale responded to the team’s boat until one of them was accidentally nudged, at which point it awoke and fled, along with the rest of the group. The team’s findings suggest that, unlike other cetaceans, sperm whales appear to enter short, but periodic, bouts of sleep throughout the day — an observation that Kaplan says could hint that sperm-whales are actually “the least sleep-dependent mammals known.”

Kayaking with Whales in Redondo Beach

Youtube user oreoxxmiho: “The only thing bigger than that blue whale is that guy’s balls.”

“A whale lunge feeding right next to the Kayak, plus some underwater footage. While the lunge feed was heart pounding excitement, I found that seeing one undewater was relaxing and peaceful. Was an awesome day!”
