There’s no doubt that harp seal pups are perilously cute. But did you know that once they grow up, these seals migrate thousands of miles each year?

Named after the dark, harp-shaped patterns on the backs of adult seals, harp seals are widespread in the chilly waters of the North Atlantic and Arctic Oceans. They spend their summers far north, and then migrate south each winter to breed on the pack ice.

Disabled Killer Whale Survives with Help from Its Pod

In one of those incredible-but-true stories that makes you want to give the oceans a giant hug, a disabled killer whale missing two of its fins and unable to hunt to feed itself is able to survive through the help of its family. The young male killer whale, or orca, has no dorsal fin or right-side pectoral fin, leaving it unable to hunt and capture prey for itself. Instead of being abandoned or rejected by its pod and left to die, however, the killer whale appears to have been cared for and supported by the members of its pod, which share food with the young whale.

Sperm Whales Adopt Malformed Dolphin Into Their Group

Herman Melville’s Moby Dick may paint a picture of the sperm whale as a terrifying, ferocious creature that destroys ships and attacks the sailors on them, but modern research shows that sperm whales are compassionate and social creatures, dangerous only to the fish and squid that the giant whale feasts on for dinner, or to the orca whales that prey on sperm whale calves. A heartwarming and unusual recent discovery does even more to distinguish the sperm whale from its deadly reputation, as a group of sperm whales were observed “adopting” a bottlenose dolphin with a spinal malformation.


Behavioral ecologists Alexander Wilson and Jens Krause discovered this unique phenomenon when they set out to observe sperm whales off the island of Pico in the Azores in 2011. Upon arriving there, they discovered a whale group of adult sperm whales, several whale calves, and an adult male bottlenose dolphin. Over the next eight days, the pair observed the dolphin with the whales six more times, socializing and even nuzzling and rubbing members of the group. At times, the sperm whales seemed merely to tolerate the dolphin’s affection, while at others, they reciprocated. "It really looked like they had accepted the dolphin for whatever reason," Wilson reports to ScienceNOW. "They were being very sociable."
