Deformed, lonely dolphin adopted by friendly sperm whales


A deformed and lonely dolphin was adopted by a group of sperm whales in the Atlantic.

Researchers in Germany studying the whales off the Azores, found the unlikely dolphin swimming with the whales.

Apparently the deformed dolphin had been rejected by its own kind and the sperm whales may have felt bad for it.

Sperm whales are not typically known to be open to other species, reported National Geographic News.

Researchers said the adult male bottlenose dolphin had a spinal curvature that made his back an "S" shape - rather inconvenient for swimming in a straight line.

Science Recorder said that a lack of natural predators in the region may rule out the dolphin's use of the whales as a means of protection.

Rather, the curved mammal have just not been able to catch up with his own kind while swimming.

The whales could offer a more comfortable pace.

"Initially, we thought it was a very unusual interaction as sperm whales are not known to show non-aggressive behaviors to other species of cetaceans, however at this point we thought it might just be a one-off unusual interaction," study co-author Alexander Wilson told

"When some time afterwards we saw the same dolphin still interacting with the same or other sperm whales, we thought there must be some underlying mechanism...beyond the animals simply being in the same place at the same time."

Bottlenose dolphins have been known to bother and harass the whales and their offspring.

Seems like all is forgiven.
