In an upcoming paper for the journal Aquatic Mammals, a pair of scientists detail a series of interactions between an adult bottlenose dolphin with scoliosis - "highly pronounced curvature of the spine " - and a group of sperm whales in the Azores. The scientists describe their research as the first time sperm whales have been observed interacting in a non-aggressive way with a member of a different species.
In other words: They repeatedly spotted a dolphin with a messed up back hanging out with a group of sperm whales.
The paper's authors, Alexander Wilson and Jens Krause, write that the whales treated the dolphin as a "conspecific" - a member of the same species - "at times both permitting and initiating physical contact." They also say that the interactions went beyond "simple tolerance."
