Just like humans, dolphins have social networks
They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute (HBOI) ...
Scientists uncover genetic similarities between bats and dolphins
The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research led by ...
Solomon Islands dolphins pay heavy price for teeth
Residents of the tiny village of Fanalei in the Solomon Islands killed more than 1,600 dolphins in 2013 for their teeth, a local currency and popular adornment, researchers said Wednesday.

New study finds dolphins produce sounds in a similar way to humans
Worm seeks worm: Researchers find chemical cues driving aggregation in nematodes
(PhysOrg.com) -- Scientists have long seen evidence of social behavior among many species of animals, both on the earth and in the sea. Dolphins frolic together, lions live in packs, and hornets construct ...
Killer whales living with bottlenose dolphins demonstrate cross-species vocal learning
From barks to gobbles, the sounds that most animals use to communicate are innate, not learned. However, a few species, including humans, can imitate new sounds and use them in appropriate social contexts. ...
