Dolphins that hunt with sponges may show traces of culture in their gene activity, study finds

In Shark Bay, Australia, the dolphins put marine sponges over their snouts while feeling along the seafloor for fish. The habit may go hand in hand with subtle biological differences. What's happening?

Dolphins that engage in "sponging" carry epigenomic signatures distinct from those seen in other dolphins in the same population, according to ScienceAlert, which reported on a new analysis of Shark Bay's Indo-Pacific bottlenose dolphins.

The epigenome is the set of reversible chemical marks that can affect gene activity without changing the DNA sequence itself !
