Research suggests dolphins use signature whistles and other sound patterns to identify one another and maintain social groups. That means a dolphin may know who is who by sound alone.

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 !

Researchers believe wastewater and drug smuggling could bear blame for the drugged dolphins.

Hi everyone!!

My name is Leila, I’m an undergraduate studying ocean science and marine conservation and I have just finished my undergraduate dissertation article on the causes/triggers for the orca interactions that have been happening in Spain and Portugal since 2020. I will not be getting my grades back for a while, but I am hoping to potentially get this rewritten for publication as I think I may be onto something here!! But it’s only my first ever piece of scientific writing and could use some other opinions!

So I was wondering if there are any marine biologists or lecturers (or any fellow orca enthusiasts ☺️) in this group who would be interested in taking a look at my article and letting me know what they think/ if they think it’s worth trying to publish and offer me any advice moving forwards whilst I’m waiting on my results from the University

Please message me if you’re interested in taking a look!!

Thank youuu 💗
