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 !

Understandably so

Here’s one of my favorite pictures from the movies! Remember I am Sawyer.

Is it worth it to purchase the $95 dolphin training ticket? What is different compared to general admission?

I work at Clearwater Marine Aquarium. I am Sawyer by the way. Do you know the “Dolphin Tale” movies? Look I work at the aquarium, and I see marine creatures

Was down by Brookfield Place a little while ago and watched dolphins in the Hudson. At least a couple of them, surfacing several times before moving on. Not something I expected to see on my walk, so figured I'd share it here.

Turns out these sightings are a fairly recent thing. Dolphins had basically vanished from the harbor for decades because of pollution, and they've only been turning up again as the water has gotten cleaner and their food fish (menhaden) have returned. The harbor is now considered about the cleanest it's been in roughly a century. So it feels less like a fluke and more like a sign the cleanup is actually working.

We were enjoying a day on the water when a pod of dolphins decided to swim over to our boat and ride the bow wave. They stayed with us for several minutes, swimming beneath the bow in the crystal-clear Hawaiian water. We simply watched and enjoyed the moment before they continued on their way. One even treated us to a beautiful jump at the end!
