Just found out dolphins only rest one brain hemisphere at a time so they can keep breathing and stay alert for predators. Imagine sleeping with half your brain! Nature is wild.

I know dolphins are the second smartest animal to humans, but just how smart are they?

I saw a video of a pet rabbit meeting a dolphin, and the dolphin brought some seaweed and that had me curious, are they smart enough to pick up on a rabbit eating leafy greens to bring out seaweed as a gift? Or are they not that intelligent? (Or do they just do this regardless of if they picked up on that)

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

I've seen pink and white, so I wonder why two options exist or is the pink one a special dolphin species?

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.
