These cephalopods, who telegraph their moods by color changes and solve problems by using tools, have surprised me again and again.
And now it’s happened again. An octopus has astonished me.
This time, it’s a common octopus caught on camera in South African waters by a dive team for the documentary Blue Planet II, currently airing on BBC America in the United States.
The action is dramatic. A pyjama shark seizes the octopus. Just as the situation begins to look dire, the octopus stuffs the shark’s gills shut using its sinuous arms, making it impossible for the shark to breathe — until the shark releases it.
Migaloo is an albino humpback whale, usually sighted along the Australian coast, and occasionally in New Zealand waters. Migaloo was named by the Hervey Bay local aboriginal collective, and it means “white fella”. While several Humpback Whales have been spotted with almost 90% white pigment coverage, Migaloo is the only documented albino.

That was rather impressive
Dinoflagellates! These bizarre microorganisms are found all over the ocean, and occasionally freshwater lakes and ponds. Some are photosynthetic, some are predators, some are both! They are also the plankton responsible for toxic red tides.
The first two pictures show Pyrocystis dinoflagellates. These are closely related to the dinoflagellates that bioluminesce a bright blue along coastal waters. In the top picture, you can see a cell dividing its nucleus into two, as well as some sort of protective cyst in the lower right corner.
The 3rd picture is a bloom of Gymnodinium dinoflagellates, and the last picture is a close-up. See the nucleus?
More neat facts: some dinoflagellates have 215 billion base pairs in their genome. For comparison, the human genome is made up of about 3 billion base pairs! No one really knows why they have so much DNA, most of which is heavily modified and wrapped with re-purposed virus proteins.
The National Science Foundation (NSF)—the major funding agency for basic science—has canceled all grant review panels this week to comply with an executive order from the new administration. This is where independent panels of scientists discuss grant proposals they’ve reviewed for scientific merit and recommend which projects get funded to NSF project managers. A LOT of work goes into setting up and scheduling grant reviews. It will take time to reschedule these panels, delaying key decisions for many promising projects. This will wreak havoc on science grant funding for months to come.
Put simply, this action along with the halting of NIH-funded grants are blatant and reckless political attacks on science, from an administration that seeks blinding loyalty.
This is how we go from single cells to people.
Stunning Footage of Sperm Whales Attempting to Communicate With Freedivers Using Clicking Noises
Each summer, researchers conduct expeditions in our West Coast sanctuaries as part of the ACCESS conservation partnership. Researchers get to see creatures big and small when conducting surveys in places like Greater Farallones National Marine Sanctuary!
Marine Life of the Maritime Provinces, Canada
After months of work and waiting, here is at long last the full MARS commission. MARS (Marine Animal Response Society) is active in the Maritime Provinces of Canada, and is called upon whenever a marine creature is found dead or in distress. These illustrations will be used to educate their volunteers and assist in making species identifications during strandings or at sea.
With 42 separate illustrations, this is my largest project to date - quite a load of work! But it was an absolute pleasure to do. I got to paint animals I have never painted before, as well as revisit some old friends. The diversity of species found in this one area is impressive and made for varied painting.
I’m pretty pleased seeing them all together like this, and I hope you’ll enjoy them too!
Blog dedicted to phytoplankton. Phytoplankton are microscopic organisms that are responsible for half of the photosynthesis that occurs on Earth. Oh, and they look like art...
