Amidst all the hysteria surrounding the seemingly unstoppable COVID-19, we bring you a story of a fish without blood. In 1928 a biologist sampling off the coast of Antarctica pulled up an unusual fish. It was extremely pale (translucent in some parts), had large eyes and a long toothed snout, and somewhat resembled a crocodile (it was later named the “white crocodile fish). Unbeknownst at the time, but the biologist had just stumbled on a fish containing no red blood pigments (hemoglobin) and no red blood cells – he iron-rich protein such cells use to bind and ferry oxygen through the circulatory system from heart to lungs to tissues and back again. The fish was one of sixteen species of what is now commonly referred to as icefishes that comprise the family Channichthyidae, endemic around the Antarctic continent.Read More
Scientists (and sci-fi fans) have to varying degrees been discussing the concept of suspended animation for years; the idea that the biological functions of the human body can somehow be put on “pause” for a prescribed period of time while preserving the physiological capabilities. If you’ve ever watched any sci-fi movie depicting interstellar travel you have probably seen some iteration of this concept as a way to get around the plot conundrum of the vastness of space and space travel times, relative to natural human aging and human life span. The basic principle of suspended animation already exists within the natural world, associated with the lethargic state of animals or plants that appear, over a period, to be dead but can then “wake-up” or prevail without suffering any apparent harm. This concept is often termed in different contexts: hibernation, dormancy, or anabiosis (this last terms refers to some aquatic invertebrates and plants in scarcity conditions). It is these real-world examples that likely inspire the human imagination of the possibilities for suspended human animation. The concept of suspended human animation is more commonly viewed through the lens of science fiction (and interstellar travel), however, the shift of this concept from scientific fiction to science reality has a more practical human application.Read More
A couple of years ago, several of the people organizing the International Marine Conservation Congress let slip in their planning discussions that they played Dungeons and Dragons (D&D). There are many of us of a certain age that remember fondly playing in our youth, some of us have kids who are now getting of an age where we can, in turn, teach them how to play, and some were drawn in by the surge in Youtube and podcast shows like the hugely popular “Critical Role” where literally millions of people turn in to watch a bunch of nerds play Dungeons and Dragons … and have fun.
This led to the idea of playing a game at the conference. After more discussion, perhaps helped by a few drinks, the idea was spawned that perhaps we could make this game marine-themed and educational? Maybe even play this game in front of an audience at the conference? Perhaps even record it and share it online…?!Read More
The Emperor of all Maladies is how Siddhartha Mukherjee, an Indian-born American physician and oncologist, aptly described cancer. Cancer, this scourge of mankind going back as far as 4,600 years ago when it was identified by the Egyptian physician Imhotep (the first in recorded history). Cancer takes one of the most successful traits of complex eukaryotes, cell division, and weaponizes it in unchecked cellular growth; some even consider cancer to be a more evolved form of cell division. This ailment has plagued humanity, and baffled physicians for centuries as they attempt to tackle the seemingly impossible, discover a cure for cancer.Read More
Just when you thought it was safe to read another decade-in-review listicle…
As the 2010’s come to an end, it’s a time to reflect on the often-problematic decade that was as we plan for a hopeful future. I am a sucker for year-in-review and decade-in-review listicles, and was devastated to learn that no one had yet written a decade-in-review listicle for sharks! Please enjoy my official, scientific list of the most important science, conservation, and pop culture sharks from the past decade.Read More
Inception, a clever movie starring Leonardo DiCaprio where the premise of the story is to sneak into a person’s subconscious and implant an idea or a memory whilst they sleep. When the person awakes from their slumber they cannot distinguish the implanted memory from their own. It makes for blockbuster cinematography, but the practical concept is quite frightening to think about: the ability to artificially implant memories inches closer to the prospect of reality distortion.Read More
My 35th birthday is next week, and I am calling upon the forces of the Internetz to help make it an amusing one. As you all know, sandbar shark is #BestShark. This spectacular shark is even the logo of my new consultancy!
I want you to help me celebrate my birthday by creating sandbar shark #BestShark memes and/or artwork! And my favorites will win prizes! Here’s how it works:Read morE

Can you remember how young you were when you were first taught stop, drop, and roll? How about turn around, don’t drown? Slogans are abridged stories that fulfill our human need to convey information quickly and memorably. Their uses range from social connection, cooperation, and informing cohorts of risk. Sayings like the above are effective because of these three main achievements:
- They are memorable.
- They incorporate knowledge with action.
- And by fearlessly acknowledging rare, potentially fatal, risks – they create a constructive dialogue.
Imagine a world without stop, drop and roll where children are simply taught that there is an incredibly rare risk that they could catch fire, and that’s it. While the statistic may be true, just providing the information would result in a classroom full of hysterical first-graders. A great slogan captured and presents the risk fearlessly.
Put another way, slogans are science communication wins. So let’s get together and apply this human craft of slogan creation to another incredibly rare risk: shark encounters! Your risk of encountering a shark is extremely low–a statistic that is repeated ad nauseam. But just like our classroom of traumatized first-graders, stats alone aren’t always enough. Enter the #SharkSafetySlogan challenge!
Join us on twitter at #SharkSafetySlogan to crowd-source a memorable slogan. Shark experts and organizations from across the globe will be sharing sharky information to help you on your scicomm quest. Anyone who visits a beach is encouraged to participate!
Remember, keep it memorable, brief, and incorporate shark smarts with actions. An example could be:
Seals? Seabirds?! See ya!
The above slogan is brief, memorable, and incorporates the knowledge that an abundance of seals and seabirds is a strong indication that sharks are present, and you’re better off not swimming juuuust yet.
Come join us at #SharkSafetySlogan and see if your slogan ends up with the most likes and retweets! I’ll be leading the charge at @ScienceRhapsody. See you on the interwebs!

I can’t imagine a more useful introductory reference guide for new or prospective graduate students starting their career in marine biology than “Shark Research: Emerging Technologies and Applications for the Field And Laboratory”. This book is designed for people who have little to no familiarity with a research discipline but are about to start working in that discipline, a large and important audience that is often ignored by books and review papers geared towards people who are already experts. So many graduate students are told to learn a new research method by reading technical literature that assumes they already know this stuff, resulting in stress and frustration.Read More
