I’m constantly amazed by the beauty and diversity of life under Antartica’s ice. Below is one of the best videos I’ve seen of this stunning natural wonder. The water is below freezing, at a heart-stopping -1.5°C (29.3°F)*, a meter of ice covers the surface for much of the year, and the whole ecosystem is plunged into Antartica’s winter darkness for months at a time. Yet, look at this beauty. Look at all the creatures calling this alien world home. Watching this, I can’t help but wonder about all the mysterious places that we haven’t been. From the deepest depths under polar ice, to the watery moons of other planets. If this is what we’re finding so far, what else might be out there?

Transcript of video:
We’re diving under the sea ice in O’Brien Bay, south of Casey research station in eastern Antarctica.
This is a thriving, colorful world filled with sponges, sea cucumbers, sea spiders, worms, algae and starfish. Here we are at 30 m below the surface, where the water temperature is a chilly −1.5[°C] year round, and the sea is covered by ice that is a meter and a half thick for more than 10 months of the year.
This ice provides protection from Antarctica’s harsh weather conditions, and a stable marine environment that allows biodiversity to flourish. This important biodiversity is the focus of our research into the effects of climate change and ocean acidification.
Here at the Australian Antarctic Division, we’re working hard to ensure the continent remains valued, protected and understood.

*The salt in seawater lowers the freezing temperature, and prevents the water from turning to ice at 0°C (32°F), much the same way road salt melts the ice on roadways.

The Process.
Last year, DSN compatriot and Captain of the rag-tag crew over at Southern Fried Science, dropped a science outreach bomb. Dr. A.D. Thaler struck some ecological/technological brilliance in the form of the Scanning the Sea project. In a word, I was inspired and wanted to do my part in pushing this magical ocean outreach toolbox forward and to the masses. Over the past year, and with Andrew’s much appreciated mentorship, my team and I have been working diligently to compile the next piece in the 3D puzzle.
I am stoked to unveil the Rocky Intertidal segment to the #ScanningtheSea library in the form of “3D Cabrillo.” Working at a National Park revealed the perfect opportunity to preserve the resources in this way and make them available for the public.
3D Cabrillo is a multifaceted educational resource and experience available to educators both near and far. In local collaboration with the Scripps Institute of Oceanography and the La Jolla Library, we utilized the #ScanningtheSea methodology to create biomodels of many of the prominent organisms found in our Rocky Intertidal Zone. Free downloadable versions of these models are available to the public on the park’s website at the 3D Cabrillo Biomodel Library. These models can be produced on any 3D printer. Our hope is that this will increase accessibility of ocean resources throughout our community and beyond.
In conjunction with the biomodel library, we developed an interactive Student Resource Manual. This takes students through a step-by-step guide on how to create and render 3D models. The 3D Cabrillo Student Resource Manual was specifically developed to connect students to the ocean ecosystems, while simultaneously teaching 3D printing techniques. We look forward to implementing this program with local schools during their upcoming Spring semester and putting their work on display for thousands of visitors to see and learn from.
Using the new tools available to us, we seek to reach the public in different and exciting ways. Our goal is that this initiative will highlight the public’s important role in awareness and stewardship of our ocean resources. By connecting nature and technology, we look to foster excitement in the next generation of environmental stewards.
A special thanks to Andrew D. Thaler for inspiring this project and his ongoing commitment to ocean science education. Onward Captain.

*alternative titles include “Looking a gift seahorse (genome) in the mouth”, “My kingdom for a seahorse genome”, “Hold your seahorses“, and “The galloping evolution of seahorses“.
Let’s face it, seahorses, pipefishes, and seadragons are messed up. That’s not a subjective opinion but an evolutionary fact. It’s like all the approximately 300 species in Syngnathidae (the family of fish that contains all these critters) held a meeting and decided unanimously “Nah, screw it, we’ll do things however we damn well please.” The Syngnathids are revolutionaries of the fish world. ¡Viva la Evolución Revolución!
Seriously, almost everything in these species is different. There is the elongated snouts and small mouths and jaws. The pelvic and caudal fins are often gone. The scales are replaced with an armor of bony plates. Let’s not forget about the whole “male pregnancy” thing where the males nourish the developing embryos in a pouch. Seahorses take it all to a whole other level with the prehensile tail and the vertical body axis.
So ultimately, one is left wondering what’s up with those genes? Well, thanks to an intrepid group of geneticist, the complete genome of the tiger tail seahorse, Hippocampus comes, is complete. With the full genome comes great power, the ability to compare this genome to the other sequenced fish.
Part of the story regarding the bizarreness of seahorses is gene loss. Secretory calcium-binding phosphoprotein (SCPP) genes code for matrix proteins that are important in the formation of bone and teeth. These genes are completely missing in Hippocampus comes and may explain why seahorses do not have teeth. Did I forget to mention that? Yeah seahorses and seadragons are toothless. The tbx4 gene, conserved in jawed vertebrates, acts as a regulator of hindlimb formation. The gene is completely absent in the seahorse genome and explains the absence of those pesky pelvic fins.
What about that whole “male pregnancy” thing? The H. comes genome contains six pastn genes, part of a family of genes that regulate the hatching of embryos. The researchers conducted extra work, like the genome was not enough, suggesting a role for these pastn genes in brood pouch development and/or hatching of embryos within the brood pouch prior to birth.
Seahorses have also apparently lost many conserved noncoding genes (CNEs) that function as enhancers, repressors, and insulators of other genes. 1,612 CNEs have been lost in seahorses. Compare this to the 281 in the Nile perch. It is unclear how the loss of the CNEs may be related to some of the oddities of the seahorse, but loss of CNEs is tied to moderate short stature and shortened limbs in humans.
How I imagine the scientists of the study acted once they finished the genome
The awesomeness of this kind of work cannot even be articulated. The researchers have done an amazing job of unpacking the genome of a seahorse and showing how genome evolution directly leads to all the uniqueness of seahorses. Admittedly, I am little disappointed in not seeing a discussion of the prehensile tails genes and armored plating discussed. I guess I’ll need to wait a bit to build my army of aquatic minions to take over the world.
