We’ve traveled far, this last week. From gentle basking sharks gliding across the surface of the North Sea to titanically tiny worms dwelling in the deep. The variant cover for Aquaman #31 is a fantastically diverse sampling of real ocean organisms, many of them not only profoundly weird but also almost entirely unstudied. Mike Allred’s is a small taste of the unknown still waiting to be explored.

I saved the best for last, including my favorite squid and scale worm. Before we dive into these final identifications, let’s take a moment to review.

Nereus, never to rise.

Reports are coming in from the Kermadec Expedition that Nereus, the world’s first Hybrid AUV/ROV and deepest diving robot, has perished. The full-ocean capable robot, who dove to the bottom of Challenger Deep several year before James Cameron’s Deepsea Challenger, was lost on a 10,000 meter dive in the Kermadec Trench. Researchers and crew members were hopeful that the fail safes built into the robot would return it to the surface, but, when the small spheres that provided her buoyancy broke through the waves, it was clear that Nereus had been irrecoverably damaged, never to rise again.

Nereus joins ABE and Kaikō on the sea floor, permanently entombed in Davy Jones’ locker. There are now only two vehicles left in the world that can dive to the very bottom of the deepest ocean.

I sing the praise of my robot underlings, the workhorses of deep sea exploration.

The penultimate installment of the incredible biodiversity of Aquaman’s variant cover

aquapurged5We are approaching the home stretch, with the second to last installment of our tour through this amazing Aquaman cover. Have you been following along? How many have you guessed so far?

If you haven’t been following along, you can catch up with the previous installments, below:

seahorseI started my career in marine science working with seahorses, so these goofy, thoroughly un-fish-like fish, hold a special place in my heart. All seahorses are pretty weird, but pygmy seahorses might be the weirdest. These tiny animals, barely 2 centimeters long, live exclusively on gorgonian corals, their lump profile allows them to blend perfectly into the backdrop. Their bulbous protrusions will assume the color of their host coral.

The incredible biodiversity of Aquaman’s variant cover: Part four of a six part trilogy.

aquapurged4Welcome to day four of our delightful tour through the weird, wonderful creatures on Michael Allred’s incredible Aquaman cover. It’s all fish today!

Since we’re at the halfway point, now seems like a good time to reflect on why this cover matters so much. I’ve been a fan of Aquaman for a long time, and for all the amazing visuals in the latest iteration of our Atlantean hero, the deep sea remains noticeably underrepresented. Comic books mirror life and it is rare to see deep-sea creatures feature in art, let alone popular art. To have so many deep-sea organisms featured prominently on a piece of genre-crossing pop art is a rare and welcome opportunity to share my love for fangtooths, vampire squid, vent worms, monkfish, fringeheads, and isopods with a new and diverse audience.

Downward with the bestiary of barotollerant glory!

The incredible biodiversity of Aquaman’s variant cover: Episode 2

Welcome back to another exciting installment of the incredible biodiversity of this incredible Aquaman cover. Today we’re investigating species 4 through 6, where we’ll meet one of my favorite mid-water fish.

fangtooth4. Fangtooth (Anoplogaster cornuta)

With the largest tooth-length-to-body ratio of any fish, the fangtooth has earned its menacing name. Unfortunately, this intimidating creature barely reaches 18 centimeters in length, hardly the massive, Batman-swallowing maw illustrated to the right. Fangtooths are among the deepest swimming fish. They can be found as far as 5000 meters down, though they are more common in the midwater (200-2000 meters). Read More

The incredible biodiversity of Aquaman’s variant cover

Aquaman. Wow. Artist Mike Allred has seriously outdone himself with this incredible variant cover to Aquaman #31, featuring a 75th anniversary tribute to Batman as well as an incredible pastel array of deep-sea creatures. What truly amazing about this cover is that each one of these animals is a real living denizen of the deep right here, on Earth Prime. Sure, the scale might be a little off, and it’s unlikely that a scale worm could swallow a Bat-thyscaph, but the salient details are uncanny. Join me on a tour of the 18 wonderful animals featured on this sure-to-be epic installment of Aquaman’s ocean-spanning adventures. Today we’re looking at the first three, including one of my all time favorite marine organisms. Read More

Florida fisherman catches an 18 foot goblin shark, the second ever caught in the Gulf of Mexico

Last week, commercial fisherman Carl Moore was fishing for royal red shrimp off the coast of Key West Florida.  When he pulled up a net from more than 2,000 feet, Moore had caught something other than just shrimp. In his net was an unusual looking enormous fish—a goblin shark more than 18 feet long. As Moore reported to the NOAA scientist he reported his catch to, “it was uglier than a mother-in-law.”

This rare species of shark has only been seen in the Gulf of Mexico once before, in 2002. Though goblin sharks have been occasionally caught in the Atlantic and Indian ocean and a large group was caught in Taiwan following an undersea earthquake, most specimens have been found in the deep water canyons surrounding Japan. They are occasionally caught as bycatch in deep sea fisheries, as happened with Carl Moore. Unlike many species of shark, “they don’t have any commercial value, other than their jaws,” says Charlott Stenberg, a marine biologist and science writer. “But, I have a Japanese friend who ate some of it and thought the tongue was delicious”

Goblin sharks can be easily identified by their bizarre jaw, which protrudes a great deal while eating (video). The jaw of the goblin shark gives them their Japanese common name: Tenguzame, which references a mythical half human and half bird creature called Tengu. Their long, flat snout, relatively small head, and pink coloration are also distinctive. “ I love them because they’re pink, they’re mysterious, and they live deep among other cool creatures,” Stenberg says. I know many people think that they are ugly, but that just makes me love them more.”

“NOAA biologists encourage people to call and report these rare sightings and catches, as the information they can collect allows them to know more about a species,” according to the official statement about this goblin shark by the National Marine Fisheries Service, After taking the photographs shown above, Carl Moore quickly released the goblin shark, which swam away.  This story spread without all of the correct information, initially resulting in several colleagues and I believing that Moore still had the shark and that it was possible to get samples for research projects. I am glad that this rare shark was released alive and reported to the proper authorities, and I will be writing a follow-up post soon explaining what to do if you catch a rare fish that does not survive. Such a specimen could benefit numerous ongoing research projects and help scientists to better understand a little-known animal.

Documenting Deep Sea Drama: Pursuing the Reality of Ocean Acidification

1Kaitlin Kovacs is a researcher for U.S. Geological Survey – Southeast Ecological Science Center. While she currently works in a deep-sea benthic ecology lab, her previous science adventures have led her to study artificial reefs in Florida, coral reef restoration in the Maldives, and coastal ecosystems in the U.S. Virgin islands. With her marine science background, Kaitlin is keen on using outreach and education to help engage local communities in marine conservation efforts.

The ideas expressed below do not represent U.S. Geological Survey.

In the cult Wes Anderson film, The Life Aquatic, there is a scene in which a documentary film maker asks the protagonist, Steve Zissou (clearly a spoof of Jacques Cousteau) what the scientific purpose of his mission to kill the endangered Jaguar shark would be. The eccentric Zissou (brilliantly portrayed by Bill Murray) answers simply, “Revenge.”

The humor here is that scientific missions are rarely so openly coupled with emotion. And yet, the quirky marine biologist does not bother to hide that he is consumed with emotion after his partner is eaten by a shark. His anger and sadness fuel his scientific objective.

One-fifth of all known hydrothermal vents are threatened by deep-sea mining

Few moments have so profoundly altered our understanding of what it means to be a living thing on Planet Earth as the discovery of deep-sea hydrothermal vents and the organisms that thrive around them. The first vents visited were dominated by Riftia pachyptila, the giant tube worm, whose magnificent ruby plumage parted to reveal an entire community adapted to harness the chemical energy that poured from the vents. It is almost poetic that the first vents were found on the Galapagos Rift; the same tectonic feature contributed to another great, formative moment in biology — the Voyage of the Beagle. Hydrothermal vents provided the first evidence that the sun was not the only source of energy that living organisms could harness. They opened our eyes to the potential of chemosynthesis and hinted at an ocean of unfathomable wonders waiting to be discovered.
