Over 15 years of ocean science and conservation online
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 … Read More “Florida fisherman catches an 18 foot goblin shark, the second ever caught in the Gulf of Mexico” »
Kaitlin 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.

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.

Carcharocles megalodon, commonly known as the megalodon, was likely the largest shark that ever lived. I say “was”, because despite claims by certain Discovery Channel “documentaries”, there is absolutely no doubt whatsoever that the megalodon is extinct and has been for millions of years.
It isn’t surprising, though, that the largest shark that ever lived has such an impact on pop culture. Recently, we watched the latest in the spectacular “mega shark vs.” science fiction series, one of my favorite movie series based on extinct giant sharks coming back to life and wreaking havoc on the modern world. The Southern Fried Scientist, who recently calculated how much Old Bay seasoning you’d need to properly cook the latest Aquaman villain, asked me how much shark fin soup you could get from an adult megalodon.
Based on my calculations, the answer is about 70,000 bowls of shark fin soup, more than enough for everyone who lives in Greenland to have a bowl. Explaining where this number comes from can tell us a lot abTTout one of the most important ocean conservation issues facing the world today.

On January 1st, 2012, new Florida Fish and Wildlife Conservation Commission regulations came into effect, making it illegal for fishermen to land great, smooth, or scalloped hammerhead sharks in Florida waters. The legal term “land” is clearly defined in the Florida Code:
“Land,” when used in connection with the harvest of marine organisms, means the physical act of bringing the harvested organism ashore”
“Harvest” means the catching or taking of a marine organism by any means whatsoever, followed by a reduction of such organism to possession. Marine organisms that are caught but immediately returned to the water free, alive, and unharmed are not harvested”
Florida code section 68B-44 (emphasis mine)
In other words, if a fish is brought out of the water, it is “landed”. If anglers stop the act of releasing a fish to measure it or take a photo, it is not “immediately released.” If a fish isn’t “immediately returned alive and unharmed” (and if the extremely physiologically stressful act of bringing a hammerhead out of the water results in it dying after release, it was not released “unharmed,”) it is harvested. If you drag the shark out of the water and leave it there until it stops moving long enough that you feel safe to approach it, that is not an “immediately released” animal, and it isn’t an animal that is “released unharmed.” Landing and/or harvesting hammerhead sharks is illegal. This is clear under the law, and has been confirmed by numerous consultations with an FWC Law Enforcement official.
Mega Shark vs. Mecha Shark, the third installment of the amazing “Mega Shark vs.” series, is now on Netflix streaming! In 2009’s Mega Shark vs. Giant Octopus, a megaladon and a giant octopus were accidentally released by climate change, which led to a path of destruction around the world… until a scientific team involving Debbie Gibson … Read More “Watch Mega Shark vs. Mecha Shark on Netflix Wednesday at 10 p.m., and tweet along with us!” »
I didn’t expect a throw-away post I made last Friday debunking an alleged image of the Loch Ness Monster to go viral, but this is the internet and these things happen. As you might expect, my inbox, social media accounts, and this website have been inundated with comments about that post, how wrong I must be, what’s really going on, and why X theory is clearly the correct one. For the record, it’s still a boat wake, but in light of the amount of attention the post received, I updated it with a bit more information about how that image could occur.
With that out of the way, here are my five favorite responses to the latest Loch Ness Monster sighting:

A recent piece in Science (Minteer et al. 2014) titled “Avoiding (Re)extinction” advocated avoiding collecting specimens for the sake of confirming the existence of a species. In lieu of killing and collecting the animal the authors suggest using “high-resolution photography, audio recording, and nonlethal sampling.” As a natural history curator of fishes I found this to be a pretty bad idea.
I don’t like killing animals, I was a strict vegetarian for 10 years (now I just eat sustainable seafood – hey, I live in Louisiana). I certainly wouldn’t want to endanger a species by over collecting it. I know of no scientific collectors who kill rare animals just so he or she can say they have it in their collections. We collect for a few simple reasons: because specimens are not available otherwise via loan, or additional specimens are needed for a comparative study, or because we need vouchers as evidence of the existence of the taxon.
I’ve collected rare species in the past, particularly some of the cavefishes I work on. For one of these species, Typhleotris mararybe, we collected the only two specimens we or anyone ever saw. We were in a very remote part of Madagascar and we were only allowed to collect two specimens from any given locality. I knew these individuals were part of a species new to science as soon as I looked at them. Did removing two samples place this species at risk of extinction? Guessing the population was much larger than what we found just at the surface, I would suppose not. What were we to do? Not collect them and just take pictures? We wouldn’t have been able to do the necessary comparative descriptive analysis to actually prove their novelty required by the ICZN (International Commission of Zoological Nomenclature). We collected these specimens so that we could formally describe this new and fantastic new species so that the world can be aware of their existence and so that measures can be put in place to conserve them and study them further.
Happy Fun Science Friday.
You did not mistakenly read the title, today we bring you the discovery of the first female penis in the animal kingdom.

Yoshizawa, from Hokkaido University in Japan, and his team of researchers documented this phenomenon of sexual role reversal in 4 species of rather unassuming insects in Brazil’s Peruaçu River Valley. When insects of the genus Neotrogla mate, the female mounts the male and penetrates his vagina-like opening with her penis.
It’s been a long time since we’ve had a good debunking-random-monster-sighting post. The ready availability of global satellite image databases is a powerful tool for exploration and monitoring but has also led to a boom in pseudoscience “discoveries” by people not familiar with how these images are produced or just willing to suspend disbelief for their pet woo.
This morning my inbox exploded with articles about the definitive Loch Ness monster sighting. The accompanying image is a low-resolution satellite image of a boat wake, available, apparently, only on Apple Maps. There’s really no deconstruction needed, it’s a boat wake. Compare this image from Loch Ness:

Last fall, I received an e-mail from a representative of one of my favorite companies: the Asylum, the film studio that brought you such cinematic masterpieces as “MegaShark vs. Giant Octopus,” “MegaShark vs. Crocosaurus,” and, of course, “SharkNado.” Following the spectacular success of SharkNado, they were interested in supporting shark science and conservation. After months … Read More “Help the producers of SharkNado 2 support our shark conservation research!” »
