Six things I learned about Giant Isopods while Sizing Ocean Giants

Today, Craig McClain, along with a massive team of ocean scientists (including me!) published our monumental paper: Sizing ocean giants: patterns of intraspecific size variation in marine megafauna. This massive monograph investigates patterns of size among 25 ocean giants, the biggest, most massive members of their respective taxa. You can probably guess which species I had a hand in reviewing.

Along the way, I learned quite a few cool things about the magnificent giants of the deep sea.

An open letter to new Discovery Channel President Rich Ross from a shark scientist

Dear Rich Ross, new President of the Discovery Channel,

I was excited to learn about your commitment to no longer show fake documentaries on the Discovery Channel. These shows have been incredibly damaging not only to Discovery’s goals of being the “number one non-fiction media company in the world” by”telling compelling and accurate stories,” but to public understanding of science and conservation. In recent years, the Discovery Channel has tried hard to actively muddle the fact that these documentaries were fake, including hiding vague disclaimers at the very end. I’ve spoken to hundreds of schoolchildren about sharks, and every time someone asks me about megalodon or mermaids. Viewers believed that they were real, and your channel actively bragged about the fact that people believed that they were real.

By claiming that megalodon isn’t extinct and mermaids are real but the government is covering this up, these shows resulted in scientists receiving threats and harassment, and resulted in important government agencies getting so many angry phone calls that they had to issue public statements. Producers for some of these shows intentionally lied to scientists to convince them to appear onscreen, intentionally lied to journalists about the facts behind them, and intentionally caused a real-life public panic. They actually showed a documentary about a legendary (read as “fake”) shark called Hitler. In short, I will be glad to see Shark Week and the Discovery Channel return to your roots of fact-based programming.

However, while “we won’t actively lie to viewers anymore” is an important step that I applaud, Shark Week and other Discovery Communications programs have many other problems that should be addressed. Shark Week 2014’s “Zombie Sharks” glorified wildlife harassment for no reason, as the entire stated goal of the show was for a non-scientist with a history of wildlife harassment to try to answer a question that scientists have known the answer to for decades. This problem is not limited to Zombie Sharks, but pervades Discovery Communications shows.

Snowy Owls and Goliath Groupers: Why I co-authored “Trophy fishing for species threatened with extinction.”

In both my professional and private life, I am a man who wears many hats. I am a deep-sea ecologist, a science writer, a goatherd, a geneticist, a conservation advocate, a grill master, and many others. When David asked me to join him in co-authoring “Trophy fishing for species threatened with extinction: A way forward building on a history of conservation” I did so not in my capacity as a marine science Ph.D., but as a recreational fisherman who cares deeply about the survival of his sport. Without fish, there is no fishing.

I was, at first, skeptical, but over the course of a summer, I came to appreciate what David was trying to accomplish.

I wrote most of my thesis on this boat, with a rod in the water.

Before I talk about fish, I need to talk about birds.

The era of the million-dollar tuna is over.

For the last several years, we’ve been following the first-of-the-year Tsukiji Tuna Auction. In the past, this auction has served as a (often questionable) benchmark for the demand for Bluefin Tuna. At its peak, the price of Bluefin Tuna broke the scales at nearly $1,800,000. As the price continued to inflate, last year we even released an early warning to journalists covering the auction, cautioning them against drawing too many conclusions about the expectedly massive auction price. We we’re all caught off guard when the price of the first fish barely topped $70,000 dollars, kilo-for-kilo not even the most expensive fish sold that day.

Today, the numbers are in, and the first Bluefin of the year sold for a measly $37,500, barely enough to cover the cost to fuel for a fishing boat.

Middle Earth could have been saved by the Endangered Species Act

In a cave in the Lonely Mountain there lived a dragon. Not a gnarly, goblin-stuffed, slimy cave, filled with the bowels of orcs and fishy creepers, nor yet an empty, granite, echo-less cave with nothing in it to lie down on or horde: it was a dragon-cave, and that meant gold. At least it did, until a nasty band of poachers found Lonesome Smaug, the last of his species, alone, asleep, threatening none, and smote his genus from the red ledger, stripping Middle Earth of critical biodiversity.

The ecologists of Carsondell would say, of the age of war that followed, that the men and dwarves and elves and hobbits brought the darkness upon themselves. Indeed, as the Dark Lord raised his army, denuded the forests, and belched carbon from the factories of Mordor, Gandalf the Grey, one of the more powerful, though among the least conservation-minded, of the wizards would remark: “It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough.”

The Grey Wizard failed to mention that, were it not for his callousness, there would be*.

What can Cloudy with a Chance of Meatballs teach us about ecology, sustainability and conservation?

My family loves to watch movies, which presents a problem during the few times we’re all together: there are very few good movies that none of us have already seen. This past Thanksgiving, we resolved that dilemma by watching some “based on a true story” garbage starring Nicholas Cage and the star of High School Musical, a plot-less but action packed shoot ’em up starring the governator and Sawyer from Lost, and “Cloudy with a Chance of Meatballs.”

Based on a popular children’s book, Cloudy with a Chance of Meatballs tells the story of Flint Lockwood, a young inventor who keeps trying to make life better for people in his small island town of Swallow Falls. His inventions always backfire, including the titular invention that makes the sky rain food. In the sequel, which I watched this past weekend because shut up I enjoyed the first one leave me alone, we learn that some of the food has become sentient. Swallow Falls is now home to a unique ecosystem that includes watermel-ephants, taco-diles, fla-mangos, and many other hybrids called foodimals. In addition to featuring some of the best puns I’ve ever seen, these movies also raise some interesting questions about ecology, sustainability and conservation.

There is 10,000 times more plastic in the deep sea than in surface waters.

Locations of sampling sites of bottom sediment and deep-water coral where content of microplastics was investigated. From Woodall et al. 2014.

Ocean plastics is one of the most pernicious problems facing the ocean. One-time use plastics, which, ironically, can persist for thousands of years, often find themselves carried downstream, settling on our beaches, our coastlines, and in large aggregations within oceanic gyres. We’re still trying to cope with the extent to which plastics, and particularly microplastics–tiny photodegraded plastic particles, impact marine ecosystems. Earlier this year, ocean plastics made major waves when it was reported that not only do we not know how much damage they really cause, but we don’t even know where most of them go: 99% of the plastic that should be in the ocean is missing.

It looks like we found the missing plastic.

No Endangered Listing for Dusky Sharks (and That’s a Good Thing)

December 16, 2014 Chuck Bangley

Though the fisheries news cycle has mostly been taken up by the 15-year anniversary of the Sea Around Us project (and some choice words between researchers), today also marked the official announcement of the 12-month finding on the petition to list dusky sharks on the U.S. Endangered Species Act. Long story short, the National Marine Fisheries Service has decided that the dusky shark population in the Northwest Atlantic doesn’t need ESA protection to avoid extinction. While it may be tempting to decry NMFS’ decision as falling short for a species that has long been a prime example of declining shark populations, what it actually means is that things are looking up for the dusky shark. Finding that out only takes a little reading into the decision documents.
