It’s generally thought that baleen whales are too large to be successfully attacked by most marine predators. Orcas are typically considered the only real predatory threat to large whales, and even they have to use teamwork to take down a young whale. Large sharks, which also sit near the top of the marine food web, are known to scavenge on whale carcasses as a nutritious and blubbery supplement to their usual diet of fishes and smaller marine mammals. However, evidence has been found that white sharks actually take a proactive approach to increasing the whale carcass supply by attacking live northern right whale calves. Now researchers in South Africa directly observed dusky sharks actively teaming up to bring down a humpback whale calf.
OPAH, OPAH, OPAH!
Recently scientists at NOAA’s South West Fisheries Science Center made a stunning discovery, the worlds first known warm-blooded fish, the moonfish, opah (Lampris guttatus). Until this recent discovery all fish were considered cold-blooded ectotherms – allowing their body temperature to fluctuate with the change in ambient ocean temperature. However, opah’s are different, in that these largely solitary fish regulate their internal body temperature above the ambient temperature of their environment like mammals and birds (other warm-blooded animals).

I first heard about the new Wyoming law #SF0012 through the Slate article summarizing it as a criminalization of citizen science. There’s a real danger that it could be interpreted and implemented that way, but let’s try and give Wyoming the benefit of the doubt for a minute. The text of the law only requires that scientists (citizen or otherwise) acquire written or verbal permission from landowners for collecting data on their land. It goes on to define what “data” means, including photographs in a fairly wide definition, and “collecting” as taking data with the intention of turning it over to a state or federal agency. It also defines trespassing and outlines the consequences for those who fail to receive permission. In short: the data collector could go to jail and their data will not be admissible in legal or policy proceedings.
At the core, the law re-hashes a fairly common definition of trespassing. The key part of the law that’s new is that the data won’t be admissible in court and the act of turning them over to federal or state agencies will make you an outlaw. Part of me thinks that data collectors, including citizen science groups, should be asking permission to go on someone’s land. This is both to keep ethics at the forefront of our scientific endeavors and for the personal safety of scientists (ranchers are known to carry shotguns, after all).

Last month we crowdfunded an initiative to buy everyone’s favorite shark conservation superstar a new, less ugly pair of sunglasses. We blew our initial goal out of the water, raising nearly $2500 from almost 100 people. Amazing! Rewards are going out over the next few weeks (I’m mailing all the big teeth today. The smaller … Read More “A huge thank you to all who helped make “Buy David Shiffman less ugly sunglasses” a success” »
Today I was at an undergraduate research event with our best and brightest presenting their research via posters – great science, but often dreadful posters.
Posters can be a great medium for getting your science over to an audience. They have the benefit that if you can draw people into your poster you can have a lot more intimate face to face discussion with your peers. But first you have to draw them in…
Increasingly poster sessions in conference are becoming large sprawling events, and your poster is going to have to compete for attention with hundreds if not thousands of other posters, with your audience having little time to browse, they may be distracted by friends and colleagues, they may be tired as poster sessions are often at the end of a long day of presentations, and possibly (probably) slightly to moderately drunk. Here are some simple tips for making a good poster that has impact.
Raise your hand if you realized there were frogs so translucent you could see their innards? Ok if you actually raised your hand while reading this, kudos, but put it down now. Glass frogs are tiny green organisms whos organs are visible from their underside given the translucent nature of their bellies. There were 148 … Read More “Happy Fun Science FRIEDay – Glass Frogs” »
In 2013 a colleague and I were commissioned by Cambridge University Press to write a book about applying to graduate school in the sciences. A large part of the approach was to source knowledge from others with experience in this process (both from admissions offices and former applicants), and to use that information to drive … Read More “Advice About Applying to Graduate School” »
Two years ago, I moved to San Francisco. It was… an experience. I had the opportunity to meet some incredible technologists, leaders in the emerging world of citizen exploration, and developers, coders, and makers using their skills and expertise to help save the environment. I met some amazing drone builders developing platforms and tools to measure the world. I also learned that West Coast living was not for me. The southern Atlantic coast called me back. But before I left, I led a small team across the Pacific to Papua New Guinea, where we taught undergraduates from the University of Papua New Guinea and the University of the South Pacific how to build and operate OpenROVs and incorporate them into marine ecology research.
The West Coast was good to me. It helped refine my vision for bringing low-cost, open-source technologies into the marine science and conservation world. Citizen science is becoming increasingly important, and the need for both democratizing and decolonizing science will drive much of the evolution of the scientific community in the 21st century. Tools that are effective, cheap, and open-source will play a major role in this transition. I returned east and began planning the next phase of this vision.
The Chesapeake Bay (San Franciscans take heed, you can keep your “Area” but “The Bay” will always be the Chesapeake) is the largest estuary in the United States, is economically important for shipping, fisheries, and tourism, and also happens to be the body of water that I grew up on. I learned to swim, fish, sail, and motor in one of the Bay’s many tributaries. It’s also home to more than a dozen research institutes, which work, sometimes in coordination and sometimes not, on studying and protecting the Bay.

You’ve been there before. You are sitting or standing around and get a mental sensation that you need to “pop your knuckles”. A swift squeeze of your fingers and the tension is relieved. Crisis averted. But why do knuckles make that popping sound when you crack them? If questions like this keep you up at night… maybe you need to reevaluate your priorities. But, if the start of this article has piqued your interest, you will be pleased to know that a a team of researchers, led by the University of Alberta Faculty of Rehabilitation Medicine, have confirmed the reasons for knuckle popping.
