In this book kids learn about sharks and the oceans as they travel with Norman on his adventure through the Bahamas.
Sharks4Kids First Book: Meet Norman the Nurse Shark
Sharks4Kids is an educational non-profit based in Florida that produces curricula and media designed to teach primary-school age kids about sharks and shark conservation. They also conduct Skype-in-lessons, classroom visits, field trips, and shark tagging camps. For their first Kickstarter campaign, they’re producing a book, targeted at elementary-school students.
Sharks matter, according to my co-author who uses the handle WhySharksMatter, and ocean outreach literature targeting younger students is often light on solid educational content. Online media is great, when available, but not everyone has reliable access to the internet. One of the campaign goals is to distribute this book to schools in the Bahamas, which is a major benefit to a region where persistent, high-bandwidth internet is not always a given.
Onward to the Ocean Kickstarter criteria!
1. Is it sound, reasonable, and informed by science? Sharks4Kids has a solid tract record producing entertaining and scientifically literate content that appeals to a younger audience. I have no doubt that Norman the Nurse Shark, though necessarily anthropomorphized, will provide fact-based, pseudoscience-free information about nurse sharks. Continue reading
Happy Fun Science FRIEDay! After a brief hiatus, due to life, hoping this installment represents the regular…err, semi-regular, occurrence of FSF.
So this hit the interwebs pretty big earlier this week, the first documented reptile to glow. That honor belongs to the Hawksbill a sea turtle, observed first by David Gruber, of City University of New York.

Lets get one thing out of the way before we delve into the glowing version of Crusher (for my finding Nemo aficionados). The sea turtle is not glowing, its fluorescing… there is a difference. In the ocean lots of organisms fluoresce at longer wavelengths (green, yellow, red) in response to shorter wavelengths (UV, blue, violet). It is a typical property of many biological materials and is noticeable if viewed through restrictive long pass filters, as is the case here.
That being said, documenting a sea turtle fluorescing is still pretty freaking cool! Like many scientific discoveries this was totally by happenstance. David was in the Solomon Islands to film biofluorescence in small sharks and coral reefs. And during his observations of sharks and corals glowing Crusher just swims by like, “Dude, I’m all glowing and stuff.”
Checkout the awesome video of it below, and Happy FSF!
This week, I and a team of marine ecologist, explorers, and ocean technologists published Robots as vectors for marine invasions: best practices for minimizing transmission of invasive species via observation-class ROVs. This paper, conceived and largely produced during the ROV2PNG Marine Science Short Course in Papua New Guinea, represent the current best practices for minimizing or eliminating the spread of invasive species via portable, low-cost underwater robots.

Species invasion, particularly in the ocean, is a huge problem. Invasive species are ruthlessly good at out-competing native fauna. Without any natural predators, they can flourish, causing massive, irreparable damage to marine ecosystems. As scientists, explorers, and conservationist, we have to be proactive in ensuring that our actions don’t negatively impact the ecosystems we’re trying to save. Our guidelines are simple, but effective, and, most importantly, easy to follow.
- Educate yourself about species invasions generally and specifically about current issues in the area you’re working.
- Inspect your gear.
- Soak your gear in freshwater between dives.
- Soak your gear in weak bleach between expeditions.
- Avoid moving your equipment between geographic regions, when possible.
Technology can be a powerful tool in the aid of conservation. Around the world, people are using low-cost robotics to count elephants, detect poachers, protect tortoises, even seek-and-destroy invasive sea stars. As I discuss over at Motherboard, these robots are a transformative component of 21st century marine science and conservation, they fundamentally reshape the way we interact with the ocean. And with the explosive success of the latest OpenROV launch, there are about to be a lot more robots in the water. This is a good thing. The more eyes we have in the sea, the more people that actively contribute to ocean exploration, the more people with access to the tools necessary to explore, study, and understand our oceans and how they are changing, the better off we will all be.
Several images circulate on the internet that capture the plight of rapid Arctic climate change, a phenomenon known as Arctic amplification. This image, for me, is the most alarming:
It’s been a big week for papers here at Southern Fried Science. This morning, Amy, myself, William (of Bomai Cruz fame), and Dominik and Erika of OpenROV published our guidelines on minimizing the potential for microROVs to act as invasive species vectors in Tropical Conservation Science. The abstract:
Remotely operated vehicles (ROVs) present a potential risk for the transmission of invasive species. This is particularly the case for small, low-cost microROVs that can be easily transported among ecosystems and, if not properly cleaned and treated, may introduce novel species into new regions. Here we present a set of 5 best-practice guidelines to reduce the risk of marine invasive species introduction for microROV operators. These guidelines include: educating ROV users about the causes and potential harm of species invasion; visually inspecting ROVs prior to and at the conclusion of each dive; rinsing ROVs in sterile freshwater following each dive; washing ROVs in a mild bleach (or other sanitizing agent) solution before moving between discrete geographic regions or ecosystems; and minimizing transport between ecosystems. We also provide a checklist that microROV users can incorporate into their pre- and post-dive maintenance
