These are a few of my favorite species: The magnificent and very large sponge Monorhaphis chuni

Within the glass sponges (Hexactinellids), so called because of scaffolds of silica spicules they form, resides a family of sponges, the Monorhaphididae. Family here is used in taxonomic sense to delineate substantially different types of organisms. Think the differences between cows and giraffes, both artiodactyls but in different families. But in the common meaning of […]

The complex wrath of the Ozone hole over Antarctica

Through its influence on atmospheric circulation, [the ozone hole] has helped to shield the Antarctic continent from much of the effect of global warming over the past half century. (Robinson & Erickson, 2014) That’s not a sentence I expected to read in a scientific paper. Most of us probably don’t think about the ozone hole that much […]

All Female Bone-Devouring Worms Fancy Dwarf Males, Except One

Our guest post is by Dr. Marah Hardt, a marine scientist and storyteller working to build a sustainable future for people and the sea. She is the Research Co-Director at Future of Fish and currently working on her first book, Sex in the Sea (www.sexinthesea.org). You can follow here on Twitter @Marahh2o. Fifteen years ago we didn’t know they existed. In 2002 […]

Epic Science Raps of History – A teaser

It all started on a perfect San Diego summer night, Taco Tuesday to be exact (For those of you who don’t live in the local area, all things good in the world happen at Taco Tuesday). My friend and colleague from Scripps Institute of Oceanography, Levi Lewis, had called a meeting of the science rap braintrust, […]

These are a few of my favorite species: Desmarestia

This is acid. This is your seaweed on acid. Sulphuric acid to be exact. A highly corrosive substance, also known as oil of vitriol, H2SO4 is one of those ‘strong acids’ essentially meaning that yes, I actually wear gloves/goggles/lab coat/body armor (if available) when I am using it for legitimate fear of it getting on […]

These are a few of my favorite species: Hermit crabs without shells

Hermit crabs are generally awesome. They use snail shells, and sometime shells of other mollsucs, to protect their non-skeletonized squishy backends. Some are even adapted to live in burrows coral, wood, and old worm tubes, again to keep those soft rear ends protected. But one group of hermit crabs does something colossally different and it […]

The Disappointing Reality of Musical Fish

Fanciful common names of fishes suggest there may be an orchestra in the sea, but this is yet another way the underwater world lets us down. In the heat of the cold war when cloak-and-dagger espiponage went below the sea, the US Navy was listening to fishes. Ideally, after identifying all the strange sounds generated […]

The Patron Saint of Marine Scientists

Saint Brendan of Clonfert is often referred to Brendan the Voyager. He is Irish monastic saint born in 484 in Ciarraighe Luachra, near the present city of Tralee, County Kerry and died in 577. Besides founding several monasteries across Ireland, Brendan made a legendary journey. The tale of begins with Brendan and 60 (other stories […]

What single piece of advice would you give another scientist?

Recently I attended a talk by my good friend and fantastic researcher, Brian Sidlauskas. His talk was a retrospective over his research and what contributed to his academic success. A key part of his advice Don’t skip happy hours.   Weekly lunches, tea times, happy hours, and other structured but informal meeting times with other scientists […]

Is Jurassic World Violating CITES Protections?

Have you seen the new Jurassic World trailer?  As if I even have to ask…  Of course you have.  And of course you are amazed by the scene featuring what appears to be either a short-necked species of pliosaur (maybe a Kronosaurus?) or a super-sized version of a mosasaur, (an extinct marine reptile, not a […]

Six surprising reasons to be thankful for the sea

The oceans provides us with most of the oxygen we breath, much of the food we eat, and even all the water we drink, which has passed countless times through the seas. There’s no shortage of reasons to be grateful for our blue planet, but I thought I’d take a quick moment to appreciate some of the […]

These are a few of my favourite species: sarcastic fringehead

Most submissions to the “These are a few of my favourite species” series are interesting, to be sure.  Cute, even.  You got your fuzzy faced seals and your pretty nudibranchs and such.  They’re…nice.  But the rest of the DSNers can take a hike cos mine’s a bona fide winner.  While your nudibranch is gradually oozing […]

How the sons of undocumented Mexican immigrants built a ROV and won a national competition

I cannot wait to see Underwater Dreams narrated by Michael Peña, and written and directed by Mary Mazzio.  The story is how sons of undocumented Mexican immigrants built a ROV to compete in a national competition. Despite being poor kids with no resources, and starting off with no knowledge of how to build an ROV, they won beating […]

Putting snails in the microwave…for science!

Yahoo answers tells me I shouldn’t put snails in the microwave, but this paper tells me otherwise: Galindo LA, Puillandre N, Strong EE, Bouchet P (2014) Using microwaves to prepare gastropods for DNA barcoding. Molecular Ecology Resources, 14(4): 700-705. This paper is so simple, yet so epic in so many ways: We have experimented with […]

These Are Few of My Favorite Species: Humphead Parrotfish

As the as the largest species of parrotfish, a single individual of Bolbometopon muricatum can ingest over 5 tons of reef per year. That freaky looking bump is also for head butting rival males.  What’s not love. And now with the help of the Digital Underground. All right! Stop whatcha doin’ ’cause I’m about to […]

The Antarctic is a rough neighbourhood

There’s a fascinating article getting some press this week, all about a growing incidence of an extraordinary bit of animal behaviour in the islands just above the Antarctic circle.  In an article in the journal Polar Biology, reported on nicely by the BBC (with more disturbing pictures and video), scientists from the Mammal Research Institute in […]

Lies, Damned Lies, and Cryptozoology

Don’t believe everything you read on the internet, despite what cryptozoologists may be telling you. The internet is a double-edged sword of enlightenment and ignorance. It has the capacity to educate millions in ways never before possible, making science accessible, understandable, and relevant. At the same time it infects the public with idiocy, lies, pseudoscience, […]

Shark Feeding, Managed Risk, and the Tredwellian Paradigm

Ocean conservation work takes me to many an unusual locale, but none stranger than tomorrow’s destination: Las Vegas.  I’m headed there to attend the annual Diving Equipment & Marketing Association, or DEMA Show for short.  The DEMA Show is the world’s largest international trade show for the scuba diving and water sports industry.  The exhibition […]

TGIF – Zoiks! Lionfish!

This extraordinary bit of footage shows quite the highest density of invasive lionfish I’ve ever seen.  I was talking to Luiz Rocha during the week and he tells me the footage was shot near Pensacola FL.  We agreed that neither of us had ever seen abundances like this in the natural range of lionfish.  We’re […]

These Are A Few Of My Favorite Species: Gasflame Nudibranch

About 350 million years ago during the Carboniferous, a group of snails took a new evolutionary route, one that eventually resulted in a complete loss of the most defining characteristic of a snail—the shell. These shelless snails eventually acquire another set of traits and now the most colorful displays on the planet occur in this […]
