How much weight is the “Ocean Atlas” really carrying on its shoulders?

Artist Jason deCaires Taylor has teamed up with B.R.E.E.F. to create “Ocean Atlas”, the worlds largest underwater sculpture. Underwater reef, diverter of tourists from natural reefs and a new hub for underwater selfies, “Ocean Atlas” is a sculpture of a woman supposedly holding the weight of the ocean on her shoulders.

These are a few of my favorite species: almost zombie like brachiopods

The lowly brachiopod.  They make my list because they represent the antithesis of a charismatic organism. Today the attention they get is mostly by mistake. Brachiopods are often confused for mollusks because of their superficial resemblance to clams. But if it wasn’t for that pesky Permian mass extinction, they might be kicking clam butt all over the place. 99% […]

Interview with the Vampire Blennies

This is our second guest post from ichthyologist, tech diver and all-round good guy Dr. Luiz Rocha at the California Academy of Sciences.  You should follow him on Twitter When you hear “vampires” you usually think “Twilight”, “Vampire Diaries” or “True Blood”. However, a very interesting group of fishes have also taken up the name. […]

These are a few of my favorite species: Anything with an instrument on it

As a physical oceanographer I have a love-hate relationship with sea life. Ocean biology is totally cool….until it interferes with my measurements. I’m looking at you barnacles on my ADCP. But swimming animals that can measure where oceanographers fear to tread, I am ALL OVER THAT. So here’s my favorite species…the ones I can stick instruments/tracking devices […]

These Are a Few of My Favorite Species: Carnivorous Sponges

Most sponges, inspiration for dish cleaners and mess absorbers, feed by filtering water through those many holes and channels.  Their scientific name, Porifera, literally means pore bearer.  The channels are lined with special cells,...Show More Summary

These Are a Few of My Favorite Species: Spotted Porcupine Fish

As scientific mariners, we spend an inordinate amount of shore time on sleezy docks and seedy piers around the world, from the gritty shipyards of Callao, to the bustling ports of Capetown, and the rowdy embarcaderos of Barbados. These landings provide a chance to shake off the sea legs on tierra firma, and sample the […]

Shark vs. CTD. Shark 1, CTD 0.

There is a common saying amongst oceanographers, “if you put something in the water, there is no guarantee you will get it back.” I’ve been in that situation before and it sucks. Unlike these guys, I’ve never had to actively fight the ocean to get an instrument back. What appears to be just ordinary shark fishing is actually an […]

These are a Few of My Favorite Species: Pistol Shrimp

My dream day includes Clint Eastwood and I drinking bourbon, smoking cigars, and watching The Outlaw Josey Wales. At one of the most memorable moments in the film, Clint as Josey Wales states “Are you gonna pull those pistols or whistle Dixie?” Shortly after projectile shenanigans ensue. Like Josey, Pistol Shrimp (Family Alpheidae), are entering guns […]

These are a few of my favorite species: Pig Butt Worm

This species bring a whole new meaning to butt face. It’s Latin name even means butt face.  I jest… it actually means resembling a pig’s rump. Chaetopterus pugaporcinus is a polychaete and like other worms it has segments.  Some of the segments are just a little bit inflated, i.e. this worm is all about the […]

These are a few of my favorite species: Painted Frogfish

Leaving alone on the seafloor is the lonely painted frogfish, Antennarius pictus. Males and females only come together for the dirty deed but quickly become intolerant of each other.  If the female stays too close, the male will eat the female…which in the whole evolutionary passing the genes to the next generation scenario seems like an idiotic move. […]

The strange world of the bright blue Velella

Over the past few months, odd floating jellies have been washing up on Pacific US beaches by the thousands. With clear plastic-like sails, and bright blue flesh, these harmless jellies have stumped many a beachcomber. Now, Steve Haddock...Show More Summary

Male, female, or both? When it comes to sex, fishes do it all!

This is a guest blog from Luiz Rocha, curator of Ichthyology at the California Academy of Sciences.  Luiz gets to do some amazing work documenting fish biodiversity around the world.  The Academy’s Philippine biodiversity expeditions have become an extraordinary collaborative enterprise that marries the best of biodiversity research and technical diving in the heart of […]

Whales Can Only Taste Salty

Five basic types of taste exist: sweet, sour, salty, bitter, and umami. Most people are familiar with all of these except the last, umami, which is best described as a pleasant savory taste. These tastes occur because of receptors that occur on cells in the mouth. Genes dictate the presence and number of these cells […]

The mysterious case of the missing manta bits

This spectacular picture has been doing the rounds of my Facebook network lately, of a Mr Bell at AMNH working on a manta ray specimen in 1917:   Woah, right?  Helluva fish.  Well, hold your horses there, Tex.  It’s actually a model.  I was a bit suspicious that the specimen was just so…perfect…so I dug around […]

Brutal Battle Between Great White Sharks? Not really, no.

The following post is Luiz Rocha, Associate Curator and Follett Chair of Ichthyology at the California Academy of Sciences. His major research interests include evolution, conservation, taxonomy, and community ecology of coral reef fishes.The...Show More Summary

Are swimming zooplankton driving ocean currents? Sort of.

Biomixing, where the ocean is mixed by swimming animals, has long been a hot topic in oceanography. Some people think all that biological flapping and stroking could be a major source of oceanic turbulence. Others, not so much. But a new laboratory study by M. Wilhelmus and J. Dabiri from Caltech is certainly going to ignite scientists love […]

A story about fish, plastic debris and sex

This is a guest post by Chelsea Rochman. Chelsea is a post-doc at the University of California Davis. This is her fourth guest post at DSN, and the first one to come with this.  WARNING: Some content may not be acceptable for a younger audience. (Note from Miriam: It’s ok, Chelsea, nothing in this post is at all out of […]

Symphonies of the Sea

I am inspired by the sea. Inspired to understand the way it moves, meanders, ebbs, flows, heaves, and crashes. Others are inspired by the sea to create. Inspired to dance, draw, perform, paint, and compose. It is this last genre that I want to highlight with a selection of ocean-inspired symphonies. I like to think of them as bringing all the ocean to […]

Diagnosing Death with Diatoms

“I know you drowned him in the ocean, these bones don’t lie…” Ever heard of forensic limnology? Neither had I, until I had a random conversation during a coffee break. The police find a body in the water. How did it get there? How did this person actually die? Was this a tragic accident, or […]

ZOMG Whale shark attack!!!! Or not…

So this little gem came across my Google alerts today. The cognitive dissonance between what happens (biologically) in that video, what the two intrepid heroes do, and what’s reported, fills me with dismay for society.  If that seems hyperbolic, bear with me.  Let’s break it down: What the story says Benchley-esque narrative: blah blah “terrifying […]
