Did you know some species of puffers and other fish can live in both fresh and saltwater? It’s called euryhaline. Like … rhymes with “your-e-hey-leen!”. What’s it called when an animal isn’t this adaptable? Find out here.

The Cove
The Oscars are this Sunday and there is one documentary which you may want to check out. I have posted a review of “The Cove” by Kenneth Turran, a film and book critic for the Los Angeles Times. Have you already watched the film? I would love to know what you think.
An important call for more forage fish to remain in the sea
A report titled “Little Fish Big Impact”, written by the Lenfest Forage Fish Task Force, came out earlier this month recommending that the amount of forage fish (e.g., menhaden, herring, shad) that we take from the ocean should be cut in half. However, since forage fish have an annual value world-wide of $5.6 billion dollars […]
Holy, mole(y) crab!
Mole crabs are recognizable decapods with their barrel-shaped bodies and a grey colored exoskeleton and known to many of us as ‘sand fleas’. We often only see them for a wee bit when a wave (or curious hand playing in the sand) dislodges them and they quickly scurry back under the sand. These clawless crabs […]
Happy Chinese New Year … Year of the (Sea) Dragon!
Happy Chinese New Year … Year of the (Sea) Dragon! January 23 will bring a very significant celebration for those that live by the sea … it is the year of the water dragon which only occurs every six decades! To commemorate such an occasion, BCS will highlight two very remarkable and elaborate dragons found […]
5 on-the-ground warriors for marine debris
I’ll be incredibly frank and honest and say that I do not do as much on-the-ground ocean activism as I’d like to do these days. I do participate the occasion stream clean-up and rally from time to time, but with a full-time job and a family including an active toddler, time is scarce and I’m […]
How do fish float?
Bony fish have a swim bladder, a gas filled sac. The swim bladder originates as part of the belly. The swim bladder aids in creating an equilibrium with what is going on inside the fish and the surrounding water. Some fish have a bladder that is part of the respiratory system, called an air bladder. […]
What do sand sharks eat?
“Sand shark” can be a bit of a catch-all term, but it seems to most commonly refer to the sand tiger shark, Charcharius taurus. Sand tigers are an interesting case study in form following function in shark teeth. Sand tigers have long, narrow, prong-shaped teeth—like the tines of a fork. Their teeth are perfectly shaped […]
My favorite posts from 2012
This isn’t the typical list of the most popular Beach Chair Scientist posts throughout the year. Those posts typically include questions typed into a search bar such as ‘Do sharks have bones?’ or ‘How much salt is in the ocean?’. Not surprisingly, my favorite posts aren’t focused on straight up interpretation, but rather have more […]
Christmas critter countdown: Christmas tree worm
Admittedly, at this point my kind readers know that I’m a nut over some ocean humor (despite the rolling eyes from loved ones!). So if you’ll indulge me this holiday season I now have a list of twelve ornamental-appropriate organisms. My first one to share is the Christmas tree worm. The Christmas tree worm, found […]
Are flounder born flat?
They hatch from the egg looking exactly like typical fish, swimming in the upper waters. After two weeks the bridge of the fish’s nose fades away and then one of the eyes, depending on the species, shifts to one side. The process of becoming a complete “flat” fish takes a bit of time, but, once […]
