Veliger is the stage of a mollusk’s life prior to it becoming an adult. This is after it goes through the trochophore larva stage. During the veliger stage a mollusk develops its swimming membrane. Image (c) pbs.org
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. […]
Jellies don’t technically float; they’re neutrally buoyant (or close to it). Floating would be bad. It would mean being stuck on the surface, like a boat. Jellies are mostly water-up to 96%. What’s left is mostly the “jelly” in a jellyfish, the mesoglea. Jellies sink exceedingly slowly, and make up for it with just a […]
“As iron sharpens iron, so a friend sharpens a friend.” King Solomon There is not a lot life down in the deep sea. Fortunately, it is convenient that the hydrothermal vents down there share a wealth of minerals to the otherwise desolate neighborhood. More notably what was just uncovered is that iron particles (known as […]
Happy Tuesday! I am sure you know by now, but this is a series I have been featuring each Tuesday this summer to get a special sneak peek at the different personalities behind the scientists, activists, and educators (including bloggers) who play an integral role in the marine science conservation field. It’s essentially an extension […]
There are plenty of candidates. The deep-diving, plankton-feeding megamouth shark was discovered as recently as 1976 and is only known from 40 or so specimens. A group of species called “river sharks” seem pretty rare. Some have been described from just a single collected specimen. There are many deep sea sharks that have only been […]
Some species of fish can regulate their salt tolerance easier than others. For instance, many of the species that call the estuary a nursery or breeding ground can adapt to a wide range of salinity (less than 30 ppt). These animals (or plants) are known as euryhaline. Other animals that cannot tolerate a wide range […]
In honor of St. Patrick’s Day, and my Irish heritage, here’s a post on the humble and charming sea potato. The dried shell (also known as the test) of this urchin resembles a potato, hence the common name – sea potato. The sea potato, Echinocardium cordatum, is a common echinoderm found along beaches on all […]
An arenophile is someone that collects sand specimens from different beaches. Not to be confused with a person that loves aviation – an areophile. But we’ve only scratched the surface here. Check back often at http://www.beachchairscientist.com for more insight about your favorite beach discoveries.
Today Ira Flatow discussed summer science reads on Science Friday, my favorite radio program. So, I got to thinking about two very special books that I always wander back to when I want to reconnect with the ocean. Henry Beston’s, The Outermost House, and Jennifer Ackerman’s, Notes from the Shore, are two books written in […]
