Do all jellies sting?
Yes, they do. All jellies have specialized structures called cnidoblasts. Inside the cnidoblasts are capsules called nematocysts. Inside each nematocyst is a coiled, hollow thread. Nematocysts are triggered by mechanical (touch) or chemical stimuli. When they fire, the thread turns inside out, pierces its prey and delivers its venom. A jelly’s tentacles and oral arms […]
Do you know your seafood?
With the holidays right around the corner there will no doubt be plenty of indulgences. It is important to keep in mind that seafood can also be considered an extravagance if you’re choosing an unsustainable option to serve or taste. Did you know that the global fishing fleet can catch up to two and a […]
Sea slug actually anything but a lug
This might sound familiar (since I recently retweeted from @NOAAOceanToday) but there was recently an article discussing the virtues of sea slugs. In particular that they have been used to understand how to maximize the effectiveness of long-term memory in humans. Also, check out these divers (with the Bamfield Marine Sciences Centre in Bamfield, BC) […]
Does the ocean freeze?
That all depends upon the salinity of the water. For more information about salinity, or how much salt is in the ocean, click here. Generally the higher the salinity the lower the freezing point. So the ocean of the Mid-Atlantic, with an average salinity of 32 ppt, doesn’t tend to freeze when the rain turns […]

5 things you might not know about oarfish
Last week 2 giant, shimmering oarfish washed ashore in southern California. This is not a common occurrence and some speculate that it may be a means to warn of an impending earthquake. Others say that it could just be a “banner week for weird fish photo ops“. In either case, I’m making the most of […]
12 truths about diamondback terrapins (please, see #8)
Each diamondback terrapin is a work of art. Their skin color ranges from pale to dark gray, or even black. The underside of their shell (plastron) ranges from yellow to green, or even black. But, those variations aren’t the reason for its name. If have the opportunity, be sure to check out the mesmerizing diamond-shaped […]
Horseshoe crabs confirmed as members of arachnid family
Even though they have ten legs – not, eight – we’ve always said horseshoe crabs are members of the arachnid family. It was first theorized by E. Ray Lankester in 1881. But, until recently, it had not been proven in terms of genetics. Scientists at the University of Wisconsin-Madison studied the molecular evolutionary patterns of […]
Who owns the fish in the sea?
It takes at least five minutes of discussion between a grandfather and a grandson to explain who owns the ocean and who can fish in the U.S. seas. Check out this animated video produced by the Center for Investigative Reporting as they share their perspective on the catch shares system in which “the right to […]
Basics on renewable energy
This weekend, I went to the demonstration “Hands Across the Sand”. The intent was to declare to President Obama that we demand clean energy and request a stop to offshore drilling (which he promised to do during his campaign). With all that said, my husband kept telling my mother-in-law that I was going to a […]
