Octopi this …
In honor of the Beatles (on today the 10th anniversary of George Harrison‘s death) I thought I would feature the incredibly intelligent animal from one of my favorite songs, Octopus’s Garden. The song (released in the US on September 1, 1969) was the second song written by Ringo Starr for The Beatles (but, as my […]
It’s as easy as A, B, Sea: L for Limpet
Limpets are small, flattened snails with a conical shell that live on rocks in the intertidal zone. They trap water beneath their shell and use it to survive from high tide to low tide. Image (c) wordsmith.org
Why is the blood of horseshoe crabs blue?
Horseshoe crabs use hemocyanin to distribute oxygen throughout their bodies. Hemocyanin is copper-based and gives the animal its distinctive blue blood. We use an iron-based hemoglobin to move oxygen around. The blood of this living fossil has the ability to clot in an instance when it detects unfamiliar germs, therefore building up protective barriers to […]
How is it I can find some species of fish in fresh and saltwater?
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 […]
Have you watched Ocean Frontiers yet?
Ocean Frontiers is a movie you cannot miss the opportunity to watch. If not because you are genuinely interested in a film that outlines the transition of thought from the “the outlook is grim for the future of the ocean” to “there is a light at the end of the tunnel for our ocean“, then […]
Nudibranchs: The elusive butterflies of the sea
The 3,000 species of nudibranchs (noo-duh-brangk) boast more colors than a box of Crayola crayons and most nudibranchs “live no more than a year and then disappear without a trace, their boneless, shell-less bodies leaving no record of their brief, brilliant lives”. These sea slugs are found all over the world and range in size […]
How do sandbars get started?
The current closest to the ocean floor is moving offshore and dumps small piles of sand right at the wave break area. The sand accumulates to various degrees, and regardless it makes the water much shallower where you stand. Now, the sandbars that I am thinking of are very long and are parallel to the […]

What is a salt marsh?
A salt marsh is the habitat where freshwater (from rivers and lakes) mixes with the saltwater (from the ocean). The salt marshes that I am most familiar with have tall cordgrasses near the water’s edge. Usually, it is a mix of two types of cordgrass, Spartina alterniflora and Spartina pattens. Away from the water’s edge […]
