What you need to know about World Shorebirds Day: Saturday, September 6th

Then, once the bivalve’s shell is open, the stomach of the sea star emerges from the middle of the underside of its star-shaped body to absorb the […]
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 […]
What are skates and how are they different from rays?
Recently, a subscriber wanted to learn more about skates. Great question since many of us think of ‘roller’ when we think ‘skate’. Skates are a species that often get overshadowed by rays, especially considering rays tend to be boldly colored while skates tend to be rather dreary and drab in coloration. Rays are also found […]
