What is a rising sea level and how does it effect us?

Basically, rising sea levels affects coastal areas the most drastically. But, don’t dismay! The EPA, […]
Can a sea star see?

Sea stars (Sidenote: since they are not ‘fish’ sea stars, as opposed to starfish, is more appropriate) have an eyespot at the tip of each “leg”. These eyespots can distinguish between light and dark and other stimuli and the […]
10 tips for a successful beachcombing trip
It’s my favorite time of year. This is the best time to explore the beach. It’s still sunny and warm, there are frequent storms (you’ll see why that matters later), and there are few people on the beach.

I hope I have created a place where questions on anything from barnacles to whales can be answered in a knowledgeable no-nonsense or overly jargon tone. My secondary goal has also been […]

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 […]
