The wonder of small things

From a public perspective, biology in the oceans, like biology on the land, tends to favor the charismatic megafauna. Stop by your local aquarium and you'll find masses huddled around the seal pool or the shark tank. People will even attempt to interact with the octopodes. Meanwhile, smaller creatures sit on the sidelines. Crabs, starfish, and ray-like skates have some admirers at the touch tanks. But in the world of small things, they're actually quite large. The ocean is full of even tinier organisms—worms and snails, small shelled animals and even stationary colonies of life that look like rocks or lumps of sand.

The ocean is an amazing place, and Bill Grossman can tell you about the things that live there—large, small, or tiny. Grossman is specimen collector for the Marine Biological Laboratory. Essentially, he's part of a system of support staff for scientists. When researchers at MBL need sea creatures to study, it's people like Grossman who go out on the water and find them.

Back in May, I got to take a short trip aboard the R/V Gemma, MBL's specimen collection boat. The videos I brought back can teach you some amazing things about animals you thought you knew well, and introduce you to creatures you probably never noticed before. Read the rest
