Reef Science

Coral Reef Ecology: Life, Chemistry & Connection

There's a reef in this house — three of them, actually — and this fall, your student can help tend it.

This isn't a class about the ocean from a textbook. It's a class in one. Students will get their hands into real reef tank maintenance, test the water chemistry that keeps coral alive, and sit with sketchbooks in hand, observing living specimens the way field biologists do — slowing down enough to really see the animal in front of them.

Coral looks simple from the surface, but a reef is one of the most densely interconnected ecosystems on Earth. Inside every coral polyp lives an algae partner it can't survive without. Around and within the coral structure itself, fish shelter, feed, and raise their young — a whole neighborhood built into a single organism. Students will learn to identify coral by species, untangle the web of relationships that make reef life possible, and see firsthand how fragile that balance is when ocean chemistry shifts.

From there, we zoom out: how does a warming ocean half a world away change a reef? And who's working to stop it — the university labs, aquariums, and nonprofit "coral banks" propagating threatened species to keep reef diversity alive for the future.

Held partly in our home tank room and partly outdoors on the deck, this is an intimate, hands-on class — small enough for real mentorship, real questions, and real time with the animals themselves.
