A Serendipitous Song-Dog in Yellowstone

On March 1, 2022, Yellowstone National Park celebrated its 150th anniversary. I was privileged to work briefly for the Park Service there after college, and Elise and I make a point of returning every year; our honeymoon even revolved around a backpacking trip up Slough and Pebble Creeks. Until we visited last February to cross-country […]

Some crowd-sourced reflections on E.O. Wilson and Tom Lovejoy

Just before the turn of the new year, E.O. Wilson and Tom Lovejoy, two of the world’s most celebrated biologists, passed away within a day of each other. That they left the world together felt fitting, given the extraordinary interplay between their work. It was Wilson, after all, who, in a series of mad, ingenious […]

What Do We Owe Our Octopus Teachers?

Two weeks ago, late to the zeitgeist as ever, I watched My Octopus Teacher, the Oscar-winning documentary about a relationship between a human and a cephalopod. Probably you’ve seen it (and if not, you should!), but, in brief, it’s about the yearlong friendship filmmaker Craig Foster strikes up with a female common octopus who lives […]

Snapshot: Uncommon Dolphin

A couple years back, during a day cruise around the Channel Islands, we found ourselves surrounded by a sizable school of common dolphins. (Not a mega-pod, alas, but even a few dozen dolphins is a pretty awe-inspiring sight.) Common dolphins are, as their name suggests, among the most abundant marine mammals in the world; it’s […]

How Baby Snoots Became the World’s Most Famous Manatee

For a recent edition of Smithsonian Magazine, I wrote a retrospective on the life and career of Marie Fish — ichthyologist, bioacoustician, and epitome of nominative determinism. Fish spent decades recording marine animals in her laboratory and at sea, and revealed that, far from being the “silent world” described by Jacques Cousteau, the ocean was […]
