Big porpoise energy
The vaquita, the world's smallest and most endangered porpoise, is teetering on extinction—yet its plight has sparked unprecedented global attention, revealing a paradox in conservation: we save species we love, not necessarily those most in need. In this episode, host Nate Hedgie dives into the overlooked world of porpoises, contrasting their stealthy, high-speed, high-metabolism biology with the adoration reserved for whales and dolphins. He explores the vaquita’s tragic decline due to illegal gill net fishing for prized shrimp and the totoaba bladder—a product worth more than gold. Despite failed bans and ghost nets, Sea Shepherd’s direct action has helped stabilize the population. But the real revelation? The vaquita’s survival hinges on its cuteness. As Hedgie admits, we’re drawn to charismatic megafauna, even if it means neglecting less glamorous species like sea snails or desert flowers. The episode ends with a bittersweet truth: saving the vaquita may be possible, but only because it’s adorable—raising urgent questions about whether conservation should be driven by emotion or equity. The episode also unpacks the science behind porpoise speed, echolocation, and mating behavior, revealing the doll's porpoise as the Olympic sprinter of the sea, capable of 34 mph. Porpoises use ultra-high-frequency clicks beyond human hearing, making them nearly invisible to both predators and observers.
The vaquita, the world's smallest porpoise, has fewer than 10 individuals left due to illegal gill net fishing for totoaba bladders, which sell for more than gold.
Porpoises use ultra-high-frequency echolocation (up to 130 kHz), six times higher than human hearing, making them nearly undetectable to both predators and researchers.
The doll's porpoise can swim at 34 mph—faster than Usain Bolt and a common dolphin riding ship waves—making it the Olympic sprinter of the sea.
Harbor porpoises have an extreme penis-to-body ratio, and their mating involves aerial leaps, suggesting evolutionary adaptations for speed and reproductive success.
Despite being overlooked, porpoises are not dolphins—taxonomically, they’re more distantly related to dolphins than humans are to gorillas.

“The doll's porpoise lives in the North Pacific. It's been clocked free swimming at 34 miles per hour. That is way faster than Usain Bolt.”
The Porpoise Paradox: Why We Don’t See Them
The host explains why porpoises are so hard to spot—small dorsal fins, duck-like silhouettes, and a shy nature. He contrasts them with dolphins, which are social, showy, and interactive.
Predators and Porpoicide: Life in the Fast Lane
“Dolphins and porpoises, they eat different kinds of seafood. Instead, their best guess was that it was the height of dolphin breeding season and some testosterone-addled dolphin bros were killing porpoises just for fun.”
“And one thing that really stuck with me in my reporting is a gram of totoaba bladder is worth way more than a gram of gold.”

“thing for charismatic species, you know? Like, I look at the vaquita and it's like, you know, it reminds me of my pet or something.”
