Mammal

High in a South American rainforest canopy, scientists have discovered a bizarre new termite species that looks strikingly like a miniature sperm whale. Named Cryptotermes mobydicki, this tiny insect has an elongated head and concealed mandibles that give it an uncanny resemblance to the iconic marine giant. Researchers were so surprised by its unusual appearance that they initially thought it belonged to an entirely new genus.

Old canned salmon turned out to be a time capsule of ocean health. Researchers found that rising levels of tiny parasitic worms in some salmon species suggest stronger, more complete marine food webs. Because these parasites depend on multiple hosts—including marine mammals—their increase may reflect ecosystem recovery over decades. What looks unappetizing may actually be a sign of a healthier ocean.

A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting off their routes. Hundreds of species now need coordinated international protection. Experts say restoring river connectivity is critical to preventing further collapse.

Snow flies have an unexpected way of surviving freezing temperatures. They produce antifreeze proteins to block ice formation and can even generate their own heat. Scientists also found that their genes are unusually unique, and they feel less cold-related pain than other insects. These combined traits let them stay active in conditions that would freeze most species.

Flower nectar often contains small amounts of alcohol, meaning pollinators like hummingbirds are drinking it all day long. Despite consuming human-equivalent amounts, they show no signs of intoxication—suggesting a surprising evolutionary tolerance.
