Cuba’s Enigmatic Callonia Snail: Scaled Funnel Shell Redefines Mollusk Morphology
Endemic to Cuba’s mist-shrouded mountain ranges, the Callonia snail (genus Callonia) perplexes biologists with its scale-covered, funnel-shaped shell—an evolutionary departure unmatched in the mollusk kingdom. Discovered in the 1930s, this rare gastropod thrives in cloud forests above 1,000 meters, its unique form hinting at adaptations to Cuba’s karst landscapes. Though poorly studied, its striking shell has become a symbol of island biodiversity under threat.
Ecuador’s 'Popcorn Bug': Flying Planthopper Nymphs Defy Predators with Waxy Camouflage
Deep in Ecuador’s cloud forests, a tiny insect nicknamed the "popcorn bug" has captivated scientists with its uncanny resemblance to a flying kernel of popcorn.
