This isn’t just another nudibranch. It’s a tethyid “hooded” sea slug with a massive expandable oral hood that functions like an underwater Venus flytrap. Here’s why it’s wild 👇 🧠 No shell. No problem. Like other nudibranchs, it ditched its shell entirely. Instead, it relies on transparency, camouflage, and chemical defenses. 🪤 A collapsible capture net. Its hood isn’t a mouth in the traditional sense. It’s a muscular, tentacle-lined feeding basket. When tiny crustaceans swim inside, the hood snaps shut in milliseconds. ⚡ Neural simplicity, complex behavior. Despite having a relatively simple nervous system (compared to vertebrates), it coordinates rapid prey capture using distributed ganglia (clusters of neurons). Studying this helps researchers understand how small neural circuits generate behavior. 🧪 Chemical warfare. Many nudibranchs sequester toxins from prey like hydroids. Some species can even synthesize defensive compounds. These molecules are of interest in pharmacolog...
