Researchers have confirmed the rediscovery of the pink handfish (Brachiopsilus dianthus) off the coasts of Tasmania. This species, last seen more than two decades ago, has modified pectoral fins that allow it to walk on the marine substrate. Its movement is distinct from conventional swimming, an adaptation for moving along the ocean floor where it lives.
Biomimetics: when engineering is inspired by underwater locomotion 🤖
The locomotion of this fish poses a case study for underwater robotics. Traditional remotely operated vehicles (ROVs) use propellers, which can stir up sediments and reduce visibility. A design inspired by this underwater walk could offer stable mobility on complex bottoms with less environmental disturbance. Analyzing the mechanics of its fins provides data for creating exploration robots with more efficient and discreet movement.
The fish that gave up swimming to go on foot for work 👣
While other fish glide elegantly through the water column, this one decided that walking was an option. Imagine its day: without the rush to get anywhere, strolling along the seabed as if window shopping. Maybe it thinks swimming is too common, and prefers the terrestrial method, even if it takes longer. A clear case of extreme specialization, like someone who masters obsolete software that no one else knows how to use.
