Tripod Fish (Bathypterois sp.)
Bathypterois is a genus deep sea fish known as the tripod fish. As their name suggests, the fish stands on the sea floor using three fins as support. In some species, these fins can be up to 1m long.
The fish perch on the substrate with their heads facing the current. The fins allow for their heads to be at the right level to catch drifting crustaceans and small fish.
Due to the complete darkness of the deep sea, the fish does not rely on eyesight to catch prey. Instead, it faces its pectoral fins forward and uses tactile and mechanosensory cues to identify food. Once they feel prey and realise it is edible, the fins sweep the food into the fish’s mouth.
Impossible to ride a square-wheeled bike?
Maybe hard to believe, but square wheels can move smoothly (with their axles in a straight line and at a constant velocity), if they roll over evenly spaced bumps in the shape of an inverted catenary.
Not only squares, but also lots of other interesting shapes can be used as wheel, as long as the shape of the road is appropriate. For instance, for cardioid-shaped wheels you need cycloid-shaped roads:
It’s not about reinventing the wheel, it’s about reinventing the road.
