Mudskipper is a fish which spend more time on land than in water. In fact, a mudskipper will drown if it’s never able to reach the water’s surface! Like other fish, mudskippers breathe through gills, but in addition they absorb oxygen through their skin and the linings of their mouths and throats. They are able to move over land by using their pectoral fins to pull themselves forward, or they perform a series of skips or jumps. Pokemon “Mudkip” is based on this fish.
Bumbling bumblers from my hive mind.
Species in the Rhinochimaera family are known as long-nosed chimaeras. Their unusually long snouts (compared to other chimaeras) have sensory nerves that allow the fish to find food. Also, their first dorsal fin contains a mildly venomous spine that is used defensively. They are found in deep, temperate and tropical waters between 200 to 2,000 m in depth, and can grow to be up to 140 cm (4.5 ft) in length.
Chimaeras (also known as ghost sharks and ratfish) are an order of cartilaginous fish most closely related to sharks, but they have been evolutionarily isolated from them for over 400 million years.
It’s in tiny little type there so I’ll just go ahead and repeat: this is NOT an animation. If you’ve got 2 minutes it’s worth watching the full video.
Hey, c’mon, stop that.
Yippee, my first animations in Mathematica!
Let a circle roll around a circle twice as big. The shape traced by a point on the outer circle is a cardioid. Now consider a third circle rolling around the second one as well (again half as big, and at the same speed); its trace is already less familiar. The more circles, the more fractal-ish the resulting curve will be. In the limit, the traced curve can be described with this parametric formula:
