The shape of a fish's caudal tail can tell you a lot about how fast the fish moves! A rounded tail is the slowest and a lunate tail is the fastest! The lunate tail has the most optimal ratio of high thrust and low draw, making it the fastest.

Fish anatomy!

Fishes have a great number of fins, which help them balance themselves and move around their environment. Some fish have fins that are highly specialised for certain tasks, for example the elongated and large pectoral fins of a flying fish allow them to glide and the pelvic fins of gobies tend to be fused together to form a suction disc!

sturgeon fun fact, their skeleton is made mainly out of cartilage like sharks, but they’re still classified as bony fish. also they don’t have scales like most fish, instead they have skin, and armoured plates called scutes, which run in five lines down the length of their body. also they have no teeth, instead they use their mouth as a vacuum to suck up food from the gravel and substrate of the bottom of their riverine habitat, and also (again) they have four barbels (thin sensory organs - think of catfish’s whiskers) that precede their mouths, which they drag along the bed as they swim to help locate food. yeah their anatomy is pretty sick.

Who would have thought fish had so many bones just in their skulls? Luckily I have Ragnar to keep me sane while I cry over bones and parts of bones and what they do
