There are four types of fish scales!

Cycloid scales are thin, overlap, and flexible. They're found on primitive teleosts (like minnows and carp).

Ctenoid scales have small, backwards pointed scales (known as cterns) make the fish more hydrodynamic and faster. They're found on Advanced Ctenoids (like perch and sunfish).

Ganoid scales are thick, diamond-shaped, and mostly non-overlapping. They're found on Chondrostei (like sturgeons and paddlefish).

Placoid scales are spikey and tooth-like with nerves. These are found on Chondrichthyes (like sharks and rays).

Here are some of the sturgeon photos I promised from ages ago. This was at the Bonneville hatchery where they house Herman the sturgeon. He's proported to be 90 years old and 14ft long, but it's a title now and the one we saw wasn't the same fish as the original Herman. But the fish we saw WAS between 80-90 years old due to his size, according to his caretakers.

He's the big pale fellow in the far back of the pool. I'm his biggest fan istg. I got so much merch after crying like a baby at the joy of seeing these amazing fish.

A helpful guide for learning the difference between Green Sturgeon and White Sturgeon. Although Green Sturgeon are a good bit harder to find, so consider yourself lucky if you have this dilemma.
