GIRLY JUST FOUND OUT ABOUT CYERCE ELEGANS

If Cyerce nigricans is a butterfly, then this is a fairy... Cyerce nigricans for comparison:

Make way for the granulated sea star (Choriaster granulatus)! Growing to about 10 in (25 cm) in size, it's also known as the “doughboy starfish” for its portly look. This species hangs out around reef habitats in shallow Indo-Pacific waters. On its menu are coral and other small invertebrates—it sometimes even scavenges dead animals.

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).

COMMON STARFISH

Asterias rubens

PHYLUM ECHINODERMATA

CLASS ASTEROIDEA

It feeds on benthic (seafloor-dwelling) organisms such as molluscs, worms, and other echinoderms. It is predated by other starfish, snails, crabs, and fish underwater, and by seabirds when stranded ashore.

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.
