Do you want to learn how to draw fish, sharks and other sea creatures? Let’s take a look at the anatomy of the fish and learn what differentiate the several types of fish in order to create beautiful drawings of fish or even mermaids!
There are more than 20,000 types of fish, but many of them share the same characteristics. The easiest way to learn how to draw fish is by drawing it in profile and dividing the fish body into three parts: its body, usually torpedo-shaped (known as fusiform), but also worm or eel-shaped, the fish head and tail on opposite sides of the body.
How to Draw Fish Scales
The fish body is usually covered with scales. The scales purpose is to protect the fish. The fish scales are divided into four groups:
Cycloid scales, with round and smooth edges
Ctenoid scales, with comb-teeth edges
Ganoid scales, thick and bony scales with glossy covering
Placoid scales, the tough and bony scales that cover the body of sharks and rays
The most common fish scales are Cycloid and Ctenoid, and we would usually draw them when making fish drawings.
Fish also have fins in different shapes. The fins’ purpose is to support the fish stance and movement and many fish have stiff rays for protection. The fish fins differ in their shapes and locations on the fish body:
Dorsal fin – an irregular fin located on the fish body, which can be singe or divided in two.
Anal fin – located next to the tail on the fish bottom
Pectoral fins – located near the fish head, on both sides of the body
Pelvic fins – near the head, on both sides of the body
Caudal fin – near the tail
Ventral fin – near the underbelly
Based on these basic fish drawing characteristics, you can draw fish in many forms, sizes and colors and create beautiful artworks of fish and marine life.
