What Does a Northern Pike Look Like?
From the image below, you can see that the Northern Pike has a long body shape. This makes it a fast swimmer, and good predator.
Its body is covered in small scales which are usually an olive green colour, and become paler on its belly. Although northern pike are usually olive, they can also have grey or pinkish-red colors on their backs.
Head and Eyes
The Northern Pike has a very distinctive looking head with large eyes that are disproportionally big compared to its body size.
Its head has a bony looking appearance, and its eyes are just above the snout. Pike have very good eyesight to detect their prey, and their eyes are forward facing which helps them to judge distance.
Teeth and Mouth
The Northern Pike has a duck-billed shaped snout with a large mouth. It is an apex predator, which means it’s at the top of the food chain without any predators of its own. Apex predators have strong and sharp teeth to catch their prey.
A pike’s mouth can have up to 700 teeth. The teeth are various sizes, and usually long and sharp. Very large pike can even have teeth that are up to 1 inch in length on the lower jaw.
The Northern Pike has a single dorsal fin and anal fin each near the tail. It also has two pairs of fins near the head and stomach.
The fins are a different colour from the rest of the body, and are usually red or brown. They can also have dark lines or spots on them. The diagram below will help you identify the dorsal and anal fins.
What Colour is a Pike?
Pikes are olive green coloured with creamy blotches. You can see from the photograph below the pike’s back is dark green and its belly is white. It has orange fins with dark patterns, and bright orange on its tail.
How Big do Pike Get?
Larger pikes can grow to over 1 metre in length and weigh up to 30kg. The largest pike ever caught was 161.29 cm long, and weighed 30.61 kg. It was found in Wisconsin in the United States.

American pickerel, chain pickerel, and muskellunges are all species of fish in the same genus as the Northern pike, and have similar characteristics. They all have long slender bodies and markings on their backs. They also have the same duckbill-shaped snouts.

Adult pike leave their eggs in shallow water. After the eggs hatch, the baby pike remain in the shallow water until they are around three inches long, before moving to deeper water.
