1. Algae, first link in the food chain

Laminaria Algae floating on the surface.

Like plants, algae use mineral salts, water, carbon dioxide and sunlight to grow. They are producers. Some species are microscopic while others can grow to several meters in length.

2. Urchin, the herbivore

Sea ​​urchin on submerged rocks

This herbivore is not dangerous but be careful, it’s prickly! It feeds on algae, such as kelp, using the small teeth located on its underside. Since it does not eat other animals, it’s called a primary consumer.

3. Common rock crab

Always ready to attack, it fights its fellow crabs for food. Its two front claws are impressive tools for breaking the shells of its prey. The common rock crab feeds mainly on animals, making it a secondary consumer.

4. Atlantic cod

Among fish, the biggest often eat the smallest. The Atlantic cod hunts in the deep, in the dark, using its chin barbel to detect fish and crustaceans hiding in the mud. Carnivorous fish like the cod eat only animals. Omnivorous fish feed on animal and algae.

5. Harbour seal

Harbour seal's head.

We say it has a horse-shaped head but with its flippers, it’s called a pinniped. Using its very sensitive whiskers, the harbour seal is able to detect its prey (fish, crustacean, mollusc) in total darkness. It’s a carnivore.

6. Whelk

Common whelk on the seabed

The whelk feeds mainly on dead animal it finds on the sea floor using its siphon-shaped nose. Despite its somewhat unappetizing diet, the whelk’s white flesh is excellent to eat.
