The olive rockfish (scientific name: Acanthoclinus fuscus) is a special fish that lives in the ocean. It belongs to a group of fish called longfins, which are part of the Plesiopidae family. These fish are only found in New Zealand. They live in the areas along the coast where the ocean meets the land, called the intertidal zone. You can often spot them in rock pools when the tide is low.

About the Olive Rockfish
Olive rockfish can grow up to 30 cm (12 in) long. They are permanent residents of the intertidal zone. This means they usually stay in the same area. They are known for their "homing behaviour," which means they can find their way back to their favorite rock pools. They live among rocks or boulders. If the water in their pool becomes too warm or too dirty, they can leave and find a better spot.
What They Eat
Olive rockfish are not picky eaters! Their diet mainly consists of small ocean creatures without backbones, called invertebrates. They especially love to eat crustaceans, like tiny crabs or shrimp, and molluscs, such as small snails or clams.
Cool Abilities
These fish have some amazing abilities! They can actually breathe air, which helps them survive if they get stuck out of water for a short time. They also swim in a unique way, moving their bodies like an eel. This wavy motion helps them glide through the water.
Reproduction and Family Life
When it's time to lay eggs, the male olive rockfish takes on an important job. He guards the eggs carefully until they hatch. This helps protect the young fish from predators.
Appearance
Olive rockfish are usually black. They have a special white band on their head that helps you tell them apart from other fish.
