The seaweeds have formations like leaves and roots unlike territorial plants.

They can be seen on the rock pools in the coastal regions. They are separated to three basic groups according to their pigments; green, brown and red algae.

Caulerpa racemosa has seen in the Gökçeada Underwater Marine Park:
This species entered to the Mediterranean Sea via Suez Canal, and in the following years it spread to North Aegean Sea.

Caulerpa racemosa is in a green algae, bright green in color that easily adaptates to warmer waters due to global warming. It prevents the living of other species by excreting the toxic madde called Caulerpenin.
As a result of the boat anchorings in the bays, the anchors remove the sea grasses from the bottom and opens new gaps between the seagrass beds. Caulerpa racemosa can spread easily in these gaps.
