How And Why Seahorses Change Colour

Seahorses change colour primarily by controlling pigment cells called chromatophores.

They have small, sac-like organs called chromatophores embedded in their skin, each containing one or more pigments.

When the muscles expand the chromatophore, the colour is bright and clear.

When they contract it, the pigment gathers in one spot, and the colour becomes muted or disappears.

As poor swimmers, the main reason for colour change is to blend in with their environment to hide from predators and ambush prey.

For example, seahorses in seagrass beds tend to be green, while those in coral reefs may display brighter hues of orange, red, or yellow.

During elaborate daily greeting rituals and courtship displays, both males and females will change colour.

Colouration can also reflect a seahorse's general mood, health, and stress levels.
