Albino Harlequin Star

The Albino Harlequin Star (Astropecten sp.) is a striking starfish prized for its bright white coloration and elegant arm structure. This albino variant stands out among typical Harlequin Stars and is a popular species in marine aquariums due to its rare and attractive appearance.

Coloration:

Predominantly white or cream, sometimes showing faint yellow or pink spots. Its pale albino look can appear almost translucent under aquarium lighting.

Typical Size and Abundance:

• Average size: 4-6  inches in diameter, occasionally reaching up to 12"

• Abundance: Moderately common in the wild, but the albino form is rare compared to pigmented counterparts.

Behavior and Aggressiveness:

• Generally calm and non-aggressive.

• May be slightly territorial toward other starfish if space is limited.

Reproduction and Sexuality:

• Sexual reproduction predominates; gametes are released into the water.

• Usually not hermaphroditic, with separate male and female individuals.

Toxicity:

• Non-venomous; safe for community aquariums but preys on small invertebrates.

Care Difficulty:

• Moderate. Requires stable water parameters, clean substrate, and access to suitable food. Sensitive to poor water quality and sudden changes, making careful maintenance important.

Fun Facts:

1. The albino variant is rare, making it a prized find for collectors.

2. It hunts by using its arms to trap small invertebrates on the seafloor.

3. Like many starfish, it can regenerate lost arms, and occasionally an arm can regrow into a full starfish.

4. Mostly nocturnal, hiding during the day to avoid predators.

5. Despite its albino coloration, it can blend with sandy tropical seafloors.

6. Its sensitivity to water quality makes it an indicator of reef health.
