White-Speckled Seahare

Aplysia argus

Aplysia argus is a small gastropod mollusc characterized by its olive-colored body adorned with eye-like ocellated spots. These spots consist of a whitish center surrounded by a dark-brown margin. This species can grow up to 8 inches in length and is often confused with Aplysia dactylomela due to their morphological similarities. However, genetic studies confirm that Aplysia argus is distinct and native to the Indo-Pacific region, including areas such as the Hawaiian Islands and French Frigate Shoals. They typically inhabit shallow pools surrounded by rocks at depths ranging from three to six feet, where they can be found hiding during the day, as they are nocturnal creatures. Most sea hares remain close to their egg masses, which adds to their localized presence in these habitats. Encountering Aplysia argus while diving can be intriguing, as they often blend into their surroundings, making them somewhat cryptic. Their conservation status has not been evaluated, but they are generally considered harmless to humans.
