Geographic Seahare

Syphonota geographica

Syphonota geographica is a unique species of sea hare characterized by its distinct body shape and coloration. This sea slug features a whitish to green body adorned with brown specks and a complex network of white lines, which contribute to its name 'geographica.' The rhinophores, or head tentacles, are positioned further back compared to other species in the Aplysiidae family, almost nestled between the parapodial lobes. The parapodia, which are fleshy wing-like extensions, rise to a noticeable peak at the top of the animal. It can reach a maximum length of 170 mm. This species inhabits the Indo-West Pacific oceans, including areas off Western Australia, as well as the Mediterranean and Red Seas. Geographic Seahares are typically found in lagoons and bays, favoring sandy substrates. They are recorded at depths ranging from 6 to 7.5 meters, and most occurrences are shallower than 40 meters. As herbivores, they primarily feed on algae. Members of the order Anaspidea, to which this species belongs, are often simultaneous hermaphrodites, which means they possess both male and female reproductive organs. Encounters with this species during dives can be intriguing, as divers may observe their unique body shape and coloration against the sandy backdrop of their habitat.
