From Wikipedia, the free encyclopedia
Aplysia gigantea is a species of sea slug, a shell-less marine gastropod mollusk in the family Aplysiidae. The species was first described in the Journal of the malacological Society of Australia in 1869. [1]A. gigantea is also known more commonly as the sea hare due to their posterior chemosensory tentacles resembling a hare's ear.[2] A. gigantea is the largest known species in Australia of the opisthobranch genus. [3] The species is known to have toxic effects on terrestrial organisms, particularly domestic dogs.[4] Exposure to this species with dogs has been associated with the development of neurotoxicosis, with symptoms ranging from respiratory distress to tremors, muscle fasciculations, and seizures. [4]
Aplysia gigantea are commonly found near the southwestern corner of Western Australia, in soft sediment or reef.[2] They are found in shallow water, ranging from 0-20m in depth.[2] A. gigantea are most commonly witnessed from January to March and it is not uncommon to witness beach strandings of this species numbering in the hundreds. [3] A. gigantea are found most often in waters that range from 13.1-23.2°C. [2] The species has not yet been assessed by the IUCN, and thus its conservation status remains unknown.[1]
A. gigantea are known to be able to grow up to 60cm long, making it one of the largest species of sea hare in Australia.[2] They are usually a dark brown or black color. Additionally, they are distinguished by large paradopia on their backs, which function as limbs allowing for swimming for short periods of time. [2] The species also has scent and taste receptors known as rhinophores, located on the dorsal surface of its head. [4] These organs resemble a hare's ears and are responsible for it's more colloquial name of sea hare. The sea hare's eyes are also located beneath the rhinosphores, and are able to sense light and shadow. [3] The organism's gills, as well as an internal, calcified shell is also present, and are located in close proximity to the its heart. [4] The shell itself is particularly fragile, and the paradopia serve a secondary function in both enclosing and protecting it. [4] The adults of this species are also herbivorous in nature, with a diet that primarily consists of algae. [1]
A. gigantea is able to produce inks and secretions from two main secretory glands that render hidden or toxic to predators. [5] When ingested by domestic dogs, several symptoms have been recorded, including respiratory issues, ptyalism, emesis, ataxia, and hyperaesthesia. [4] It is suggested that the sea hares' diet of red algae provides the molecules needed to create toxins. [2]
A. gigantea mate during summer and early autumn.[2] A. gigantea are hermaphrodites and often mate in numbers ranging from 2 to around 20, and produce orange colored spawn. [2] In these mating groups, one individual will utilize only female or male reproductive organs respectively, while other participants use both. [2]The eggs produced by A. gigantea are in long and stringy clumps, and hatch into planktonic larvae which feed on microscopic algae. [3]
