Common name: Ercolania boodleae

General information

Ercolania boodleae is a species of sacoglossan sea slug, a small, often overlooked invertebrate that dwells in marine environments. These creatures are known for their unique ability to incorporate chloroplasts from the algae they consume into their own tissues, a process known as kleptoplasty. This allows them to utilize photosynthesis, much like plants, to supplement their diet with energy from sunlight.

Care

Ercolania boodleae requires a specialized environment that mimics their natural habitat. They thrive in tanks with plenty of live macroalgae, which serves as both a food source and habitat. Stable water conditions and a mature tank with established algae growth are crucial for their survival. They are sensitive to fluctuations in water quality, so regular monitoring and maintenance are essential.

Reproduction

These sea slugs are hermaphrodites, possessing both male and female reproductive organs. They can reproduce through cross-fertilization, which increases genetic diversity. In captivity, if conditions are favorable, they may lay egg masses on the surfaces of algae, where the larvae will develop and eventually settle as miniature adults.

Symbiosis

The most fascinating aspect of Ercolania boodleae is their symbiotic relationship with algae. By retaining chloroplasts from the algae they eat, they can perform photosynthesis. This not only provides them with additional energy but also contributes to the health of the aquarium by potentially reducing excess nutrients.

Habitat

Ercolania boodleae is typically found in shallow, sunlit waters where there is an abundance of their preferred food source, the green algae of the genus Caulerpa. They are adept at blending into their surroundings, making them a challenge to spot in both their natural environment and in home aquariums.
