Common name: Ardeadoris egretta

General information

Ardeadoris egretta, commonly known as the White Nudibranch, is a striking sea slug found in the Indo-Pacific region. It is highly appreciated by marine enthusiasts for its elegant white body adorned with yellow or orange-tipped gills and rhinophores. This species belongs to the family Chromodorididae, which is known for its colorful and ornate members.

Care

The White Nudibranch is a specialist feeder, primarily consuming sponges from the genus Halisarca. In captivity, ensuring a consistent supply of its natural diet is crucial for its survival. This nudibranch is sensitive to water quality, requiring stable conditions and excellent filtration. It is not recommended for beginner aquarists due to its specific dietary needs and sensitivity to environmental changes.

Reproduction

Like many nudibranchs, Ardeadoris egretta is a hermaphrodite, possessing both male and female reproductive organs. They can engage in reciprocal mating, where both individuals exchange sperm to fertilize their eggs. The eggs are laid in a spiral ribbon and will hatch into free-swimming larvae before settling down and metamorphosing into their adult form.

Habitat

Ardeadoris egretta is typically found in the tropical waters of the Indo-Pacific, from the Red Sea to the Western Pacific. They inhabit coral reefs and are often seen on or near their sponge prey. Divers can spot them at depths ranging from shallow waters to about 30 meters.
