Common name: Starry Nudibranch

General information

The Starry Nudibranch, scientifically known as Doriprismatica stellata, is a striking sea slug that captivates the attention of marine enthusiasts and reefkeepers alike. This species is known for its beautiful star-like patterns on its dorsal surface, which can vary in color from yellow to orange, often with a sprinkling of black spots. The frilly edges of its mantle are not just for show; they contain the nudibranch's gills.

Nudibranchs are part of the phylum Mollusca, and they are renowned for their extraordinary diversity and vibrant colors. They are also known for their ability to absorb toxins and stinging cells from their prey, which they can then use as a defense mechanism against predators.

Care

Caring for Doriprismatica stellata in a home aquarium requires attention to water quality and diet. They are sensitive to high levels of nitrates and phosphates, so maintaining pristine water conditions is crucial. They are specialized feeders, often preying on sponges, so providing a diet that mimics their natural food sources is essential for their survival in captivity.

Reproduction

Like many nudibranchs, Doriprismatica stellata 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

Starry Nudibranchs are typically found in the Indo-Pacific region, often in coral reef ecosystems where their preferred food sources, sponges, are abundant. They can be found at various depths, usually on hard substrates where they can easily forage for food.
