Common name: Nembrotha yonowae

General information

Nembrotha yonowae, commonly known as Yonow's Nudibranch, is a strikingly colorful sea slug found in tropical waters. This species belongs to the family Polyceridae and is known for its vibrant green body with red or orange markings. Nudibranchs are celebrated for their diverse and often brilliant coloration, and Nembrotha yonowae is no exception, making it a fascinating subject for underwater photographers and marine enthusiasts.

Care

Yonow's Nudibranch requires a specialized aquarium setup that replicates its natural environment. They are sensitive to water quality and require stable, pristine conditions. A diet of specific sponges, tunicates, or bryozoans, which they feed on in the wild, is essential for their survival in captivity. Due to their specific dietary needs, they are considered challenging to keep and are recommended for experienced aquarists.

Reproduction

Like many nudibranchs, Nembrotha yonowae is a hermaphrodite, possessing both male and female reproductive organs. They lay spiral ribbons of eggs on the substrate or on their food source. The eggs hatch into free-swimming larvae that eventually settle and metamorphose into the adult form.

Habitat

Nembrotha yonowae is typically found in the Indo-Pacific region, particularly around the Philippines and Indonesia. They inhabit coral reefs and are often observed crawling on or near their preferred food sources. Their presence indicates a healthy reef environment with an abundance of sponges and other sessile invertebrates.
