Common name: Gardiner's headshield slug

General information

Philinopsis gardineri, commonly known as Gardiner's Seaslug, is a species of headshield slug found in tropical waters. This invertebrate is a member of the Aglajidae family, which is known for its unique headshield used to plow through the substrate. They are characterized by their elongated bodies, lack of a shell, and striking color patterns that often serve as camouflage or warning coloration.

Care

Gardiner's Seaslug is not a common species in the aquarium trade, but for enthusiasts who manage to acquire one, it requires a specialized environment. They thrive in tanks with a sandy substrate and plenty of live rock to explore and forage upon. Stable water quality and parameters are crucial, as with most marine invertebrates. They are sensitive to copper-based medications and sudden changes in water conditions.

Reproduction

Like many marine slugs, Philinopsis gardineri is a hermaphrodite, possessing both male and female reproductive organs. They can reproduce through internal fertilization, and they lay egg masses. In captivity, breeding is rare and not well documented.

Symbiosis

While not known for any specific symbiotic relationships, the cryptic nature of Philinopsis gardineri allows it to blend into its surroundings, which can be beneficial for maintaining the balance of microfauna in the aquarium.

Habitat

Philinopsis gardineri is typically found in the Indo-Pacific region, from the Red Sea to Hawaii, and from Japan to Australia. They inhabit sandy and muddy bottoms, often hiding during the day and becoming more active at night.
