Black and White Spotted Sea Slug

The Black and White Spotted Sea Slug, scientifically known as Jorunna Funebris, is a captivating marine invertebrate that resides in the shallow waters of the Coral Triangle, particularly around Bali, Indonesia. This species is renowned for its distinctive appearance, featuring a soft, velvety body adorned with striking black and white spots. These vibrant patterns not only make them visually appealing but also serve as a form of camouflage against predators in their natural habitat.

In terms of behavior, Jorunna Funebris is typically found grazing on algae and detritus on the ocean floor. This species is a member of the family Agnidae and is notable for its gentle, slow-moving demeanor. As a benthic organism, it thrives in sandy and rocky substrates, where it can easily blend into its surroundings. The Black and White Spotted Sea Slug exhibits a fascinating form of locomotion, gliding gracefully across the substrate using its muscular foot, which is covered in tiny cilia that aid in movement.

The habitat of Jorunna Funebris is primarily shallow marine environments, where it can be found at depths of up to 20 meters. These slugs prefer warm waters with ample sunlight, which promotes the growth of the algae they feed on. They are often seen during the day, but may also be active at night, particularly when foraging for food. Their presence indicates a healthy marine ecosystem, making them an essential component of their environment.

Overall, the Black and White Spotted Sea Slug is not just a stunning addition to any marine display but also a reminder of the biodiversity found in the underwater realms of Bali. Their unique characteristics and gentle nature make them a favorite among marine enthusiasts and collectors alike.

To successfully care for the Black and White Spotted Sea Slug, it's crucial to maintain stable water parameters. Ideal water temperature should range between 24°C to 28°C, with a pH level of 8.1 to 8.4. While this species is not a freshwater species, it thrives in marine environments, so ensuring proper salinity levels between 30-35 ppt is essential for its health.

Feeding Jorunna Funebris requires a diet primarily of algae, detritus, and other organic matter found on the substrate. Marine algae sheets and finely chopped marine foods can be offered to ensure adequate nutrition. Compatibility with other tank mates is generally good, although it's advisable to avoid aggressive species that may harm these gentle slugs. Acclimation should be gradual; introduce them slowly to avoid shock, and monitor their behavior closely during the first few days.

Quarantine is recommended before introducing them to a main tank to prevent the spread of disease. A separate tank with stable conditions will help ensure they are healthy and free from parasites. Proper care and attention to their environment will contribute to the longevity and vibrancy of these extraordinary sea slugs.

The Black and White Spotted Sea Slug is suitable for shipping, provided that proper care is taken during the packing process. A packing density of 1-2 individuals per liter is recommended to minimize stress. They are sensitive to temperature fluctuations, so maintaining a stable temperature between 20°C to 25°C during transit is essential. This species does not have a CITES status, making export regulations more straightforward.
