Coryphellina delicata

Coryphellina delicata is an aeolid nudibranch that exhibits a delicate appearance typical of its family, Flabellinidae. This species is primarily found in the Indo-Pacific region, with recorded sightings from locations such as Madang in Papua New Guinea, Aliwal Shoals in South Africa, Indonesia, and Japan. Divers can encounter this species in shallow waters, as it has been recorded at depths shallower than 40 meters, with 90% of occurrences at depths around 30 meters or less. It typically inhabits coral reefs and other related marine environments. Feeding habits of Coryphellina delicata involve grazing on small invertebrates, which are part of its diet. The nudibranch's reproductive behavior is not detailed in the sources, but many nudibranchs are known to be hermaphroditic, possessing both male and female reproductive organs. Encounters with this species during dives can be intriguing, as divers may observe its slow-moving nature and distinctive body structure, which helps it blend into its surroundings. The conservation status of Coryphellina delicata is not evaluated in the sources, indicating that its current threat level is unknown. However, as with many marine species, habitat degradation and environmental changes could impact its populations in the future.
