The Nudibranch Tryon's Hypselodoris Hypselodoris tryoni (ex. Risbecia tryoni) occurs in the tropical Indo-Pacific Ocean from Tanzania to the Society Islands and Indonesia to Japan and the Philippines, max. length 10cm. This species, like all the members of the order Nudibranchia, are simultaneous hermaphrodites with this mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. This specimen was encountered in the Lembeh Strait, Indonesia. 1°27'39.69 N 125°14'33.342 E at 17m depth

The Red Sea is home to a diverse array of marine life, including the striking nudibranchs, which are soft-bodied, brightly colored sea slugs. Known for their incredible array of colors and intricate patterns, nudibranchs are a favorite subject for underwater photographers and divers exploring the region’s coral reefs.Nudibranchs are gastropods, but unlike snails, they lack a protective shell. Instead, they display vibrant hues ranging from brilliant oranges, pinks, and purples to electric blues and yellows. This vivid coloration often serves as a warning to predators of their toxicity or unpalatability, though some species are harmless.In the Red Sea, nudibranchs can be found on the reefs, where they feed on sponges, algae, or other small invertebrates. Species like the Spanish dancer, known for its large size and flowing red body, and the blue dragon (Glaucus atlanticus), with its shimmering blue hues, are particularly popular with divers. These fascinating creatures are typically found in shallow waters but can also be spotted in deeper areas of the reef.The Red Sea's clear, warm waters and healthy coral ecosystems provide an ideal environment for these colorful creatures, making it a prime location for diving and snorkeling enthusiasts eager to discover the vibrant world of nudibranchs.

The Sea Slug Black Cyerce or Tiger Butterfly Seaslug Cyerce nigra occasionally occurs in the Central Pacific from the Philippines, East Indonesia and Papua New Guinea to French Polynesia on sandy slopes above 10m. The size is up to 20mm. \nThe species feeds on the calcareous green alga Udotea geppii.\nTypically the species crawls along the seafloor, but can also swim by opening and closing the cerata. When swimming, spots and stripes alternate on the exposed cerata.\nWith the cerata wide open Cyerce nigra appears to be much larger. Cyerce nigra not only needs this to swim, but probably also as a warning. Suddenly the animal appears to be almost twice as big. \nWarning is important with Sea Slugs because they are not good at escaping. \nTheir dramatic colouration, known as aposematism, is a warning: unpalatability and toxicity - both prey and predator get to live longer. \nLembeh Strait, Indonesia \n1°27'34.836 N 125°13'17.046 E at 9m depth by night
