Facts: Bullock's Hypselodoris

Bolux ipsilodorus is a small dored nudibranch that inhabits the tropical Indo-Pacific. Nudibranchs are sea slugs that do not have an internal or external shell. They use their muscular foot to crawl along the seafloor. Bolux ipsilodorus nudibranchs have a high body profile. Their color varies from white to pink to purple, with a distinct white margin. They are very smooth, giving them a polished look. There are other species that look very similar. They have a pair of sensory organs on their head called rhinophores. The rhinophores serve to pick up smells in their environment. Feathery external gills are located on their back. The feathery gills maximize surface area in order to extract oxygen from the water. The rhinophores and gills are orange or yellow, with a purplish base. They live on coral reefs at depths of 33 to 66 ft. They are considered uncommon. They feed on sponges. They have simple eyes that are only able to discern between light and dark. Nudibranchs are simultaneous hermaphrodites. This means that they have both male and female reproductive organs. They can mate with any other mature member of their species. Bolux ipsilodorus nudibranchs lay yellow, spirally-coiled egg ribbons. Eggs hatch into planktonic larvae that eventually become bottom-dwelling adults. For more marine facts, click the SUBSCRIBE button!!
