5 Nudibranchs are benthic animals, found crawling over the substrate. The only exceptions to this are the neustonic Glaucus nudibranchs, which float upside down just under the ocean's surface, and the pelagic nudibranch Cephalopyge trematoides, which swims in the water column (Wikipedia). Nudibranchs are hermaphroditic, thus have a set of reproductive organs for both sexes, but they cannot fertilize themselves. Nudibranchs typically deposit their eggs within a gelatinous spiral (Wikipedia). More than 300 Nudibranch and Sea Slug species were recorded in the seas around the United Arab Emirates, and this includes the Arabian Gulf and the Gulf of Oman. In this scientific article, several species will be mentioned.
