context_page_description: Nemanthus annamensis, commonly known as the gorgonian wrapper, is a species of sea anemone found in central Indo-Pacific waters.
context_section_description: Nemanthus annamensis has been found living in association with the crab Lauridromia intermedia. Crabs in the family Dromiidae are often known as "sponge crabs" due to their habit of carrying bits of sponge, and occasionally other objects, on their carapace. In this instance, the crab was carrying a specimen of Nemanthus annamensis, holding it in place with cheliped-like structures on the end of its fourth and fifth pairs of legs. The sea anemone was not attached to the crab's shell and seemed to be happy with being carried around as it extended its tentacles in a normal manner. It would seem that the crab uses the anemone as camouflage or takes advantage of the anemone's nematocysts as a defence against predators.
  Nemanthus annamensis is a host of the parasite Gastroecus caulleryi, a copepod.
