In the first picture is possible to spot (arrows), thanks to the transparency of the holothurian skin (sea cucumber), two specimens of the tanaid - small, bottom-dwelling marine crustaceans, living inside the holothurian. Here they use their claws to feed on the host skin. In some cases the parasites excavated ‘tunnels’, (picture on the right).
