Until now, the semi-terrestically freshwater crab Nanhaipotamon hongkongense was due to lack of better distribution knowledge considered a Hong Kong endemic. During a night walk in Shenzhen, however, I found crabs resembling the phenotype of N. hongkongense, so this species is most probably distributed in the southern parts of Guangdong, as well. Other than N. guangdongense, which was abundant and not too hard to observe at some sites in Zhuhai, I was not able to find a site where N. hongkongense was similarly abundant. The crabs tend to flee and hide in their burrows at the slightest disturbance and may therefore be more cryptic than allied species in southern China. Of all Nanhaipotamon species, N. hongkongense is the most traded in pet markets even in Europe because of its variable and signalling red or orange colour and vivid behaviour.Collections of wild animals may pose a threat to current populations in Hong Kong. This and a cryptic life history may be the reason why they did not seem to be as abundant as N. guangdongense.Wutong Shan, Shenzhen, China.

I caught a snapper off the rocks on Rangitoto Island and when I had landed it, this creature crawled out of it's mouth. I happened to have my camera with me - I was nearly gagging watching it.Cymothoa exigua, or the tongue-eating louse, is a parasitic crustacean of the family Cymothoidae. It tends to be 3 to 4 centimetres (1.2 to 1.6 in) long. This parasite enters through the gills, and then attaches itself at the base of the spotted rose snapper's (Lutjanus guttatus) tongue. It extracts blood through the claws on its front, causing the tongue to atrophy from lack of blood. The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish. Once C. exigua replaces the tongue, some feed on the host's blood and many others feed on fish mucus. This is the only known case of a parasite functionally replacing a host organ. It is currently believed that C. exigua are not harmful to humans unless picked up alive, in which case they can bite.Imagine if Cockroaches crawled into your mouth at night and attached itself to your tongue.
