The eastern rock lobster is the largest species of lobster in the world, reaching up to 7 kg when fully grown. Few if any individuals reach this size, however, as the species has been heavily fished for many years. The commercial catch has fallen from around 400 t/yr in the 1980s to around 150 t/yr over the last decade.

The freshwater crab genus Nanhaipotamon is endemic to southern China and Taiwan. The taxonomic state of the genus is not entirely understood, as is the distribution of the known species. Many species only exist in a small range, for example N. zhuhaiense, only known from a few hill stream in the city of Zhuhai. Nanhaipotamon guangdongense was described 1997 by Dai from an unknown site in Guangdong province. 2012, Huang et al. found specimens of N. guangdongense living sympatrically with N. zhuhaiense, the first record of the species since 1997.I found this specimen and many more hidden in deep burrows next to small hill streams between 50 and 300 m above sea level in a subtropic hill forest. Adults left their burrows only at night, stayed near the entrance but only went back when approached directly (30 cm distance). N. zhuhaiense was not found at any of the visited sites.
