Much like other hermit crabs in its family (Parapaguridae), the little crustacean does not use the shells of other molluscs to shelter its vulnerable body, but rather finds a home in the soft, polypy masses built from sand and material created by sea anemones which go on to live on the backs of these crabs in an amazing symbiosis.  The new hermit crab was discovered in 2013 during a survey of the west coast of South Africa, and found restricted to a surprisingly small area for no obvious reason.

Knowing about the growing demand for eye-catching freshwater crabs from southern China, the authors took a look at the ornamental fish market to eventually identify an individual with unusually structured male gonopod, which in crustaceans is a swimming appendage modified to serve as a reproductive organ. Having their interest drawn by the peculiar crab, lead author Chao Huang managed to persuade the fish dealer to let them survey the collection site located in northern Guangdong, southern China.

Spider crabs are members of the superfamily Majoidea. Not your average-looking crab, many of them possess long thin legs (hence their name) and weird body shapes. Majoids are also known as decorator crabs because they camouflage themselves by attaching other organisms, such as seaweeds and sponges, to the spines and hairs on their legs and carapace. A search for Paranaxia specimens and data revealed a new species.
