This species was first described in 1988 from a few specimens originally found in Paise food market. To date, there are perhaps no more than 350 C. mccordi known to exist, all of which came out of the food markets and now are in private or zoo collections, many of which are in Japan. Despite this grim outlook, survival prospects for C. mccordi, in particular, are promising. C. mccordi adapts well to captivity and is consistently reproducing.
