[7] It is the most prominent of the genus Carpilius, due to its ability to be easily identified by the presence of eleven bright red spots located on its cream-colored carapace.

[10] Yet, these crabs are also found outside of the Indo-West Pacific region, with findings of C. maculatus reported from Hawaii to Mozambique and South Africa.

[12] The nocturnal nature of the Carpilius maculatus leads it to hunt primarily at night, with its diet consisting mainly of marine snails.

[14] The larger size of these master claws allows the C. maculatus to feed efficiently on bigger members of its prey species.

[9] Fossil records of crabs classified within the family Carpiliidae have linked it to the genera Palaeocarpilius, which was present during the middle to upper Eocene Epoch approximately 56 million years ago and found in what is now modern-day Europe, India, and Egypt.
