Taxonomy

Paralomis longipes is a species of king crab described by Faxon in 1893, described by its long, elongated legs, It was known to resemble Paralomis multispina , another species of Paralomis . [4] A specimen collected by the "Albatross", which is type USNM 18536, was a large male specimen. According to Roberts, the specimen has a carapace length being measured as large as 108 mm (4.3 in) [b] and the breadth of the carapace was up to 130 mm (5.1 in). [1]

The genus name Paralomis was described by Adam White in 1856. The name is derived from the Greek prefix para- meaning "beside" or "alongside" combined with Lomis, creating a compound that literally means "beside Lomis". [5] [ improper synthesis? ] This nomenclature reflects the morphological similarity between the genus Paralomis and the related genus Lomis, which belongs to the family Lomisidae. The name "longipes" derives from Greek Latin[ which? ]: longpus meaning "long", and pes meaning "foot". [6] [ improper synthesis? ]

Ecology

The Peruvian specimens is known to be parasitized by large barnacles. [1]
