Arctides regalis is a species of lobster found in the tropical Indo-Pacific region. It was initially thought to be the same species as A. guineensis, [2] but has since been renamed after Mary Eleanore King. [3] Its common name is royal Spanish lobster and it is known as ula-papapa in Hawaii. [1] The species is assessed as Least Concern in the IUCN Red List of Threatened Species. [4]

Description

Articdes regalis has a dark red coloration, and is covered in black bristles. [3] As part of the family Scyllaridae, Articdes regalis share the common trait of antennae in the shape of paddles. [5] Their average overall length is 17 cm. [6] Carapace length of female specimens ranges from 41 to 55 mm, while for male specimens it ranges from 40 to 49 mm. [3]

Articdes regalis often feed on snails, clams, shrimps, and crabs. [3] To open its prey, the lobster moves in dactyli in a wedging motion and extracts the body. [7] They are reported to run from divers during the day and are described as shy creatures. [3] As they become more sociable at night, they are considered to be nocturnal. [3]

Distribution & Habitat

Arctides regalis is found in the tropical Indo-Pacific region, including multiple African, Asian, and Oceanic countries. [8] It is a benthic species. [6] Due to its orange-red coloring it often blends in with Tubastraea coral that grows in its hiding place. [9] During the day, they hide in groups on the walls and ceilings of underwater caves. [3] At nights, scuba divers have reported sightings of the lobsters at depths of 5 to 50 meters in coral reefs. [6]

Human use

Aquarium trade

Arctides regalis can be kept in an aquarium with free-swimming fish, but it should be the only one of its species in the tank because they do not get along. [9] They are sought after for their vivid colors uncommon for slipper lobsters. [6]
