The Marble Shrimp, Saron marmoratus, also known as Eyespot Shrimp or Carid Shrimp, reaches a maximum length of 5 cm (2 inches). Its robust body is entirely covered in a dense layer of short, stiff setae, giving it a characteristic shaggy or mossy appearance that provides effective camouflage. The carapace and abdomen display a highly variable mottled pattern of browns, greens, reds, or greys, interspersed with irregular white or pale spots. Several prominent dark, pale-rimmed ocelli (eyespots) are often visible on the carapace and tail fan. Its rostrum is short and toothed, and its antennae are long and typically banded.
This species inhabits shallow coral reefs and rocky substrata, typically found within crevices, under rubble, and among the holdfasts of sponges or hydroids. It occurs from the intertidal zone down to approximately 20 metres (65 feet). The Marble Shrimp is omnivorous, feeding on algae, detritus, and small invertebrates. Primarily nocturnal, it remains cryptic during daylight hours, blending into its surroundings. While often observed individually, it can also form small aggregations, reflecting its social nature. Its lifespan can extend up to 5 years.
Saron marmoratus is hermaphroditic, possessing both male and female reproductive organs. This species is capable of both sexual reproduction and asexual reproduction.
