The term mud shrimp is used for a number of different mud-dwelling crustaceans: The former infraorder Thalassinidea, which included genera such as Callianassa, Pestarella and Upogebia. Infraorder Axiidea, comprising part of the former infraorder Thalassinidea; Infraorder Gebiidea, comprising part of the former infraorder Thalassinidea
The shrimp measure up to 11 cm long in adulthood. Its snout is hairy and includes 3 teeth. They eat detritus which they bring into their burrow using their pleopods. Upogebia pugettensis is the host of many parasites: Pseudopythina rugifera, Phyllodurus abdominalis, and Orthione griffenis. [1] [2] [3]
C. subterranea creates complex, multi-branched tunnel systems up to 81 cm deep from the lower shore to the shallow sublittoral. Each tunnel complex has several inhalant shafts which terminate on the surface with a funnel -shaped opening in the center of a conical mound of ejected sediment.
Callianassa is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus (C. candida, C. tyrrhena and C. whitei) have been split off into a new genus, Pestarella, [3] while others such as Callianassa filholi have been moved to Biffarius. [4] The genus is named after the Nereid of the Greco-Roman mythology.
Upogebiidae is a family of mud shrimp crustaceans belonging to the infraorder Gebiidea, within the order Decapoda. They are infauna, living their entire adult lives in seafloor burrows. Over 100 species have been identified, with different species often highly specialized for different types of substrate, even including sea sponges or coral. [1]
