A tripartite structure is recorded from near the antennae, consisting of elevated walls arranged in a semicircle (likely to enlarge the surface for an excretory organ as in modern crustaceans), a pore representing an opening of the “antennal gland” (the purpose of which is unknown) and a sickle-shaped furrow surrounding this pore.
Coxal gland and its components. The coxal gland is a gland found in some arthropods, for collecting and excreting urine. They are found in all arachnids (with the exception of some Acari), and in other chelicerates, such as horseshoe crabs. [1] The coxal gland is thought to be homologous with the antennal gland of crustaceans.
In Crustacea, the saccate metanephridia are associated with the antennae and form the antennal gland. In freshwater crustacea , the saccate metanephridia are especially large due to their role in osmoregulation; crustacea must remove large amounts of water from the tissues, as the cells are hypertonic to the surrounding water.
Arubolana imula is a species of crustacean in the family Cirolanidae, endemic to Aruba. [1] It was described in 1979 by Lazare Botosaneanu and Jan Hendrik Stock. [ 3 ]
The Aeglidae are a family of freshwater crustaceans currently restricted to South America. They are the only anomurans to be found in fresh water except for a single hermit crab species, Clibanarius fonticola, on Espiritu Santo, Vanuatu. [1] They live between 20° S and 50° S, [2] at altitudes between 320 and 3,500 m (1,050–11,480 ft). [3]
Virgin Australia crew members were allegedly sexually assaulted and robbed in one of Fiji's nightclub areas on New Year's Day, the island country's Deputy Prime Minister Viliame Gavoka announced.
The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. [10] The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. [11]
