The coxal gland is thought to be homologous with the antennal gland of crustaceans. The gland consists of an end sac (saccule), a long duct (labyrinth) and a terminal bladder (reservoir). [2] There is generally only one pair (two in some spiders), and they open on the coxae of the walking legs [1] or at the base of the second antennae in the ...
The saccate metanephridia are excretory glands which function similarly to the metanephridia. They are found in the arthropods: coxal glands of arachnids, antennal (or green) glands and maxillary glands of crustaceans, etc. The saccate metanephridia filter the fluid of the hemocoel, as opposed to the metanephridia which filter coelomic fluid.
Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
Isopoda is an order of crustaceans.Members of this group are called isopods and include both aquatic species, and terrestrial species such as woodlice.All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration.

An ionocyte (formerly called a chloride cell) is a mitochondrion-rich cell within ionoregulatory organs of animals, such as teleost fish gill, insect Malpighian tubules, crustacean gills, antennal glands and maxillary glands, and copepod Crusalis organs. [1]
Inflammation in these spots can cause cells to die or damage tissues or nerves, research shows. The bottom line is, dry eyes are more than just annoying. The bottom line is, dry eyes are more than ...
White spot syndrome (WSS) is a viral infection of penaeid shrimp.The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.
