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 ...
A bite is defined as coming from the mouthparts of the arthropod. The bite consists of both the bite wound and the saliva. The saliva of the arthropod may contain anticoagulants, as in insects and arachnids which feed from blood. Feeding bites may also contain anaesthetic, to prevent the bite from being felt.
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.
Dog bites are commonplace, with children the most commonly bitten and the face and scalp the most common target. [14] About 4.7 million dog bites are reported annually in the United States. [15] The US estimated annual count of animal bites is 250,000 human bites, 1 to 2 million dog bites, 400,000 cat bites, and 45,000 bites from snakes.
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]
A dog in West Virginia is thriving after a suspected snake bite which left him with an extremely swollen head.. The story of the dog's plight recently went viral following a Reddit mention, but ...
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.
The EFSA summarized that the killing methods most likely to cause pain and distress are: [85] Any procedures whereby the abdomen is separated from the thorax; The removal of tissue, flesh, or limbs while the crustacean is alive and fully conscious; Placing crustaceans in water slowly heated to the boiling point
