Pit scales in this family have three female instars and five male instars. They are generally found on the leaves or shoots of the host plant and often cause deformation. The body is usually covered by a clear or transparent test. Eggs are laid under this and occupy the cavity formed as the adult female dies and shrinks in the autumn. Males are ...
A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. In the dorsal body cavity the brain and spinal cord are located.
Scales play an important part in the natural history of Lepidoptera. Scales enable the development of vivid or indistinct patterns which help the organism protect itself by camouflage, mimicry, and warning. Besides providing insulation, dark patterns on wings allow sunlight to be absorbed and are probably involved in thermoregulation.
Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to the shape and class of an animal.
The body is soft, with a tapering tail and loose, transparent skin. Both the body and the head are covered with scales. The teeth are small and pointed, arranged in irregular rows; the two median and single pair of basibranchial (on the most ventral gill arch) tooth patches are distinctive for this species. The eyes are tiny, deep-set, and hidden.
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
Squamata (/ s k w æ ˈ m eɪ t ə /, Latin squamatus, 'scaly, having scales') is the largest order of reptiles, comprising lizards (including snakes). With over 12,162 species , [ 3 ] it is also the second-largest order of extant (living) vertebrates , after the perciform fish .
The hagfish circulatory system also includes multiple accessory pumps throughout the body, which are considered auxiliary "hearts". [39] Hagfish are the only known vertebrates with osmoregulation isosmotic to their external environment. Their renal function remains poorly described. There is a hypothesis that they excrete ions in bile salts. [42]
