Roman rectangular scutums of later eras were smaller than Republican oval scutums and often varied in length from approximately 37 to 42 in (94 to 107 cm) tall (approximately 3 to 3.5 Roman feet, covering the shoulder to top of knee), and 24 to 33 in (61 to 84 cm) wide (approximately 2 to 2.7 Roman feet).
Scutes on an alligator foot. A scute (/ s k j uː t / ⓘ) or scutum (Latin: scutum; plural: scuta "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds.
They are distinguished from the Argasidae by the presence of a scutum. [2] In both the nymph and the adult, a prominent gnathosoma (or capitulum, mouth and feeding parts) projects forward from the animal's body; in the Argasidae, conversely, the gnathosoma is concealed beneath the body.
The spider's body is divided into two main parts: a round cephalothorax and a larger, wider, and heart-shaped abdomen. [12] The male has a cephalothorax that typically measures 1.3 mm (0.051 in) in length and 1.25 mm (0.049 in) in width. The carapace, the hard upper part of the cephalothorax, is dark brown with black rings around the spider's eyes.
The ecdysial suture is longitudinally placed on the vertex, separating the epicranial halves of the head to the left and right sides. Depending on the insect, the suture may come in different shapes: like either a Y, U or V. Those diverging lines that make up the ecdysial suture are called the frontal or frontogenal sutures.
Body shape has effects on body posture [29] and gait, and has a major role in physical attraction. This is because a body's shape implies an individual's hormone levels during puberty, which implies fertility, and it also indicates current levels of sex hormones. [1] A pleasing shape also implies good health and fitness of the body. Posture ...
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. [1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , which includes histology (the study of the organization of tissues), [ 1 ] and cytology ...
Officially, the name scutoid was coined because of its resemblance to the shape of the scutum and scutellum in some insects, such as beetles in the subfamily Cetoniinae. [1] Unofficially, Clara Grima has stated that while working on the project, the shape was temporarily called an Escu-toid as a joke after the biology group leader Luis M. Escudero.
