In the center of the carapace are five vertebral scutes and out from these are four pairs of costal scutes. Around the edge of the shell are 12 pairs of marginal scutes. All these scutes are aligned so that for the most part the sutures between the bones are in the middle of the scutes above.
Dermal scutes are also found in the feet of birds and tails of some mammals, and are believed to be the primitive form of dermal armour in reptiles. The term is also used to describe the heavy armour of the armadillo and the extinct Glyptodon , and is occasionally used as an alternative to scales in describing snakes or certain fishes, such as ...
The plastron features paired gular, humeral, pectoral, abdominal, femoral, and anal scutes. [8] The shell serves as external armor, although loggerhead sea turtles cannot retract their heads or flippers into their shells. [22] Sexual dimorphism of the loggerhead sea turtle is only apparent in adults. Adult males have longer tails and claws than ...

Whether listening to a popular song, watching a television show, seeing a film or reading a magazine, the totality of human sexual pleasure is often reduced to a penis penetrating a vagina.
These varied structures should be thought of as anatomical analogues, not homologues, and do not necessarily indicate monophyly. The structures are however derived from scutes, common to all classes of amniotes and are an example of what has been termed deep homology. [3] In many cases, osteoderms may function as defensive armor.
We’re only a few hours into 2025, but golf doesn’t take a holiday. Or not much of one, at least. Barely a month after the end of the 2024 fall season, the PGA Tour’s 2025 slate kicks off in ...
The epidermal scutes of the alligator consists of oblong horny scales, arranged in transverse rows; the long axes of the scales are parallel to that of the body.On the tail, except along the mid-dorsal line, and on the ventral side of the trunk and head these scales are very regular in outline and arrangement; on the sides of the head and trunk and on the legs they are much smaller and less ...
