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 ...
Scutes on a crocodile. Reptile skin is covered with scutes or scales which, along with many other characteristics, distinguish reptiles from animals of other classes. They are made of alpha and beta-keratin and are formed from the epidermis (contrary to fish, in which the scales are formed from the dermis).
It is theorized that these scutes are most likely modified osteoderms that evolved over time to become the protective shell that we see today. [9] The difference between scutes and scales is that scutes actually form in the lower, vascularized dermis, with the epidermal layer creating only the top surface. Scales on the other hand, form in the ...
Nine-banded armadillos generally weigh from 2.5–6.5 kg (5.5–14.3 lb), though the largest specimens can scale up to 10 kg (22 lb). They are one of the largest species of armadillos. [ 8 ] Head and body length is 38–58 cm (15–23 in), which combines with the 26–53 cm (10–21 in) tail, for a total length of 64–107 cm (25–42 in).
A video, taken by Crombie’s friend, shows the precise moment thousands of starlings fleetingly appear as one, a curved, winged form reflected in the water below. A flurry of camera shutter ...
Those sacrifices included participating in an adult film and at times collaborating with tabloid media on stories about her life, she says, to help make ends meet. "It wasn't until they were maybe ...
The articulations with neighboring scutes are located on the ventral side, and the dorsal surface is strongly sculptured while the ventral surface of wings is smooth and contains many small openings. "The scutes have very wide wings and cover practically the whole upper part of the trunk. The tail scutes are narrower, the last of which lack wings.
