1) I was thinking about adding a sentence to the Diet section that emphasizes why certain squids seemed to be its primary diet, (my edit is in bold):
The frilled shark eats a diet of cephalopods, smaller sharks, and bony fish; 60 percent of the diet is composed of squid varieties, such as the Chiroteuthis, the Histioteuthis, and the Onychoteuthis, the Sthenoteuthis and the Todarodes; and other sharks, as indicated by the stomach contents of a 1.6 m (5.2 ft)–long frilled shark which had swallowed a 590 g (1.30 lb) Japanese catshark (Apristurus japonicus). The high tendency to primarily consume the squids in their habitat can be supported by the frequent observation of beak remnants left behind during digestive processes.[1]

2) also in the taxonomy section I was going to add a sentence emphasizing that not only has the frilled shark lived for a many years it also has ancestry that dates back further
The frilled-shark is often associated with being a “living fossil”, as it is within a family that draws its lineage to one that lived throughout the Carboniferous period[1] From that anatomy, Garman proposed that the frilled shark was related to the cladodont sharks of the Cladoselache genus that existed during the Devonian period (419–359 mya) in the Palaeozoic era (541–251 mya). In contrast to Garman's thesis, the ichthyologist Theodore Gill and the paleontologist Edward Drinker Cope, suggested that the frilled shark's evolutionary tree indicated relation to the Hybodontiformes (hybodonts), which were the dominant species of shark during the Mesozoic era (252–66 mya); and Cope categorized the Chlamydoselachus anguineus species to the fossil genus Xenacanthus that existed from the late Devonian period to the end of the Triassic period of the Mesozoic era.

3). in the description paragraph I wanted to add more details on the jaw, and bring in comparison to other organisms:
The head of the frilled shark is broad and flat, with a short, rounded snout. The nostrils are vertical slits, separated by a flap of skin that forms the incurrent opening and the excurrent opening. The moderately large eyes are horizontal ellipsoids, which have no nictitating membrane, which is a protective, third-eyelid. Ligaments articulate the long jaws to the cranium, and the corners of the mouth have neither furrows nor folds. The jaws contain 300 trident-shaped teeth, each needle-tooth has a cusp and two cusplets; the rows of teeth are widely spaced, with 19–28 tooth rows in the upper jaw, and 21–29 tooth rows in the lower jaw. Frilled sharks are able to open jaws and devour food sources that are considerably greater than that of their size, this is a physical trait that is present in gulper eels and viperfish.[1]

4). Planned on adding a picture which greatly depicted the size and range of the jaws of the frilled shark can open.
caption: The jaws of the frilled shark are able to open very wide to engulf larger prey.

5). Adding a sentence that emphasize the habitat and location in which matting can possibly occur in frilled sharks in the Atlantic Ocean
