LookingatTextComplexity

R 2.9 Animals make vibrations in thewater when they move. Sharks canfeel these vibrations. Sharks use thissense to find animals that are hurtand struggling in the water.

R 6.7 Shark scales are not likeordinary fish scales, they are muchsmaller and are more like teeth whichrise up from the shark’s skin. Thescales, called dermal denticleswhich literally means ‘tiny skin teeth’,all lie in the same direction, from headto tail (so if you ever dare to get closeenough to a shark to stroke it, it willbe smooth in one direction and roughlike sand paper in the other).

R 10.3 Among the most ancient andprimitive sharks is Cladoselache, fromabout 370 million years ago, whichhas been found within Paleozoic stratain Ohio, Kentucky and Tennessee. Atthat point in Earth's history these rocksmade up the soft bottom sediments ofa large, shallow ocean, whichstretched across much of NorthAmerica. Cladoselache was onlyabout 1 metre (3.3 ft) long with stifftriangular fins and slender jaws. Itsteeth had several pointed cusps,which wore down from use. From thesmall number of teeth found together,it is most likely that Cladoselache didnot replace its teeth as regularly asmodern sharks. Its caudal fins had asimilar shape to the great white sharksand the pelagic shortfin and longfinmakos. The presence of whole fisharranged tail-first in their stomachssuggest that they were fast swimmerswith great agility.
