Sharks (superorder Selachimorpha) are a type of fish
with a full cartilaginous skeleton and a highly
streamlined body. They respire with the use of five to
seven gill slits. Sharks have a covering of dermal
denticles that protect their skin from damage and
parasites and improve fluid dynamics. They have
several sets of replaceable teeth. Sharks range in size
from the small dwarf lanternshark, Etmopterus perryi,
a deep sea species of only 17 centimetres (7 in) in
length, to the whale shark, Rhincodon typus, the
largest fish, which grows to a length of approximately
12 metres (39 ft) and which feeds only on plankton,
squid, and small fish through filter feeding.
