Shark
The broad category shark encompasses many different species of fish with cartilaginous skeletons. But when people use the word "shark," they usually refer to large and carnivorous apex predators. We know these sharks best for their intelligence, longevity, and sleep swimming.
Counted among the oldest vertebrates on Earth, some -- but not all -- species of shark survived mass extinction and ocean acidification. They remain relatively rare examples of fish in the warmed, acidified, cephalopod-rich oceans of the Fifth World.
#Human relations
People who live on the coast sometimes hunt sharks for their meat. Those who do will use their sharp teeth in jewelry.
#Shark People
A community specializing in relationship with sharks will invariably live on or near the sea.
Shark people know how to swim in waters with sharks, and do not fear them -- but they do respect them. They will avoid wearing shiny jewelry (which attracts sharks) while in the water and, in fact, may come to develop a cultural aversion to metal and shiny jewelry in general. They know how to dive and swim quietly and smoothly, without splashing too much.
Shark people may claim descent from native Hawaiians or Samoans, for whom sharks constitute an important part of their culture and folklore.
