What the species is and where it came from
The great white shark is the sole extant species of Carcharodon, a lamniform shark native to tropical and temperate oceans worldwide. It is not endemic to any single sea or coast.
How it works, in terms someone would actually use
It swims vast distances across oceans, moving between coasts and open water, even crossing continents. Its liver holds over a quarter of its body weight to float and fuel long journeys. Its 300 serrated teeth cut through seals, dolphins, squid, fish and other sharks. Regional endothermy lets it hunt in cold water where prey is abundant.
What it gets right
It gets migration right: it travels between coasts and open ocean, across continents. It gets thermal strategy right: partial warm-bloodedness enables cold-water activity. It gets feeding ecology right: marine mammals are confirmed prey, not speculation.
What it does not
It does not stay in one place. It does not rely solely on sight or smell—it uses multiple senses, but the document says nothing about how. It does not dominate all ocean zones: it avoids polar waters and is regionally critical in European and Mediterranean waters.
What it changed
It changed how we understand shark physiology: regional endothermy, massive energy-storing livers and continuous tooth replacement are now benchmarks for predatory adaptation in elasmobranchs.
Who it is for, and who it is not
It is for marine biologists tracking migrations, conservationists assessing IUCN Vulnerable status, and coastal observers in North America, southern Africa or Oceania. It is not for freshwater divers, Arctic researchers, or anyone expecting static behaviour or localised residency.
Is it worth your time
Yes—if you are near temperate or tropical coastlines in North America, southern Africa or Oceania, and want to witness a highly migratory apex predator that reshapes marine food webs by direct predation on marine mammals.
