Great White Sharks

They Aren't As Bad As You Think...

Food Chain

  • Great whites feed on fish (tuna, rays, sharks), cetaceans (dolphins, whales), pinnipeds (seals, sea lions), sea otters, sea turtles, and sea birds (WIKI)
  • They are carnivorous (WIKI)
  • Pods of orcas can rival great whites (WIKI)

Habitat

  • Great white sharks live in waters between the temperatures 54 degrees Fahrenheit and 75 degrees Fahrenheit (WIKI)
  • Normally can find them around rich, high fat content game (WIKI)

Description

  • They are fish contrary to popular belief (WIKI)
  • Great whites have rows of serrated teeth for chomping off pounds of meat per bite (WIKI)
  • When teeth fall out, the tooth behind it replaces it (WIKI)
  • Males are generally 11-13 feet long, females 15-16 feet long (WIKI)
  • They average 1500-2400 pounds (WIKI)
  • The biggest recorded shark is 20 feet long and 4200 pounds (WIKI)
  • They have a white belly, hence the name Great White Shark (WIKI)
  • They also have a gray dorsal area (WIKI)
  • Extremely powerful jaws that can hold up to 31 pounds of meat at a time (WIKI)

Adaptation

  • Great white sharks are able to sense electromagnetic waves (WIKI)
  • Every movement in the water creates an electromagnetic wave (WIKI)
  • They can sense half a billionth of a volt (WIKI)
  • A special adaptation allows them maintain their blood temperature higher than the surrounding waters temperature (WIKI)
  • This allows them to hunt faster (WIKI)
  • 20 foot sharks are estimated to have a bite force of at least 4000 pounds (WIKI)

Reasons For Endangerment

  • They have been hunted for since the 1970's (WIKI)
  • They are considered "vulnerable" on the endangerment scale (WIKI)
  • Great whites that are captured between the time of birth and sexual maturity never reproduce (WIKI)
  • They're targeted for their jaws, teeth, fins, and flesh (WIKI)

Critical Info

  • If sharks became extinct, it would create chaos in the food chain (WIKI)
  • Great whites rarely attack humans (WIKI)
  • Humans die more from bumblebees than sharks (WIKI)
