  • Why do Sea Otters have Strong Jaws and Teeth?
  • 
  • By: Ryan Hoefer
  • In the otter's environment, all of the otters have different teeth.  Some have sharp, light jaws for catching fish, some have strong, powerful jaws for crushing shells of invertebrates.  Others have powerful jaws, but some sharp teeth.
  • Teeth to crack invertebrae shells
  • Sharp teeth for catching fish
  • In the environment was a limited amount of fish, but the invertebrate population was high.  The otters with sharp teeth had trouble finding food, while the otters with strong jaws had plenty of food to eat.

  • When all of the fish were eaten and gone, the otters with sharp teeth had no more food.  The otters with strong jaws to grind shells and break them were more fit for the environment.

  • All of the otters left are fit for the environment.  They all have enough food to eat and survive.  These otters then reproduced with other otters with strong jaws.  All of the offspring the come from the otters will have strong jaws that can crack open shells.
