    1. Common name: Sea Otter 
    2. Location and Habitat 
    •  Can be found living in lakes, wetlands, marine coasts, streams, etc.
    • Live in the Northern American Coast 
    •  The only specific requirement is good water quality and food supply for the Otter                                                                       
    3. Physical characteristics (internal & external)
    • Otter's anatomy allows Otters to be able to live both on kand and in the water 
    • They have slim and long bodies made up of short limbs with webbed paws which allow the otter to move easily and keep balance
    • They have very long tails which allow them to move and steer through the water
    • They have very strong senses of smell, eyesight, and hearing, with additional whiskers that further help their senses 
    4. Behavior Characteristic
    • Spend majority of time in the water and gathering food
    • They are commonly seen carrying rocks because they use to rocks to break apart food which is very unique to the Sea Otter because they are one of the only species besides primates that use tools.

This shows evolution within in family. ]]> 2017-06-05 23:19:43 UTC https://padlet.com/mary_bruning/wcgkvzeeh1dv/wish/175295178 Anatomy evidence mary_bruning https://padlet.com/mary_bruning/wcgkvzeeh1dv/wish/175295242
  • All Mustelids have scent glands which can produce repellent smells and help distinguish the different species 
  •  They all have similar body types, being long, small, and short legs
    • This shows the common the anatomy shared by all the species in the Mustelidae family, showing evolution.

     - The embryo stays in mommy until after hibernation

    Type of evolution- Divergent

    • Isolation and random and non random mating plays a role in the evolution of the family

Descent with modification is shown in the family Mustelidae by parents passing down traits to their offspring such as behavior characteristics, physical, or DNA. 
    2. Stabilizing natural selection is shown because those with extreme phenotypes tend to struggle more than those with moderate. ]]>     2017-06-05 23:23:11 UTC https://padlet.com/mary_bruning/wcgkvzeeh1dv/wish/175295425
