There are two major body types. One is characterized by stocky bodies, short legs, and a large head. The other is characterized by a slender build and long legs. Hippos and bison are part of the first group and deer are members of the second group. Another similarity in structure is they all have an even number of toes. White tailed deer and american bison have two toes on each foot and hippos have four toes on each foot. ]]> 2017-05-30 15:27:03 UTC https://padlet.com/lj987/rbaovlu5cri8/wish/174438928 lj987 https://padlet.com/lj987/rbaovlu5cri8/wish/174644865 The white tailed deer, hippo, american bison are pregnant for between 6 to 9 months.
