| Have mouth salivary glands? | No Have very small salivary glands, and do not contain digestive enzymes. |

| Length of intestinal track Used for passing through food.SIL: Small Intestines Length BL: their Body Length |
SIL= 3 x BL |
SIL= (10-12) x BL
Need
1. dietary fiber to move food through.
2. longer SIL for efficient nutrient absorption. |
