Bear and bigcats anatomy

[parvez]

Brown bears' digestive system is similar to that of carnivores except that they have elongated intestines to compensate for digestion of vegetarian food. Like ruminants, bears do not have caecum. So, plant components are weakly digested. To compensate for inefficient digestion of cellulose, bears maximize the quality of vegetal food items ingested, typically foraging for plants in the phenological stages of highest nutrient availability and digestibility (Herrero 1985). It is thought that barrel shape of bears body is an indication of a longer intestine. Reply
