where do river otters live in the winter They travel drastically less during winter. is this creature a mammal, reptile, amphibian, or any other? Mammal how long can this creature live underwater? 4 minutes do they have a special respiratory system or any other metabolic adaptations to survive underwater for so long? The right lung of the North American river otter is larger than the left, having four lobes compared with two for the left. Reduced lobulation of the lungs is presumed to be adaptive for underwater swimming. In addition, the length of the trachea of the North American river otter is intermediate between that of terrestrial carnivores and marine mammals. The mean tracheal length of the North American river otter is , or 23.2% of the body length. A shorter trachea may improve air exchange and increase lung ventilation in diving mammals. how do they communicate? Communication among them is accomplished mainly by olfactory and auditory signals. Scent marking is imperative for intergroup communication. at what age do females start reproducing? Females usually do not reproduce until two years of age. how many pups do they give birth to? Litter size can reach five, but usually ranges from one to three. what is their gestation period? 61–63 days. what do these animals eat?

American alligator [SEP] Eggs
The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. When the young begin to hatch — their "yelping" calls can sometimes even be heard just before hatching commences — the mother quickly digs them out and carries them to the water in her mouth, as some other crocodilian species are known to do.
