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?

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?

North American river otter [SEP] Conservation status
"Lontra canadensis" is listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. They have been virtually eliminated through many parts of their range, especially around heavily populated areas in the midwestern and eastern United States. Appendix II lists species that are not necessarily threatened with extinction currently, but may become so unless trade is closely controlled. The North American river otter is considered a species of least concern according to the IUCN Red List, as it is not currently declining at a rate sufficient for a threat category. By the early 1900s, North American river otter populations had declined throughout large portions of their historic range in North America.
