how long can a river otter stay under water
North American river otter Prey is captured with a quick lunge from ambush, or more rarely, after a sustained chase. River otters can remain underwater for nearly 4 minutes, swim at speeds approaching 11 km/h (6.8 mph), dive to depths nearing 20 m (22 yd), and travel up to 400 m (440 yd) while underwater. Several river otters may even cooperate while fishing. Small fish are eaten at the surface, but larger ones are taken to the shore to be consumed. Live fish are typically eaten from the head.
