Giant otters prefer habitats with non-floodable banks that have vegetation cover and where there is easy access to hunting places in relatively shallow waters. They take a nap at mid-day during really warm weather. [13] Later gene sequencing research on the mustelids, from 2005, places the divergence of the giant otter somewhat later, between five and 11million years ago; the corresponding phylogenetic tree locates the Lontra divergence first among otter genera, and Pteronura second, although divergence ranges overlap.[21]. Long-tailed otters are more tolerant of human disturbance than Giant otters, and may inhabit degraded forest where humans are present, but they are not tolerant of pollution or substantial .
