One report suggests maximum areas 28m (92ft) long and 15m (49ft) wide, well-marked by scent glands, urine, and feces to signal territory. [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]. The established territory is then marked by the scent from the animals' anal glands. It is difficult to differentiate between giant male and female species as they have almost similar heads and body shapes. The peak breeding season is between late spring and early summer. In captivity, that number increases slightly to the late teens. An otter the size of a wolf lived 6.2 million years ago in what is now China.
