Harbor Seal Pups in Puget Sound – NOAA Study

This great YouTube video talks about harbor seal populations in Puget Sound through the narration of Harriet Huber, a NOAA researcher. Harbor seals were once seen as competitors to Puget Sound fisherman and had no legal protection. They were widely killed and their populations decreased almost to the point of extinction.

Harriet and NOAA has been monitoring harbor seal populations since 1993 and has watched their population increase and level off to what is known as the carrying capacity – the steady state population of a predator that an ecosystem can support.

Some interesting facts I learned from watching this YouTube video is that female harbor seals can have pups up to age 25 and males can live as long as 20 years. I thought it was really interesting how much longer the females can live and reproduce compared to the males.
