Based off the fact I see individuals with gray colors and a spotted pattern there are certainly harbor seals in this mix. I don't think I see any elephant seals in there however and I doubt those two species would congregate much together anyway
Thanks guys! I originally suspected that all of the animals were Harbour Seals but I saw some young Northern Elephant Seals today and I couldn't tell the difference between the species. At a young age there isn't a lot to differentiate between them.
