Hi Gary,

I have seen 3 species of turtles in Juanita Bay:

1. red-eared slider (Trachemys scripta elegans)
2. painted turtle (Chrysemys picta)
3. spiny softshell turtle (Apalone spinifera)

All 3 are introduced pets, long living but likely non-breeding.

1. Common, invasive, older specimens can be completely black. I've seen them as late as 12/24, rather cold tolerant
2. Less frequently seen, mostly spring
3. At least 2 huge specimens, seen in late spring, 2 years in a row

Have pictures to illustrate. All 3 species are reasonably easy to tell apart.
2. Is native to WA, but I think the JBP are released pets.

Stan
