The Sea lions were too old and couldn't get out of the pool, so they were moved to their old exhibit in the aquatics section, which will get demolished for the new Reptile House.
The exhibit remained closed for about 2 months, but then the zoo received four female harbor seals from an Aquarium in New Jersey (not sure which) while their exhibit was being refurbished, so the seals are not permanent. Now the zoo has 5 because they rescued a blind male from a beach in So. Cal. and is now doing well with the 4 females. I don't think the zoo can move the Gray seals into Sea life cliffs, mainly because 3 out of the 4 are old, and I think 2 of them are blind.
When Sea Lion Cliffs opened there was 5 sea lions, now all that is left are 2, which are an old male and his daughter.
I'm thinking that when the Seals return to NJ, that the zoo will try to acquire more sea lions and put them back in Sea Lion Cliffs with the young female, cause I'm sure the old male will probably die in a year or two.
