I’ve been up there many times and did go through my shots identifying some of them over the years. Didn’t do that with this set so far, and our guide didn’t have specific IDs. It is very fun to try and figure out “who’s who” from the catalogue of dorsal shots. There are some, like A61 “Surge” who has an unmistakable hook in the tip of his dorsal who I’ve seen quite a few times and can usually ID quickly. The males are much easier to figure out than the females in my experience, simply due to the larger, more distinct dorsals.
