According to the docents last time she was weighed she was a whopping 415 ibs. I say last time because they can’t fit her on to the scale anymore. The normal size of Reticulate Whiptail Rays is 260.
@Westcoastperson Yeah she's pretty stunning. I'd actually seen the species once before at Cal Academy of Sciences, but I didn't realize it until later because that aquarium's ray is much smaller!
