AR-S07 / RESEARCH FILE
This record pertains to the observation and examination of individual "AR-S07," currently held in the AQUA RISE Research Wing. Records regarding physical characteristics, behavior, and body structure are ongoing, but at this point, there are very few elements that fit existing biological classifications. In particular, the internal structure shows abnormalities that do not match any marine organism confirmed to date.
