we just got two in where i work. they are the most agressive mammals in the ocean and i've been in the water with them for the past 4 days. they both have brain parasites and one of them got an MRI and they found a brain abscess. unfortunately, they only have 25% chance of surviving. but the good news is that they have been swimming on their own for the most part and today they finally ate on their own. hopefully they keep improving though!
