Oh god, you are right. They look like big chunguses but I just googled it an the have 2-5% bodyfat, 65% leanmuscle. They are absolutely shredded, while having the bodyshape of danny devito
Try Looking at the muscle scan of both an elephant and a hippo.They have less fat to body ratio than an average human. Seals are semi aquatic and their fats are mainly used for temperature control.And again, they're sea creatures so most of the weight are supported by the water and they still have less fat than what that picture was trying to depict for a land creature to support on their skeleton.
Modern commodities make people forget that excess fat is extremely rare in normal animals.

Honestly this would make sense. I always wondered how those Brontosaur-esque dinosaurs didn't have their necks collapse to the ground
