Is Jack a fishman?


In chapter 824 of One Piece, Jack is shown lying motionless on the ocean
floor, waiting for his crew to come and rescue him after being defeated by
Zunisha the giant elephant. His mask is broken and his shark-like teeth
(resembling Arlong and Hodi - the shark fishmen) is revealed. However, unlike
other devil fruit users, he does not pass out or have any difficulty breathing
in the ocean.

My question is: is Jack who happens to be a Zoan type devil fruit user also a
fishman, or is there any other possibility as to how he can survive for so
long under water?




Yes, Jack being a fishman is the only logical explanation for him surviving in
the middle of the ocean. As you noted already, he looks like a fishman too.
His devil fruit prevents him from moving but that won't stop him from
breathing (remember in Arlong park, Luffy could breathe while his body was
under water when Nojiko (Nami's sister) and Genzo got his head outside of the
pool).

It also seems it was not the first time he found himself at the bottom of the
sea as he is expecting help as if it was normal, and we can assume he either
can speak with nearby fishes or he has a vivre card on him, and is only going
to die if nobody comes to his rescue before he dies from hunger.
