Kingdom Hearts II Sora-dolphin or shark?

Ok, so I'm staring at the picture of Sora as a merboy, and I'm thinking, what the heck is his half? A dolphin, or a shark?
Right now, in this thread, we've written him mostly as a shark, but with many opinions. Heres some:
Hes a dolphin!
Cause of Dolphin kick
Soras not tough
Soras too sweet
The way the fin looks like
Hes a shark!
Humans can do dolphin kick
Looks like a shark

 

He has a "Dolphin Kick" (or something like that) in KH2, which pretty much confirms that he's a dolphin.

 

Well, I thought it looked more like a shark, but my sis, who's somewhat of an animal expert, says it's a dolphin.

 

Heh, silly question... But I think it's a Dolphin... even though it looks very much like a shark.

 

Dolphins have Dolphin Kicks. Sharks would have... Shark Kicks?

So therefore, I think he's a dolphin.

 

sharks or well most of them have vertical tails the dolphin has a horizontal tail thus dolphin.

 

Dolphin. Sora's too soft to even take a form of a Shark. :P

 

dolphin defenatly, there is no way it can be a shark could it?

 

Dolphin...because of "dolphin kick" in KHII...

 

All of them do have vertical tail. So It is dolphin as you said

 

Well, I think the part with the tailfin is said by alot of members here. But look at the way he swims. Sora swims exactly like a dolphin does.

 

ok. first of all. Humans can do "Dolphin Kicks" and not be Dolphins. :|. Second. I think he is half dolphin becuz of the way he swims. Sharks dont really do the whole tale splashing about and what-not.

 

Sora's a dolphin, if he was a shark, if he ever stood still, he would start drowing. That what's funny about sharks, if they stop moving, they drown. XD

 

I suppose that might be the reason they made him part dolphin... lol

 

Sora is such a pushie.
Of course he's a dolphin :3 ​

​

 

and the tail reminds me more of a dolphin then a shark

 

He's a dolphin. The way he swim is the same way a dolphin do.

 

It's totally a shark.

 

Sora's a dolphin because of the way he swims. And because he's not very....erm...tough.

I bet if they had their way making the game he could have been a jellyfish or something. That would have been funny.
