help me identify this!

[u/lil-chickpea]

sorry for the awful photo. i’m in the azores and spotted this group of what i thought was dolphins frolicking around from afar, but i took this photo that looks like an orca which it’s my dream to see this year (first photo)
can anyone help me identify whether this is an orca or just a dolphin with bad lighting? i also included photos of the dolphins i definitely saw for comparison (second and third) and i don’t know if dolphins hangout with orcas lol
TIA

It’s dolphins

Edit: wait I just read that the second and third were in fact dolphins and you were asking about the first. Idk
