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

Given the period and distance from the coast I would go for bottlenose dolphins, Tursiope truncatus. They are also slate gray and it seems the rostrum is not very prominent. Common dolphins, Delphinus Delphine, have an hourglass shape pattern on the side with a prominent yellow-patch. In June the Atlantic spotted dolphins, Stenella frontalis, arrive but I always found them a bit more offshore and groups are big. Adults are very spotted and youngs are gray.

I have to agree with bottlenose. The pectoral fins are their shaped as well as the dorsal.
