they cant poke, to get the attention of another dolphin the nudge them with the tip of their nose or swim by them "talking"or simply hit them with a fin
The bottle nose dolphin is what most american's consider the look of dolphins. These are the ones you see in movies and usually swim alongside. To give you their looks, they have a sharks fin on top, and swimming find on both sides. They have a beak that protrudes out and is lined with small sharp teeth, although they are only used for fighting and other activities. The eyes are on both sides of their heads about an inch and a half from the curves of their mouths. and their blow hole is located just above their Mellon.
