Abruptly every dolphin of the escort broke the surface in ecstatic leaps of unusual height, a couple walking on their tails in their joy.

A dolphin breaks a marine sponge off the sea floor and wears it over its rostrum, apparently to probe substrates for fish, possibly as a tool or simply for play.

When in December 1994 two male swimmers, Wilson Reis Pedroso and João Paulo Moreira, were harassing and possibly attempting to restrain Tião, the dolphin broke the ribs of Wilson and killed João, who was later found to be drunk.

Two big dolphins broke the surface very close to the boat.

The dolphin cannot break the net.

But no pale dolphins break the surface of the water.

The dolphins broke through, went in there, and brought me back.

At one point a dolphin broke the surface nearby, for all I know just to say hello, and nearly gave me a heart attack.
