Can dolphins and puffer fish cross?

Dolphins: Vertebrates, Chordata, Mammals, Whales, Toothed Whales, Dolphins.

Pufferfish: vertebrates, chordates, fishes, bony fishes, fugu, Tetriginae, Tetriginae.

From the above points of view, puffer fish are animals of the same class, and hybridization needs to belong to the same family. If it is not the same, it will often fail. Liger's hybridization success rate is very low, and it is impossible to succeed with such distant animals as dolphins and puffer fish.
