Differences Between Marine and River Dolphins
Both river dolphins and marine dolphins belong to a group of mammals called cetaceans, but they differ somewhat in appearance. For example, the snout of a river dolphin measures about 58 centimeters (2 ft) long, approximately four times as long as that of most marine dolphins. River dolphins have smaller eyes than marine dolphins, and their vision is poorly developed because they live in dark, muddy water. This environment also makes river dolphins less active than marine dolphins. River dolphins feed primarily on fish.

“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts.

Of each of the senses; call it, again and again,
The river that flows nowhere, like a sea.”

gray sea-smoke
Into pale sea, look west at the hill of water: it is half the
planet: this dome, this half-globe, this bulging
Eyeball of water,”
