Porpoise

The vaquita is a porpoise species endemic to Mexico, living in the northern end of the Gulf of California, and is considered to be in danger of extinction.

Human and elephant, mouse and porpoise, all have three small bones in their middle ear — the hammer, the anvil, and the stirrup.

They captured 25 porpoises and set them free back into the Yangtze after raising them for a month in Puqi County, Hubei.

Urging them to join me, I raced in circles through the surging water, chased my tail for the children, blew spouts of foam through the sunfilled spray, porpoised to and fro across the river in shallow leaps that stitched the air and water into a table-lace of foam.
