What is the creature that doesn't sleep and doesn't stop movement from its birth until its death?

Question

riddle

Answer 1

a dolphin
♣

Answer 2

First I thought "insect", because of "creature".
I´m here, in Brazil, just listening to the annoying "cigarras", Cicadidae insects (Homoptera) that do not stop their noise.
But if it is a riddle, I would say a "clock":
It is created by men and if you consider "birth" and "death" as its start and its stopping... well, you know..

Answer 3

The answer should be the heart. BUT the heart is not a creature. I am coming back to this one to see the answer. I don't have a clue.

Answer 4

Even when a shark rests or sleeps, it never stops moving. If it's mouth is open too long it will suffocate, too. They are strange creatures.

Answer 5

It's Mayfly. It only lives for one day and from hatching out it flies around to find a mate. When it does it copulates then dies. The female lives long enough to lay eggs.

See below

Mayflies are classified in the Insect Order Ephemeroptera, meaning in Greek "lasting but a day." As winged adults, they survive only a few hours or at most a few days, nothing is eaten, nor do they crawl or walk. They only fly and mate within dancing swarms, usually in late afternoon or evening. Swarms, consisting of hundreds or thousands, emerge from the water after synchronously appearing along and inland of the shoreline. Mating normally occurs the same day adulthood is achieved. Females release as many as 8,000 fertile, oval eggs over the water, often scattering them or, in some species, in mass in a suitable place. After eggs are laid, females fall to the water and float, often drifting onto beaches in nuisance piles or windrows. Others are strongly attracted to and congregate under night lights.

Dead mayflies pile up, decompose and give off an offensive dead fish-like odor (stench). This material serves as a breeding ground for flies and other scavenger insects. Also, swarms can cause traffic hazards by their bodies getting crushed, resulting in dangerously slick roads and sidewalks. It is necessary for residents to shovel away mayflies near their homes, and street sweepers to clean the mess off the road. Heavy populations of swarming mayflies have been blamed for brown-outs at power plants, and even putting out campfires. Off water breezes often blow the swarms some distance inland to share the burden of windrows of mayfly bodies. Unfortunately, a reasonably large number of people, who dwell where mayflies dance and shower their debris toward earth, come down with a seasonal hay fever and sometimes serious asthma (causes sneezes and wheezes). It is believed that the protein content of insect chitin (disintegrated bodies and covering) do damage to the allergic individual's respiratory system. The presence of these nuisance insects may discourage tourism during the July 4th holiday along Lake Erie. Fortunately, the swarming season is temporarily, annoying from the last week of June through the first two weeks of July each year.

Eggs laid on the water surface gradually sink to the bottom and, after a few days or several months, hatch into tiny aquatic nymphs well adapted for living at the bottom of quiet bodies of water or rapidly flowing streams. Some species burrow into the lake sediment to feed on algae, diatoms, aquatic vegetation, other aquatic insects, etc. When mature, nymphs swim to the surface or climb up plant stems or rocks where they break the nymphal skin, wait briefly for the wings to dry, and fly off. (This subimago period lasts a few minutes to 48 hours, depending on the species.) Subimagoes are dull in appearance while true adults are shiny with longer tails and legs.
