A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
The researchers who studied E. omoensis found that its tooth enamel δ18O values had a standard deviation of 2.7%, falling outside the δ18O standard deviations of the sea otter, and the North American river otter (Lontra canadensis), which were recorded to be 0.6% and 0.3%-0.9% respectively.
Mother otters have one pup at a time and sea otter pups are dependent on their mothers for an average of 6 to 7 months. Extremely young pups cannot swim or dive due to their natal fur coating, so they must be anchored to the mothers at all times. Otter pups therefore receive undivided attention from their mothers for prolonged periods of time.
They are found on all continents except Antarctica and Australia, and are a diverse family; sizes range, including tails, from the widespread 17 cm (7 in) least weasel to the 1.8-meter (6 ft) giant otter of Amazonian South America. Habitats vary widely as well, from the arboreal marten to the fossorial European badger to the marine sea otter.
