The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in motion as the fluid moves.
Mechanical vibrations of the stapes footplate at the oval window generate pressure waves in the perilymph of the cochlea's scala vestibuli. These waves travel around the cochlea's tip, through the helicotrema, and into the scala tympani before dissipating as they hit the round window. Sound-induced pressure changes in the cochlea travel down the fluid-filled tympanic and vestibular canals, which are filled with a fluid called perilymph. The membranous oval window functions similarly to a piston in a hydraulic system, pushing and pulling on the enclosed fluid.

Hey there!
Nocturnal animals are basically animals which sleep during the day and stay awake during the night. Most animals which sleep during the day live in the desert because of the extreme heat during the day.

The most unlikely characteristics of pioneer species is that they have long life cycles with slower growth and longer life spans.
<h3>What are pioneer species?</h3>
Pioneer species are the species to first colonize and adapt to a particular habitat.
Pioneer species are usually simple organisms with limited nutrient requirement and ate mainly photosynthetic.
They usually have short life spans.
Thus, the most unlikely characteristics of pioneer species is that they have long life cycles with slower growth and longer life spans.
