A mosquito

It is hard to imagine ears more different from a human's than a mosquito's. Look at a mosquito head-on, and you'll see a pair of large, wraparound eyes, and projecting from the front of its face is a pair of long, hairy antennae—its ears. Each antenna arises from a large, spheroidal base, the Johnston's organ (JO). Function follows form. Whereas human ears are pressure detectors, a mosquito's detects the particle velocity component of a sound field, which is restricted to the immediate vicinity of the sound source in acoustic near field. The mosquito's ears are insensitive to pressure fluctuations in the acoustic far field. The antenna, with its fine, interlacing network of flagellar hairs, senses movements of air particles as they are swept to and fro by impinging acoustic waves. The antenna movements excite the sensory receptors contained within the JOs to generate action potentials that flood into the insect's brain. The bottom line of functional hearing is acuity—maximize sensitivity and sharpen the tuning of each receptor cell. This tuning goes on at the level of cell and molecular biophysics—and when it comes down to fundamentals, functional similarities are often more apparent than differences, even in animals as diverse as humans and mosquitoes.

Well if its got antenna, it must be an insect. All insects use their antenna like ears and many have antenna that do more than detect sound vibrations. I still would not call them ears on their antenna.

Medium size hair because it is easy to handle and you can still perform most of the hairstyles

I've had mine both ways too... but the husband prefers it short... he never ever complains when I grow it lengthy, but is always all over themself w/the complements when I cut this off
