I remembered being taught about the 5 senses at school. I was surprised to discover that in the mean time scientists have added another 5 to the list.
- Balance and acceleration
- Temperature
- Kinesthetic sense
- Pain
- Other internal senses – a sense which is stimulated within the body
- Electroreception – able to detect electric fields (some fish, sharks and dolphins)
- Magnetoception – able to detect direction using the earth’s magnetic field (typically observed in birds – so that’s how migratory birds do it!)
- Pressure detection – within the gas bladder organ of a fish to help it regulate buoyancy
- Current detection – enables fish to navigate, hunt and hang around in schools
- Polarized light direction – an orientation ability found in bees, helping them to navigate on cloudy days
- Slit sensillae – enables a spider to detect mechanical strain in the exoskeleton, helping them to sense force and vibration
