Electroreceptors are specialized sensory cells that detect electric fields, and are found in certain aquatic animals such as sharks and rays.

The retina is a light-sensitive layer at the back of the eye that contains photoreceptor cells, which convert light into electrical signals.

The cochlea is a spiral-shaped structure in the inner ear that contains hair cells, which convert sound waves into electrical signals that are transmitted to the brain.

The olfactory epithelium is a specialized tissue in the nasal cavity that contains olfactory receptor cells, which detect odor molecules and send signals to the brain.

The somatosensory cortex is a region of the brain that processes tactile information, such as touch, pressure, and temperature.

The Ponzo illusion is a visual illusion in which two lines of equal length appear to be different lengths when they are placed at different distances from a converging or diverging background.

Perception is the process by which an animal receives and interprets sensory information from its environment.

Habituation is a type of sensory adaptation in which the response to a repeated stimulus decreases over time.

The vestibular sense is a sensory system that helps animals maintain balance and orientation in space.

Thermoreceptors are specialized sensory cells that detect changes in temperature.

Proprioception is the sense of the relative position of neighboring parts of the body and strength of effort being employed in movement.

Sensitization is a type of sensory adaptation in which the response to a repeated stimulus increases over time.

Predation sense is a term used to describe the ability of an animal to use its senses to detect and locate prey.

Vestibular receptors are specialized sensory cells that detect changes in the position of the head.
