Sea Sight

Sea

A sea is a very large body of salty water. The term has two distinct meanings. The first is the interconnected body of seawater that spans most of Earth, known as the sea or the ocean. The second is a named body of water: usually either a marginal sea, or a large, nearly landlocked body of water.

Visual perception

Visual perception is the ability to detect light and use it to form an image of the surrounding environment. Photodetection without image formation is classified as light sensing. In most vertebrates, visual perception can be enabled by photopic vision or scotopic vision, with most vertebrates having both. Visual perception detects light (photons) in the visible spectrum reflected by objects in the environment or emitted by light sources. The visible range of light is defined by what is readily perceptible to humans, though the visual perception of non-humans often extends beyond the visual spectrum. The resulting perception is also known as vision, sight, or eyesight. The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science.
