### animal | vertebrate | fish | ray:

Light ray
* All light rays are bent the same amount by gravity
  - coming from the light source are parallel and point in the same direction
* Most light rays fall on reflect surfaces
* Some light rays form images
  - pass through fields
  - reach surfaces
* appear to bend in the warped space surrounding massive objects.
* approaching a black hole are bent around by steeply curved space.
* are absorbed through the leaves of the plant by the plant's chlorophyll
  - bent by the cornea and the lens of the eye so that they focus on the retina
  - focused more directly on the retina and images are now more in focus
  - now focused on the retina
  - the external stimuli for vision
  - then focused on that part of the macula called the fovea
* bend as they pass from air outside the eye to the fluid within the eye.
* bounce from objects in the real world through the lens of the eye onto the retina
  - off of objects and into our eyes
* change the direction before reaching our eyes.
* come in through the lens.
* converge at principal focus of a lens
  - before they reach the retina and the brain receives a blurred image
* deflected are in the process of being altered.
* differ from one another by wavelength.
* do originate from a real image, such as the one on a movie screen.
* enter the eye through a transparent layer of tissue known as the cornea.
* enter the eye through the cornea and are later interpreted by the brain
  - cornea, the outer membrane that covers the eyeball
  - transparent tissues
* entering the eye are bent too much and are focused improperly.
* fall beyond the retina.
* focus before reaching the retina and images appear blurry
  - behind the retina, and close objects look blurred
* focus in front of the retina rather than on the retina
  - the front of the retina
* go beyond the retina, putting far objects in focus.
* pass through the cornea and then through the lens
  - throught two tubes with water flowing in opposite directions
* passing through a diverging lens are bent outward
  - curved surfaces are bent
* strike surfaces.
* travel at a fixed speed
  - in straight lines

Low beam
* are beams.
* provide better illumination in snow than high beams.

Manta
* rays as they feed on plankton bloom
  - in Malaysia
* rays, whales and dolphins are among the sea life.

### animal | vertebrate | fish | ray:

Manta ray
* are active swimmers adapted for a cruising lifestyle
  - elasmobranchs, cartilaginous fish that are almost entirely flexible
  - large rays belonging to the genus Manta
  - marine animals whose life passes quietly in salt water
  - numerous from spring to summer and during the beginning of autumn
  - planktivores and cruise the open water filter feeding out small animals
  - quiet and peaceful beings that pose no danger to humans
  - subject to other anthropogenic threats
  - the largest rays and are closely related to sharks
* eat tiny marine organisms including microscopic plankton, small fish and crustaceans.
* feed close to the surface, where plankton tends to accumulate
  - on plankton
* give birth to live young called pups.
* lack the stingray's intimidating tail spine.
* reproduce by ovoviviparity with the birth of one pup during a breeding season.
* rises from the sand at the base of a Carolina reef.
* show no territorial behavior.

Medullary ray
* are as prominent as in a dicotyl.
* connect the cental pith to the cambium.

Red ray
* decompose the salt crystals in the body and act as a catalyst for ionization.
* produce heat which vitalizes and energizes the physical body.

Sawfish
* are certainly among the most unusual of fishes
  - software
* range in color from light grey, to beige, to brown, and even olive green.
* use their saws to root out and impale their fish prey.
