### animal | vertebrate | fish | ray | stingray:

Freshwater stingray
* are hard to see, because they often bury themselves in river sediments
  - very dangerous
* can have up to three venomous spines in their tails.

River stingray
* Most river stingrays eat fish
  - small fish
* Most river stingrays have mouths
  - small mouths

### animal | vertebrate | fish | ray | stingray:

Southern stingray
* Most southern stingrays have senses
  - strong senses
  - teeth
* Some southern stingrays have disks
  - tops
  - whips
* are preyed upon by sharks and other fishes
  - related to sharks and skates
  - the largest stingray found along southeastern U.S. shores
* eat bivalves, worms, small fish and crustaceans.
* have a venomous spine on the upper side of their tail
  - extremely strong senses
  - flat, diamond-shaped bodies with indistinct heads
  - large, flat, diamond-shaped disks without distinct heads
  - white underbellies and slate gray, brown, or black upper surfaces

Torpedo
* are alarm
  - armaments
  - fireworks
  - weapons
* have homing devices that follow the target and guide the torpedo to it.
* is the smalles suborbital fitting goggle in the world.

Ultraviolet ray
* Most ultraviolet rays penetrate atmospheres.
* Some ultraviolet rays affect plants.
* Some ultraviolet rays cause cancer
  - skin cancer
  - penetrate skin
  - reach surfaces

### animal | vertebrate | fish | ray:

X ray
* are at the short end of the light-wave spectrum
  - electromagnetic radiation
  - high energy light waves
  - ionizing radiation
  - located in airports
  - one of the most useful forms of energy
  - photons that usually originate from energy transitions of the electrons of an atom
  - preferred because they resolve molecular structure
* can compliment surgery and medical oncology
  - help identify many causes of joint pain, such as a fracture or arthritis
  - penetrate most structures
  - produce biological, chemical, and physical changes in the substances they enter
* come from energized gas.
* have higher energy than radio waves
  - frequency than radio waves
  - longer wavelengths than gamma rays and shorter wavelengths than ultraviolet rays
  - shorter wavelengths than radio waves
  - the same characteristics as gamma ways, but they are produced differently
* heat the outer surface of the capsule, for an instant, to about a million degrees.
* illuminate dynamics on near-atomic length scales.
* interact with the electron cloud surrounding the nucleus of an atom.
* kill cancer cells more readily than they kill normal cells.
* knock electrons out of their orbits around an atom's nucleus, creating charged particles.
* lose some energy and change direction as they strike electrons in the crystal.
* owe their penetrating power to their relatively short wavelengths and high energy.
* pass through organs and structures of the body onto a photographic plate
  - the metal without being absorbed
* speed healing of rat spinal cords.
* strike a chromosome in a living cell and ultimately cause the cell to die.
* strip electrons from atoms and leave the electrons free to conduct electricity.
* travel through space faster than radio waves.

Red fish
* are good on shrimp and shad.
* live in dark waters.
