Transcript of Animals that produce Bioluminescence

Animals Welcome to the world of ... DEFINITION:
Bioluminescence animals are living things that emit energy without heat.
It naturally occurs form of chemiluminescence when energy is released by a chemical reaction in the form of light.
A way to communicate using light to affect other animals around them. Some animals that produce Bioluminescence... Why bioluminescent animals make light? Scientists don't know why all bioluminescent forms of life glow. Animals:
click beetles
glow worms Fungi:
Jack O'Lantern mushroom
Ghost fungus Fish:
Cookie-cutter shark Marine Invertebrates:
octopus Micro-organisms:
Vibrionaceae What is Bioluminescence? Most bioluminous organisms are found in the ocean. Sometimes Microorganisms are disturbed causign a natrual wonder known as the milky sea, which causes the ocean to glow. In some cases, this glow is so bright that it interferes with marine navigation. Communication: Fireflies flash at one another in a species-specific pattern, often in order to find a mate. Attracting prey: Some species, like the angler fish, use a luminescent lure to attract other fish. Just like in Finding Nemo :) Disturbed: A few animals light up when nearby animals start to glow (no knowledge of reason for this behavior). Camouflage: In the darker parts of the ocean, it's easy to see the silhouette of what's above you. For this reason, some species produce spots of light on their undersides, which allow them to blend in with the light from above. Mimicry: The cookie-cutter shark has one unlit patch on its underside, which resembles a smaller fish when viewed from below. When a large predator approaches, the shark can take a large bite and then flee. This allows small animals to that are much larger and more powerful than it is. Self-defense: When threatened, some animals release a cloud of bioluminescent fluid, similar to the way squid defend themselves with a cloud of ink. Others use a bright flash to blind predators. Intersting facts... The colours of bioluminescence:
Most of the light created by marine organisms is blue-green in color.
Some other colours can include red, pink, yellow, violet, and white light. Bioluminescence is mostly produced by organisms that live in partial or total darkness. Bioluminescence is mostly produced by organisms that live in partial or total darkness. Bioluminescent light is much more efficient as a light. Bioluminescence is different from: phosphorescence, fluorescence, iridescence and triboluminescence. Where can these animals be found? On land and sea
Bioluminescence is rare on land. with only a few known animals.
In ocean there many diverse animals that produce bioluminescence. here shows many microorganisms together to create a milky sea. Glow Worms: Attracting and catching it's prey Deep Sea Creatures Firefly Surfing with bioluminescent plankton :) References:
