Marine bioluminescence :
heatless light generated chemically by marine organisms. Bioluminescence is exhibited by a wide variety of oceanic organisms, from bacteria to large squids and fishes. The light is emitted when a flavin pigment, luciferin, is oxidized in the presence of luciferase, an enzyme also produced by the organism. (The chemical system is like that of fireflies.) The light produced is usually blue-green, which in the electromagnetic spectrum is near the point of maximum transmission for seawater and which is most visible for many deep-sea organisms.

NEW SPECIES FOUND IN 2017 : This is a Synalpheus pinkfloydi, a newly discovered species of shrimp named for Pink Floyd. The shrimp uses a bright pink claw to create a sound loud enough to kill small fish

SIMILARITY BETWEEN HUMAN AND TREE
A tree needs the four basic elements in order to survive -- soil, water, air, and fire (sun). Human beings also require the same basic elements. Let's examine these, one at a time:
SOIL
A tree needs to be planted firmly in the earth. The soil is not only the source through which nourishment is absorbed, but also provides room for the roots to grow.
Humans require a strong home base, where values and morals are absorbed, and which provides a supportive growth environment. In a world rife with negativity; we need a filter, a safe haven to return to and refresh.
WATER
Rain-water is absorbed into the ground and -- through an elaborate system of roots -- is carried throughout the trunk, branches and leaves of the tree. Without water, the tree will whither and die.
Deprived of water, a person will become dehydrated and ultimately disoriented, even to the point where they may not be able to recognize their own father.
AIR
A tree needs air to survive. The air contains oxygen that a tree needs for respiration, and carbon dioxide for photosynthesis. In an imbalanced atmosphere, the tree would suffocate and die.
We use our senses of taste, touch and sight to perceive physical matter. (Even hearing involves the perception of sound waves.) But smelling is the most spiritual of senses, since the least physical matter is involved. As the Talmud says Smell is that which the soul benefits from, and the does body not.
FIRE
A tree also needs fire -- sunlight -- to survive. The absorption of energy from the light activates the process of photosynthesis, a chemical reaction that is essential for the growth and health of the tree.
Humans also need fire -- warmth -- to survive. This is the warmth of friendship and community. People absorb the energy of peers, friends, family, neighbours and associates -- and channel that into identity and actions.
