Deep Water fish bioluminescence

It grows anywhere from three

Bioluminescence is light produced by living organisms. It is extremely common in the oceans and occurs in all oceans at all depths. Many deep-sea creatures are .

The light is produced by symbiotic bacteria within light-emitting cells called photophores. It is produced by a chemical reaction when a substance called a luciferin is oxidized. When the light is released, the luciferin becomes inactive until it is replaced by the animal. Some animals can make luciferin themselves, or it may be synthesised by symbiotic bacteria inside the photophore.

The photophores, or light-emitting cells, range from simple clusters of cells to complex organs surrounded by reflectors, lenses, colour filters and muscles. The most common coloured light produced by marine organisms is . This is also the colour that penetrates furthest through water.

Deep-sea fish with bioluminescence

In the dark of the ocean, bioluminescence can help organisms to survive. Several deep-sea fish, such as and viperfish, use bioluminescence as a lure to attract prey. The dangling appendage that extends from the head of the anglerfish has a light organ at the end which attracts small animals to within striking distance.

Other fish, such as (myctophids), have light organs on their sides and bellies. Lights on the underside of a fish such as a lanternfish or break up the silhouette of the fish's body. This makes the fish harder to see from below, and helps protect it from predators. Light organs also help fish to recognise mates. Each species of
has a distinct pattern of lights.

Squid with bioluminescence

Bioluminescence is common among squid. It is estimated that two-thirds of all squid genera include bioluminescent species., or photophores, can be found nearly anywhere on the body of a squid. The most common places are the, mantle, head and arms, internal organs (visceral photophores), funnel, and

Water signs do tend to be very truthfull and are very bad liers....
but it also depends on ;you rising sign and moon sign....
for me my rising sign is scorpio*(another water sign) so I come across as being very tough and take no bull shit....
My moon sign is Pisceas so my inner core is very soft and I can sense peoples emotions very easily...
