i'm interested in knowing knowwhether pink n red corals are naturally in this colour or are they dyed?

Answer 1

Corals are natural color.
I hope you can visit the Carribbean some day and just snorkel if you don't do diving. Fabulous scenery there.

Answer 2

The red coral lives forming tree-like colonies with irregular shape branches. It has a calcium skeleton which may reach a lenght of 2 feet, though normally is well under this size. Those branches are formed by white polips, each one with 8 tiny tentacles. The branches are covered with a bright red tissue, though sometimes it can be white or even yellow. The inner skeleton can be found in all shades of red, including white and black.

This coral can be misidentified with the "false coral" (Parerythropodium coralloides) which appears encrusting dead gorgonians skeletons, but it can be identified because of its soft texture and the different polips. Red coral can also be confused with a briozoans colony called Myriapora truncata, though its color is bright orange, the branches are regular and flat ended. Once dead its color fades to white, while the red coral retains its bright red color.

Red corals can be found in the western Mediterranean Sea and in the Adriatic, inside dark holes and crevices. It can be found also at great depths. In the past it abounded in caves over 30 feet but it is rare now. It can be easily found from 100 feet down to 300 feet.

Red coral is formed by two types of polips, the ones with tentacles, in charge of feeding, and other ones, similar to tiny tubes, which are in charge of keeping water flowing through a pipeline system inside of the colony.

They reproduce in two ways. There is the fecundation of the ovules, then the mothers let the free swimming larvae go, which then adhere to the rock substrate nearby, starting a new colony by partition of itself.

As the skeleton is formed by tiny calcium spicules, it has a glassy consistence, very easy to work with, so it is very appreciated in jewelry, the reason of its disappearance from surface waters. Coral has been used for ages, and coral ornaments had been found in graves 25.000 years old in Wiesbaden (Germany). It has been found also in the ancient Egyptian graves.

The price of coral is higher the stronger the branches are and the lighter the color. By this reason corallers risk their live to get it from depths of about 300 feet and more. Actually red coral is collected at a rate of about 60 tons a year, but the yield is very low, the dredges used to capture it retain only 20% of the extracted coral, and only a small part of it is useful. The rest is vainly lost in the Sea.

Answer 3

There are pink and red corals. They exist naturally.

Answer 4

they come out of the ocean with these colors.
