Theophrastus, Aristotle's successor, was the first to take an interest in coral stone, which he considered to be a petrified plant. Until the 17th century, the stone is perceived as a curious underwater shrub whose milky sap was observed in 1613 by a gentleman from Lyon, France.
In 1706, the count of Marsigli speaks about the flowers of the coral, the coral stone was recognized as a kind of animal close to the octopus by Jean André de Peysonnel, in his memoir of 1744. Over the centuries, the knowledge of the stone has been refined. Réaumur and Jussieu, who initially contradicted the idea of stone as an animal, finally recognized this thesis as soon as they learned of Tremblay's work on the freshwater hydra. In 1863, studies by Lacaze-Dythier researchers demonstrated the validity of this thesis.
Source of many questions, L'Oréal Recherche wished to carry out a study by scientific researchers to verify the action of UV filters on corals. As sun creams have been criticized for years for their potential harmful impact on corals, the aim was to find a result that could reveal the real consequences of sun creams on biodiversity. The source of the questions is notably due to zinc oxide and titanium oxide which cause the spread of bacteria or viruses.
The result of this work reveals an absence of harmful impact of UV filters on the photosynthetic activity of corals. The L'Oréal group, which is committed to biodiversity and the impact that their products can have on it, took coral reef bleaching into account in evaluating this scientific test, as coral bleaching is synonymous with dieback. Even when exposed to higher levels of bleaching than in the marine environment, corals retain their photosynthetic capacity.
Legends surrounding Coral
As an uncommon marine animal, there are many mysteries surrounding this species. In Ovid's "Metamorphoses", the Latin poet relates the origin of the coral stone in the story of Perseus and Andromeda. After saving Andromeda, Perseus places the head of the gorgon Medusa on a bed of seaweed, his eyes towards the ground, so as not to endanger the population. The gaze of the gorgon petrified the algae and gave birth to this stone. This is why, in Greek, the stone is called "Gorgeia", in relation to the gorgonians.
Symbolically, the stone, according to cultures and times, has several meanings. All over the world, corals have been a source of beliefs and the different existing species participate in maintaining the magic. The Romans made children wear necklaces to protect them from injury. The tradition lasted for years until the medieval period. The use continues in Italy, especially to treat infertility problems. A symbol of fertility, it is always recommended that women who wish to become pregnant wear a small coral horn around their neck.
In China, the coral stone was a symbol of wealth and high social status. The Amerindians considered it as a sacred stone, symbol of life force energy and protection against the evil eye. In Greek mythology, it was a gift given to men by the demigod Perseus.
Legend has it that after killing Medusa, he threw his head into the sea, and his blood turned into red algae which then formed corals. Among the Romans, this stone holds an important place in literature. Pliny the Elder advised people to wear this stone to repel people capable of offering all kinds of temptations. The Gauls were reputed to use coral stone in the manufacture of their shields, helmets and weapons to gain courage on the battlefield.
The body of each polypier is about 2mm long, similar to a tubular bag with 8 inner compartments, with a hole with 8 finely serrated tentacles. This bag is inserted into a connective tissue, the so-called coenorsarc, in which it can completely retract like sea anemones. All the individuals in the colony or superorganism are interconnected by a system of vessels running parallel to the axis of its "branches" and carrying a whitish fluid.
When danger approaches, the entire colony is enclosed in the coernosarc. This explains Marsigli's interpretation of a blooming of "flowers" as individuals reappearing once the danger has passed. The foot of the polyps and the base of the coenosarc secrete calcareous spicules whose successive deposits constitute like an external skeleton to the superorganism. This last thus resembles a shrub without leaves, whose petrified branches comprise a kind of gelatinous bark.
In the same superorganism, all individuals are of the same sex. However, some branches of a "tree" sometimes bear "individuals" of different sexes. Coral superorganisms multiply and spread by sexual reproduction. Each egg matures at the end of a stalk in the stomach cavity of a female polyp. It is there that the spermatozoa spread in the water by the male polyps come to fertilize it. The result is an elongated microscopic larva which in the ocean becomes a kind of small jellyfish. It is in a coral reef that we find coral, the Great Barrier Reef is the best known ecosystem.
The chemical composition of corals is as follows Calcium carbonate, CaCO3, with magnesia and organic substances. Hardness: 3-4. Density: 2.6 to 2.7. All over the world, deposits are found in the archipelago of Malaysia, in the Bay of Biscay, in the Canary Islands, in Japan, in the Mediterranean Sea, on the shores of the Red Sea and in the north of Australia.
