The extinction of the red coral will have a huge impact on economic of certain countries that dependent upon the Corallium rubrum. Besides that, tourism of countries that counting on the beauty of Corallium rubrum to attract tourist would also be affected by the declining rate in Corallium rubrum population. However, the most saddening impact is the loss of habitat towards organisms that depend upon Corallium rubrum as its shelter. Thus, this will eventually affect the balance in aquatic ecosystem
By definition, symbiosis is the close and often long term interaction between two or more different species. The word symbiosis is derived from the Greek words, sym (together) and bio (life). German biologist Anton de Bary is the scientist typically credited with coining the term in the middle of the nineteenth century, though also an important contribution was made by his contemporary, Albert Bernhard Frank. Frank, however, instead used the term symbiotism. De Bary introduced the term to discuss
fact, these exceptional animals have true tissues, develop from embryonic gastrula, and it acquires multicellular reproductive structures, which is what makes them different from sponges. Cnidarians have only three classes: Hydrozoa, Schyphozoa, and Anthozoa. It is easy to remember Cnidarians are recognizable as jellies and anemones, and most common are jellyfish. The embryonic endoderm and ectoderm are what make up the two distinct body layers of Cnidarians. Since Cnidarians are organisms with two tissue
this paper will explain the reproductive evolution of soft corals in a broader array that will pertain to the scientific order Alcyonacea, or all types of soft corals. What are soft corals? Soft corals are grouped in the phylum Cnidaria, class Anthozoa, and order Alcyonacea. Their distinguishing characteristic is that their polyps always bear eight tentacles which are on both edges fringed by rows of pinnules (Fabricius and De’ath, 2002). The common name “soft coral” comes from the fact that
