Parazoanthus darwini is a
Description
Parazoanthus darwini features polyps with colorful tentacles that exist in double rows
Distribution and Habitat
Parazoanthus darwini grows in colonies which can range from covering a small area to a much larger area. In addition, the corals grow over sponges which is their usual substrate and in patches. If the corals completely cover the sponge, they can extend their growth to the rock substrate. These colonies have about 40 polyps, and the coral has been found with mostly sponge substrates and some rock substrate. Parazoanthus darwini tends to dwell in relatively shallow waters and especially on rock crevices within rock walls as well as the base of the rock.[1] The coral has been located within the Galapagos Islands. In the archipelago, the islands of Espanola, Fernandina, Floreana, Marchena, Isabela, San Cristobal, Santa Cruz, and Wolf have had the presence of Parazoanthus darwini in their waters. Here, warm and cold ocean currents as well as upwelling currents exist which subsequently leads to the Galapagos Islands to remain isolated from other regions but also results in high levels of biodiversity.[1]
Biology
The coral’s growth into colonies plays a significant role in the reproduction of Parazoanthus darwini. All zoanthids with the exception of Sphenopus breed in colonies via budding.[8] Just as other corals, Parazoanthus darwini reproduces asexually. The polyps embedded in the coenenchyme end up germinating from the parent polyps in order for more colonies to arise allowing for more of the reproduction of Parazoanthus darwini.[9] While the coral is still in its early stages of development, the ectoderm integrates particles such as sponge spicules and sand, which enables the coral to maintain its skeletal structure.[2]
Taxonomy and Morphology
The parazoanthus darwini is a part of the order Zoantharia.
