Alphabet Challenge :: C :: Corals

Pitiful Posting and the Alphabet Challenge

Corals, Coral Pictures, Coral Facts – National Geographic.

Most people may not realize that coral reefs are centered around actual organisms. Coral polyps are invertebrates (related to sea anemones and jellyfish) surrounded by a limestone skeleton called a calicle. The polyps attach to rocks, bud and clone, and begin the basis of a coral reef. Once attached to one another, forming a colony, the polyps act as a single organism. The joining of colonies over hundreds and thousands of years is what form coral reefs. A single polyp can live for 2 years to hundreds of years and colonies can survive 5 years to several centuries. Since coral polyps are actually translucent animals, the bright colors come from the association with zooxanthellae algae.

When stressed by such things as temperature change or pollution, corals will evict their boarders, causing coral bleaching that can kill the colony if the stress is not mitigated

The destruction of coral reefs is becoming an issue leaving coral in an endangered status.

Corals are so sensitive to climatic change that scientists study coral reef fossils to construct highly detailed chronologies of prehistoric climate patterns.

Photosynthesis from the algae support the coral for the most part, but they also posses barbed, venomous tentacles that can be used to capture zooplankton and small fish. Though coral covers about 1% of the ocean floor, they support about 25% of all marine creatures. Within 30 years, threats to coral reefs (pollution, sedimentation, global warming, etc.) could kill 30% of the remaining coral reefs.

Pitiful Posting and the Alphabet Challenge

One of the great things about WordPress is the little calendar that shows you the days on which you’ve posted. One of the bad things about it is looking at that same calendar and seeing how sad and empty it looks. -_- To get myself back into the swing of posting, I’ve decided to start an Alphabet challenge. Hopefully I can kick-start myself into a blogging groove again with this. Below I’ll list each day, the letter, and as I pick my topic, I’ll come back here and add it. The one day that I probably won’t post on is June 8th. Blasted GRE. If I absolutely cannot find an animal or drug or something that follows the days letter, I’ll get creative.
