Does coral lay eggs?
Most coral species spawn annually. They release eggs and sperm into the water on a few nights of each year. The eggs are fertilized in the water to produce coral larvae.
What happens to a coral reef at night?
During nightfall, the coral reef is able to emerge from it shelters in safety. Larvae will also hatch and disperse at night into the plankton.
How are colonies of corals and sponges formed?
Corals and sponges can both reproduce either sexually or asexually. In sexual reproduction eggs and sperm are broadcast into the ocean, where they meet and form a larvae. The larvae drifts around for a bit, and then settles to the bottom. If it is a suitable place, the larvae with turn into a new coral polyp or sponge. Then the coral or sponge reproduces asexually to form the larger colony.
How do coral reefs form what makes them vulnerable to environmental stress?
Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks. Both natural conditions and those created by man is what make coral reefs vulnerable to environmental stress.
How are coral reef born?
Corals have a number of different modes of reproduction. Most commonly, corals reproduce by budding. Basically a coral polyp splits down the middle, and two polyps result. This happens over and over again. Another common mode is sexual reproduction. Corals release egg and sperm into the water, the egg is fertilized, and the resultant creature is called a planula larvae. This planula larvae is basically just a cilliated ball of cells. It settles sometime later, and metamorphosizes into a coral polyp.
What color algae are important in the formation of coral reefs?
Brown algae are important in the formation of coral reefs, as they provide a substrate for coral larvae to settle and grow. These algae also play a role in stabilizing the reef structure and providing food for various reef organisms.
How do corals capture their prey?
Each coral polyp uses stinging tentacles which they wave to capture passing zooplankton, including copepods and fish larvae.
