- 4 March 2014 7. What are the little black worms that get into houses at this time of year? They are about 5 to 8 cms long and usually come in at night. They crawl around for a while (sometimes up the wall) and then die. If disturbed, they curl into a tight spiral.
These are: Major regions of coral reef development. (1) The Indo-Pacific-Includes most of the Indian Ocean (excluding the Red Sea), and the western Pacific. (2) The Wider Caribbean (tropical western Atlantic) - Includes Florida, The Bahamas, Caribbean Sea proper, and coastal waters off northeastern S. America.
Corals are found across the worldâs ocean, in both shallow and deep water, but reef-building corals are only found in shallow tropical and subtropical waters. This is because the algae found in their tissues need light for photosynthesis and they prefer water temperatures between 70-85Â°F (22-29Â°C). There are also deep-sea corals that thrive in cold, dark water at depths of up to 20,000 feet (6,000 m). Both stony corals and soft corals can be found in the deep sea.
