- 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.
The two main types found in the Caribbean are coralline and calcareous algae. Coralline algae spread out in a fine layer across the surface of the coral, trapping particles of sand and helping to firm up the coral. Calcareous algae grow upwards from the coralâs surface.
