SOFT CORALS

Soft corals are members of the order Alcyonacea. These corals are found in a variety of colors. Soft corals are found mainly in tropical waters around the world mainly in coral reefs .

Soft corals will defend their space on the reef by secreting a chemical that inhibits the growth of neighboring coral.The most common form of reproduction in soft corals is asexual by budding, a process in which the parent coral produces a miniature replica of itself that eventually breaks away and attaches to a hard structure. Most soft corals contain the symbiotic algae zooxanthellae within their bodies, and receive nutrients from the algae when exposed to high light levels.

--Homework: Grammar, units 11 and 12 about the simple past and a handout with some regular verbs to check their pronunciation. It would be a very good thing to have a list of regular verbs in the past classified according to their pronunciation in /t/, /d/ and /Id/. We had a great deal of practice of this pronunciation activity.
