Flower, I understand your need to call them corals.. And yes I tend to think of them that way too...... And today we all just refer to them that way..... I was just stating what I have read about the little buggers over the years.
The first little paper back book I ever got about trying a crack at this crazy obsession we all have was one published in the early days of modern reef keeping. I wish I could find it today. I think the book was the late 80,s early 90,s.......
This one of the first things I read about these guys was their placement in the coral family's. They did not fit.
This was the issues with where they where in the evolutionary chain.......Here is a quote from another source.
"Known as Mushroom or Disc Anemones, and Mushroom Corals, here is profile information on Order Corallimorpharians - Family Discosomatidae / Actinodiscidae species corals. Although considered to be halfway between anemones and stony corals, members in this family more closely resemble soft corals, and therefore are commonly grouped in this category.
In reading some of these types of literature this shows why I see a reluctance to call them true corals................. This categorization being "Although considered to be halfway between anemones and stony corals" Sort of puts them in a place just as closely related to a anemone as to a coral.
Most of us would not call call an Anemone a coral would he and these guys are just as closely related to them as they are what we call the true corals.....
Interesting...my books calls them corals, with no reference to anemones...the only one
I would, but not my books... even remotely call related to the anemone would be the plate coral, which is considered a mushroom...since it moves and goes where it wants to.
I think what your book was referring to is the little colonies that live inside coral like the Xenia...the little colonies make up the whole coral. While a mushroom coral is a colony all to itself instead of being a part of a collective, LIKE an anemone, however not related to them.
I see no reference at all that they are an "in-between"...do you have an article where I could read up on this on line?
