There are two types (Orders)
of coral you will look at in this section of the lab: rugose
coral and tabulate coral.
The green box contains information about rugose coral. You will need to
use specimens from boxes 7-10 to answer the questions in this section.
|F. Read about rugose
G. Look at the following two diagrams of rugose corals: use the list of terms and the reading, linked above, to make sure you understand how to locate the labelled parts on a specimen and how to describe them.
H. Know the common features of rugose corals:
I. Look at the following links:
J. Look at the specimens from boxes 7, 8, 9 and 10:
These specimens are from Order Rugosa (solitary or colonial, large
calyx with well-developed septa).
Specimens in box 7 are Cyathophyllum, family
The second Order of corals you
will look at today are the Tabulate corals. You will need to use specimens
from boxes 4-6 to answer the questions in this section.
|K. Read about tabulate
corals. Use the diagram below and
the descriptions in the reading, linked above, to help you answer the questions.
Be sure to open the links and
look at each type of tabulate coral. This will help you answer the questions.
L. Look at the specimens from boxes 4, 5 and 6:
These specimens are from Phylum Coelenterata,
Class Anthozoa, subclass Zoantharia, Order Tabulata. These are always colonial
