The data collected for the different species that were in
the vicinity of the anemone was run through a Nominal Logistics Test and an
ANOVA test. The results, summarized in Figure 1, showed that there were
no significant correlations between the species, the anemones, nor the
combination of the species and the anemones. However, the p-value for the test
of significance between the species and the anemones was 0.0872 which suggests
that there could be a correlation between a specific species and the anemones.
More thorough tests need to be conducted, on more data, to determine whether or
not there exists a correlation between the species commonly found in Bermuda
and anemones.

The data collected on the dimensions of the anemone was run
through several regression tests in order to determine if there was a
correlation between any of the parts of the anemones. As can be seen in Figure
2,
all of the p-values from the tests show that there are significant
correlations between the anatomical shape of the anemone. The oral disc
diameter has a correlation with the length of the tentacles. Also there
was a
significant correlation between the lengths of the tentacles and with
both the diameter
of the oral disc and the base diameter of the tentacle. All of these
results
make logical sense. If the body of the anemone is bigger then it is
expected
that the tentacles would be longer. Same principal applies for the
length of
the tentacles and the base diameter of the tentacle. However the
regression wasn't significant so no dimensions could be predicted with
significant accuracy. Figure 2: Results of regression tests on the dimensions of the anemones.

The density of the anemones in Whale
Bone Bay
was found to be 0.01 anemones per square meter, or one anemone in a 100 meter
squared area. This means that if a 10x10m quadrat or a circle of radius 5.64m
was randomly placed in Whale
Bone Bay
there would only be 1 anemone in the designated area. The density
suggests that
the anemones are widely dispersed, however when the data was being
collected
most of the areas that contained anemones, contained more that one
anemone.
In the data collection there were a total of seven areas that contained anemones and only
three of
those contained single anemones. Thus the density is just a rough
estimate for
the total amount of anemones that would be expected in an area, but not
useful
to describe the distribution of the anemones. The area of Whale Bone
Bay can be estimated by a circle with readius 102m, and by extraplating
the density, 316 anenomes would be expected to be found in the bay.
