Victoria, BC
South End of Vancouver Island
Site Description:
Victoria
is at the southern tip of Vancouver Island. The Ogden Point
Breakwater is in Victoria Harbor and it is a popular dive site.
The breakwater is constructed of large rectangular blocks.
This and a nearby kelp forest support a diverse array of marine
life. Because of the sharp dropoff, normally subtidal species can
sometimes be seen at very low tides. Our list also includes
species observed by divers on the wall at a shallow subtidal level.
Victoria
has several rocky points of land at the south end of the city.
Some of these points have short stretches of sandy beaches above
them. We group all of these sites together. These
points also contain data from divers at a shallow subtidal level.
The
bays between the rocky points, and the deeper water offshore of
Victoria have been extensively studied by divers and science
expeditions. Our subtidal list groups all of these
observations.

Species List:
Following is a list of mollusk species observed at this
location by members and associates of the club. This is by no
means a complete list of the species which may occur at this site.
Revisions and additions to the data are made as we acquire new
information. When a site contains more than one very distinctive
type of habitat or if multiple sites were included in a single
location, then a
species list for each is included. We indicate
frequency of occurrence based on our observations. This is an
indicator of how likely it is that you may be able to find this
species yourself and is not a formal population survey.
Frequency Code:
(Based on the assumption that you are looking in the appropriate
location where the species
likes to live - on rocks, in sand, etc. Some populations fluctuate seasonally. Ours are based
on the spring/summer seasons.) [4] - Rare - very difficult to find, maybe only a couple found after repeated visits to the site [3] - Uncommon - difficult to find, may not see on every trip but dedicated searching may turn up a few [2] - Common - easy to find, should locate a number of them on any given day [1] - Abundant - very easy to find, large numbers should be seen on every trip
Due
to the nature of the data, these lists will not be rated for frequency of
occurrence. They are incomplete lists.Intertidal - I
