example:
To search for laminaria species found in sublittoral zones,
highlight the field in the drop down menu for genus (or species)
and type "laminaria," and in the next drop down
menu choose field for habitat and type "sublittoral."
Fields:
| Species |
A
category used in the taxonomic classifcation of organisms
that consists of a group of similar organisms that can

| Habitat |
Littoral:
The area of the shore that is occupied by marine organisms
which are adapted to or need alternating exposure to
air and wetting by submersion, splash or spray. On rocky
shores, the upper limit is marked by the top of the
Littorina /Verrucaria belt and the lower limit by the
top of the laminarian zone (Lewis, 1964). It is divided
into separate subzones, particularly marked on hard
substrata. Cf. 'intertidal'.
Eulittoral:
The main part of the littoral zone characterised by
limpets, barnacles, mussels, fucoid algae (other than
those characteristic of the littoral fringe), with red
algae often abundant on the lower part. It lies above
the main population of Laminariales. Zonation within
the eulittoral is variable, with two to four (commonly
three) belts often clearly discernible. 1) (lower) The
lower belt of the eulittoral subzone, bordering the
sublittoral fringe, and generally dominated by Fucus
serratus and red algae. 2) (mid) The broad middle belt
of the eulittoral subzone, usually characterised by
limpets and barnacles or Mytilus and filamentous red
algae in exposed situations, or dominated by fucoids,
often with clumps of large mussels present, in shelter.
3) (upper) The narrow upper belt of the eulittoral subzone,
often very variable in character. (from Hiscock, 1990).
Sublittoral:
The zone exposed to air only at its upper limit by the
lowest spring tides, although almost continuous wave
action on extremely exposed coasts may extend the upper
limit high into the intertidal region. The sublittoral
extends from the upper limit of the large kelps and
includes, for practical purposes in nearshore areas,
all depths below the littoral. Various subzones are
recognised (based on Hiscock, 1985.) (Cf. 'subtidal').
Also "supratidal."
