3p Daisy Coral (Siphonogorgia)
is a Indopacific coral genus of the subclass Octocorallia. We find
the coral in the tropical western Pacific in the Philippines and
Malaysia and the Red Sea.
Siphonogorgia colonies are similar with their slim, richly
branched growth of a gorgonian have, however, with no rigid axial
skeleton, but are stabilized by the internal water pressure. Main
trunk and large branches are without polyps. As with all
Octocorallia, they have Siphonogorgia polyps eight tentacles. The
polyps can be completely withdrawn into the branches. The branches
are densely equipped with spindle-shaped sclerites, so they feel
drawn together. Siphonogorgia
are usually splendid yellow, red or purple colored. The color of the
polyps is often different from that of the branches.
4p Sundial (Architectonica
common name the clear or perspective sundial shell, is a species of
sea snail, a marine gastropod mollusk in the family
Architectonicidae, which are known as the staircase shells or
sundials. It is
considered moderately common and usually found subtidally on sandy
and muddy bottoms, from depths of 10 to 120m, mostly between 10 and
65m. An unmistakable snail, the shell coils form a flat disc-shape
with a flat base. The shell is beautifully banded in shades of black
and brown. The body is striped too, to match the shell. The
operculum is made of a horn-like material.
50p The Marble Sea Star (Fromia monillis),
or Marble Starfish, is one of the more common of the Fromia species,
its coloration making it one of the more striking of all the sea
stars. Its central disc will have an orange to deep red color, while
its arms have cream-colored spots with a red edging. It is found
over sandy substrates, on rocks, and sometimes climbing on anemones.
It is constantly foraging for micro-organisms and detritus to eat,
so the aquarium should have ample amounts of live rock. It generally
lives alone, but if the aquarium is large enough to support more
than one, it will tolerate others of its own species.
