Introduction
Soft corals grow finger-shaped, branched, lobed, encrusting or tree-shaped.
In contrast to stony corals, soft corals do not have a solid calcareous skeleton,
but have small calcareous needles in their bodies as reinforcing elements.
Occurrence: Worldwide in all seas, but most species live in the warm,
tropical seas in shallow water.

Cerianthus filiformis
Tube anemone or Large tube anemone
The cylinder roses do not live in the coral reef,
because they do not share the habitat with corals,
they can be seen in seagrass meadows or on sand down
to a depth of 50 metres.

Cerianthus sp. 1
Cerianthus sp 1
At first glance, cylindrical anemones resemble sea anemones,
but they are very different from them.
Their body is cylindrical and very long.
The specimen shown here is just opening and has not yet fully extended its tentacles.

Cerianthus sp. 2
Cerianthus sp 2
The lower end of the cylinder rose is not flattened like the foot of a sea anemone,
with which it anchors itself to the solid soil substrate, but tubular and slender.
The rose buries this foot in the muddy soil.
It is stuck in a tube that the rose has built itself.
If the tentacles are stimulated, the rose retracts into the tube with a jerk.

Dendronephthya hemprichi
Red soft tree coral
Maximum size : 70 cm
This species is a particularly colourful soft coral.
As is usual with soft corals, it also has various chemical defence substances stored in its tissue, which have a deterrent or even poisonous effect on potential predators.

Plexaurella sp.
Plexaura sp.
I can't write much about size and depth as I didn't get any data on this species of gorgonian.
Biologists only gave me the name sp.
A positive identification requires a microscopic examination.
