Interesting Information about Sea Anemones
Sea Anemones are named after
the Anemone flower. They are a predatory animal that releases a
toxin to paralyse its prey. The prey is then moved into the
anemones gastro vascular cavity. The poison secreted by a sea
anemone affects fish and crustaceans. The Clown Fish or
Anemonefish however has a mutually symbiotic relationship with
the sea anemone, they are not affected by its poison and live
among its tentacles, indeed laying their eggs on the anemone
itself. The clownfish uses the sea anemone as a form of defence
from larger predators.
Sea Anemones - Anatomy
The sea anemone has just one
external opening. This single opening acts as both a mouth and
an anus. All waste and undigested material is excreted through
this opening. A sea anemone has no sense organs, its nervous
system is very primitive but it does have nerves and muscles.
The anemone doesn't have a skeleton, it keeps itself stable by
closing its mouth enabling it to stay rigid.
Sea Anemones - Movement
Can a sea anemone move? Although
sea anemones usually remain static, they can use their pedal
disc to move slowly flexing their body or using their tentacles
to swim slowly to another location. They can attach themselves
to a rock, the sea bed or the shell of a crustacean, a hermit
crab for example. A sea anemone will only move location if they
are attacked by a predator or the conditions of the water are
unsuitable.
