Biological Tuesday |
Yes, its another creature Tuesday and this picture comes from
the Oregon coast. This is a Sea Anemone. You can find these down in the rocks and
crevices of the tide pools. These things hang around and wait for small
fish to swim close enough and they grab them with their
tentacles.

Anemones are animals, and not plants. They have a mouth, and use
their stinging tentacles to stun prey and shuffle tid-bits
towards the mouth. They can survive without Anemonefish, although
Anemonefish cannot survive without them. Those that house
anemonefish do not sting their boarders. Many studies have been
carried out to determine how this is possible, but the most
commonly accepted reason is that the Anemonefish coats its scales
in mucus from the host, tricking the host into thinking it is
just a part of it. "Eww, mucus."
