The anemones mouth
Printed on C-type Fuji Matt professional archival photographic paper.
A beadlet anemone with tentacles expanded sits and waits for prey to stumble by. Any contact with a tentacle triggers the stinging cells that ensnare and subdue the prey as the tentacle directs it toward the central mouth. This one was peppered with sand grains from waves washing through - a side effect of living where a fresh supply of prey is brought right to you.
