Sea anemones are some of the most interesting rock pool creatures that we see at Dalebrook, Kalk Bay. There are many different species of sea anemone, and they come in so many colours, shapes and sizes that sometimes people aren’t sure if what they’re looking at is a sea anemone at all!
My favourite thing about these creatures is that they masquerade as beautiful undersea flowers while waiting to grab a little fish or crab to eat.
These carnivores can “walk” (in other words, move very slowly!) using a strong “foot” which they use to attach themselves to rocks. This is called a basal adhesive disc.
Most of the time when we take children down to Dalebrook to explore, it is at low tide. While some of the sea anemones are happily waiting submerged in rock pools for the tide to come back in, others are left exposed on the rocks and so they have closed their bodies up to protect themselves from drying out. They look a bit like blobs of jelly.
Here are some pictures we have recently taken of sea anemones at Dalebrook and in the tank at the Shark Education Centre.
