Introduction to Sea Anemone

Sea Anemone are predatory and as you can tell from their name, they live in bodies of water. They are related to both jellyfish and corral. It is a type of polyp that is attached to a surface in the water. They are very small, often less than one inch in diameter. The largest ones are only about 1 ½ inches wide. However, they can be up to 6 feet tall.

Sea Anemone Description

Sea Anemone offer hundreds of tentacles that allow them to identify their surroundings. They can also sting things around them and release venom through those tentacles. They can be very colorful and often look like flowers. They are often various shades of red and pink. Others are white in color and they can have a variety of overall appearance features.

Class  Anthozoa
Subclass  Hexacorallia
Order  Actiniaria

The body consists of a foot that is shaped like a pedal. That is what allows them to secure and stay attached to their location in the water. They have a body that looks like a long cylinder. The tentacles are all around the mouth that is very hard to see. There are over 1,000 species of Sea Anemone and that is why their appearances can be so varied.

Sea Anemone Distribution

You will find them living in all of the oceans around the world. They can live in a variety of water temperatures and at a variety of different depths. They are mainly found though in the coastal waters that are considered to be tropical. They tend to live in areas that offer plenty of green algae. Due to their venom there are very few types of aquatic life that will consume them.

Sea Anemone Behavior

Experts believe that the relationship between the Sea Anemone and green algae is very spectacular. It ensures that both are able to survive. This entity ensures that the green algae has a safe place to thrive in the water. It also gives them access to sunlight so that they can thrive.

In exchange though the green algae offers plenty to the Sea Anemone too. This includes both oxygen and glucose. Those are both byproducts of the photosynthesis process of the green algae. They have a similar type of relationship with Clown Fish.

They have been known to sting humans such as scuba divers. Most of the time though the toxins they deliver from the venom aren’t powerful enough to really affect a human. For those that are sensitive to them though it could be a factor.

Sea Anemone Feeding

Due to the large polyps that the Sea Anemone display they are able to consume prey that is much larger than they are. They mainly consume fish as they approach them. Since they blend in so well with the surroundings the fish and other prey come along and don’t even know they are in danger.

The tentacles from the Sea Anemone inject them with venom which immobilizes them. In addition to fish they consume zooplankton, crustaceans, larvae, and worms. They are opportunistic and they will consume food any time it come along. If there is no food they can’t survive as they aren’t able to mobile their bodies.

Sea Anemone Reproduction

For the Sea Anemone a complex process called lateral fusion is what takes place for reproduction. This involves the side of the entity opening up and then an identical part being created that is a second living one.

They will release eggs and sperm into the water and then the sperm finds the eggs to fertilize them. This is how they take part in reproduction as well. However, only a very small number of their eggs will survive to the age of maturity. They are able to live attached to rocks or the bottom of the sea for up to 50 years.
