Magnificent sea anemone

Heteractis magnifica or the magnificent sea anemone (aka. Ritteri anemone) is a member of the Family Stichodactylidae, which are best known for forming symbiotic relationships with a variety of clownfish. They inhabtit the marine waters of the Indo-Pacific area.

In total, there are 100,000 kinds of sea anemones. Anemones are polyps that attach to hard substrates such as rocks. Some can grow up to 2 meter in diameter. Mostly their body coloration are yellowish brown, red, and dark brown.

Anatomy


The internal anatomy of Heractis magnifica is the same as other sea anemones, and is much simpler than most other animals. It is a gastropida cavity. It eats and excretes through an oraphis that serves as both the mouth and the anus. The nervous system is not centralization and maintaining homeostasis to various stimuli. Anemones' size is 1¼ cm (½ in) to 2 m (6 ft) in diameter. They can extend freely and have between 10 tentacles to hundreds.

Unlike some other Cnidarians, such as the stony coral, anemones do not possess a skeletal support system.

Reproduction


Sea anemones can reproduce both a sexually and an asexually. an asexual reproduction creatures and plants have no sexual organs that by budding, binary fission what involves into two halves and pedal laceration. it breaks off to small anemones.

In sexual reproduction males release sperm and females release eggs into the water, then fertilization occurs. The eggs or sperm are spout through the mouth. The eggs develop through the planula. They flow down somewhere which can settle down for living and grow through a single anemone. Mostly sea anemone which live in captivity lives long time about 65 years, big sea anemone that growing in the wild lives about 100 years.
