Have you heard of any animals that resemble flowers but are actually a marine animal? Here we will discuss such a unique, fascinating sea creature, called sea anemone.

Sea anemones are beautiful soft-bodied living aquatic animals related to corals and jellyfish. They are also called 'flowers of the sea' because of their shape. They are named after the anemone flower. Speaking about sea anemone anatomy, they have cylindrical bodies and have tentacles with stinging cells. These stinging cells play a vital role in the sea anemone life cycle; they sting their predators and paralyze them before eating. The floating tentacles are often in multiples of six, keeping the prey in its hollow mouth. The mouth serves as the bottom also. Sea anemone species are invertebrates without a skeleton. There are many varieties of these species that vary in size, color, and reproduction process. Many marine species were found hiding in the tentacles of this anemone.

What is a sea anemone's habitat?

The sea anemone habitat is in shallow coastal waters to deep waters (over 10,058 m) and cold waters. With the help of a pedal disc, they are attached to the hard surface like a rock, seashells, or sometimes on the crab's back. Some species do not have a pedal disc, found burrowing themselves in the sand with tentacles exposing outside.

Who do sea anemones live with?

Sea anemones who don't stay in one place are often found living with many other sea creatures like small fish, crabs, crustaceans, and hermits for their benefit. The relationship between both parties is mutual.

For example, the Hermit Crab and sea anemone maintain a symbiotic relationship. So what is a symbiotic relationship? In this symbiotic relationship, both parties help out each other. The Hermit Crab moves around and stays along with sea anemone for food for protecting themselves from predators.

Sea anemone is one of the longest-living marine creatures. They can clone themselves, which makes them immortal. They may live up to 60-80 years in the absence of predators and diseases. The longest-lived sea anemone is 100 years old.

How do they reproduce?

These sea anemones reproduce every couple of days. The reproduction in this species is either sexual or asexual. In sexual reproduction, internal and also external fertilization takes place. In external reproduction, reproductory cells, sperm, and eggs are discharged into water and combined diffuse to fertilize. In internal fertilization, the female sea anemone fertilizes the eggs. The larva stays inside the female body until they develop tentacles. Once the tentacles are developed, the adult one swims out of the female sea anemone's oral cavity and starts living individually.

In asexual reproduction, the sea anemone's body breaks into two parts by budding or by fission. Longitudinal fission is mainly observed in this species.

How do they communicate?

When the predator attacks the sea anemones species, it gives warning signals to other anemones by releasing the chemical into the water.
