The Tuberculate Night Anemone is a rare saltwater anemone. Since it is an invertebrate it has no skeleton or backbone. They are one of the many predatory animals underneath the oceans surface.[2] Since these anemones' are rare they are hard to find. But they are usually found in low tide and shallow waters.[3] Sometimes the anemones are found in really deep parts of the ocean, and they are even found in coral reefs. The Anemones are home to the Clown Fish that form a symbiotic relationship.[4] Clown Fish use the anemones as a home. It is a place of safety for them but its not free. In return the Clown Fish cleans the anemone's tentacles. the fish also eats the anemones' left overs for food. The Clown Fish is the only fish that is immune to the poison on the anemones arms (tentacles). Scientists have actually found a special type of gel called mucous that coats the scales and outside of the Clown Fish. The mucous helps protect the fish so that it can live amongst the anemone. [5]


The Tuberculate Night Anemone is a rare type of an unusual sea anemone; and is not very common. They usually anchor themselves on the hard reef substrate. The tuberculate night anemone is a small invertebrate which measures up to about two inches vertically and up to 4 inches horizontally. This anemone has a translucent, and white central column going all the way down. This particular sea anemone has a orange and white center. The Tuberculate Night Anemone is cylindrical in shape. The tuberculate night anemone has tube like growths which are in cluster formations and are scattered along the lengths of each of its many columns. It is crowned by long, stretchy tentacles. The tentacles are even translucent, and have hard to see little white spots along each of their tentacles.[6] All anemones are part of the Phylum Cnidaria. Actinoporins are the little sensory hairs on each of the anemones arms. When they brush up against something that feels like a threat to their habitat or life they react but squirting poison into the predator. The same situation occurs with its prey and food. The tentacles on anemones are all filled with cnidae. The anemone's mouth is surrounded by tentacles, each of the tentacles is to filled with cnidocytes. The cnidae which is the little factors that make up the powerful you feel when you get stung by a anemone are called nematocysts. Each of the little nematocysts is made up of a tiny microscopic packets with little toxins in each of them. actinoporins— an inner filament and an external sensory hair. [7]


The Tuberculate Night Anemone reproduces through lateral fusion, asexual reproduction, as well as sexual reproduction. Male and female sexes for a anemone are separate. Lateral fusion is when a replica of the anemone starts to grow out the side of the already grown anemone. The new anemone grows until it is big enough and then finds a new place to live, such as a rock or possibly a crab's shell. They also reproduce other anemones' through sexual reproduction. This is a process where the anemone releases its sperm and its eggs into the open waters. When doing so the sperm and eggs make free-swimming larvae.[8]

Asexual reproduction for the anemone happens through budding. The process starts by the anemone pulling itself apart into two parts. Then it goes through another process called pedal laceration. During which many tiny pieces from the pedal disc are broken off and they all grow into separate little anemones. The sexual reproduction for the anemone goes like this: the male anemones release sperm from its mouth into the water which send a message to the female to let go of her eggs which she does so through her mouth. Then once both of the organs tough fertilization occurs. Then the eggs that are fertilized turn into a planula. The planula then will settle down into a comfortable environment and the process starts all over again.


All Anemones are in the phylum of Cnidaria. Anemones attach themselves onto objects such as coral, rocks and rarely small animals like crabs. [9]They attach themselves to the to the bottom by an adhesive foot. Anemones usually stay in the place they have been living in forever. But sometimes the anemone becomes discontent with the location that it is at. Or it gets annoyed with the predator that is bothering them. In that case the anemones can uproot their bodies and scoot away to a new home. They uproot themselves and move away by using motions where their bodies are in constant motion by swinging back and forth.[10]

They like to eat and consume worms and zooplankton, also mussels and small fish. The Tuberculate Night Anemones anchor themselves on a platform called a pedal disk. These specific anemonies have single polyps; each of their polyps have tentacles around their mouths. All Anemones, have nematocysts; each of the nematocysts have the ability to sting.[11]
