There are up to 800 tentacles on the oral disc. They can be a brownish-gray, mauve, or green; and some specimens are found with beautiful blue, purple, and mauve tips. The tentacles are very long and taper at the tip. They are so long that they typically become intertwined.

flowering plant genus, 1550s, from Middle French anemone (16c.) and directly from Latin anemone , from Greek anemone "wind flower," literally "daughter of the wind," from anemos "wind" (cognate with Latin anima ; see animus ) + -one feminine patronymic suffix. According to Asa Gray, so called because it was thought to open only when the wind blows. Klein suggests the flower name perhaps originally is from Hebrew (cf. na'aman , in nit'e na'amanim , literally "plants of pleasantness," in Is. xvii:10, from na'em "was pleasant"). Applied to a type of sea creature ( sea anemone ) from 1773.

Habitat: Distribution / Background The Bubble Tip Anemone Entacmaea quadricolor was described by Rüppell and Leuckart in 1828. The Entacmaea genus is a member of the Actiniidae family. The Entacmaea quadricolor is found in the Indo-Pacific Ocean from the Red Sea to Samoa. This anemone is widespread and common, and is not on the IUCN Red List for endangered species. Some common names they are known by are Bulb Tentacle Anemone, Bulb Tip Anemone, Bulb Anemone, Four-Colored Anemone, Rose Bubble Tip Anemone, Rose Anemone, Maroon Sea Anemone, and Maroon Anemone.

Urticina crassicornis produces by both asexual and sexual reproduction . In the Atlantic populations, eggs and sperm are held and fertilized within the body column. The young are brooded between the mesenteries of the body and are emitted as smallish, well developed, young anemones. Spawning occurs in the spring amongst Puget Sound populations, when eggs (yolky,  mm in diameter) and sperm are released into the sea for fertilization. Urticina crassicornis's major sperm chromosomal proteins have been found to be two specialized histone H1 proteins which indicate a strong relation to the chromosomal proteins of bird and amphibians. [7] After fertilization, a solid and ciliated blastula is created due to superficial cleavage. Six days following fertilization, a cone-shaped and benthic, larval planula develops. These planula then settle onto small rocks or the empty tubes of some annelid worms and rapidly develop into small anemones. 12 days after settlement, 8 tentacles appear. Further growth is slow – two months after settlement, 12 tentacles appear and the anemone is  mm in diameter; one year after settlement, the anemone has 35 tentacles and is 10 mm in diameter. Growth is proportional to food intake, not age. When starved, this anemone can stay alive for 9 months but does not grow. Urticina crassicornis is sexually mature with a diameter of 10 – 15 mm, being at least one year old. [1]
