Anthozoa is a class within the phylum Cnidaria. Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. More than 6,100 species have been described.
The name comes from the Greek words άνθος (ánthos; "flower") and ζώα (zóa; "animals"), hence ανθόζωα (anthozoa) = "flower animals", a reference to the floral appearance of their perennial polyp stage.
Biology and anatomy
Like those of other cnidarians, the individual polyps have a cylindrical body crowned by a ring of tentacles surrounding the mouth. The mouth leads into a tubular pharynx which descends for some distance into the body before opening into the gastrovascular cavity that fills the interior of the body and tentacles. Unlike other cnidarians, however, the cavity is subdivided by a number of radiating partitions, or mesenteries. The gonads are also located within the cavity walls.

Enthos
by: The InsyderzThe walls are closing in on me
I'm getting dizzy and it's hard to see
My lungs are heavy and it hurts to breath
Can't lift my head, stare at me feet
It's all getting clear
You tell me I don't want to hear
I know you see my eyes the fear
I clench my teeth and shut my ears
I've tried it all and I'm sick of fighting
The words of truth made clear in writing
Oh, Lord deliver me!
I want to be free so I may mount up on wings
For once I don't feel so dead
I can breath again and lift my head
No longer bound to a life once led
True to everything he said
I want to fly all around
And not look back or touch the ground
I want to fly up so high
And look deep into Your eyes
Gravity means nothing to me
Just another lock broke free
Against my face the wind will blow
To the world Your glory shows
I'm tired of Satan's attacks
Get the devil off my back
Down the tunnel I see light
Nevermore will I have to fight!
Pick it up (3X)
Hey (4X)
Oh, Lord deliver me
I want to be se free
I want to fly so high
Look deep into Your eyes (4X)
