Porifera, commonly known as sponges, are considered the oldest of the animal phyla. As a sponge, I am able to filter my entire body weight of water in less than a minute using a system of canals, pores, and beating flagella. I provide refuge for other sea creatures and help keep the ocean clean by filtering up to 90% of bacteria from the water. While I am multicellular, I lack tissues but enjoy relaxing in the ocean and occasionally hitching rides on other organisms. I contain toxic chemicals to deter predators and always have a place in the marine ecosystem.

(ANIMALIA)

2. Porifera
Hello, I am a Porifera, that means "pore bearer" in Latin, but my
friends sometimes call me Sponge. We are considered the
oldest of the animal phyla. Like many of my family members I
can filter my entire body weight in water in less than one
minute. I am able to do this using a special system of canals
and pores on my multicellular skin. Water movement is driven
by the beating of flagellae on some of my specialized cells. I
am a nurturing being and am good with children and other
species. I sometimes even provide refuge and protection to
other sea critters.

3. You’ll Be
In My Heart



I am not a picky organism, I can live wherever there is
water.
My beating flagella help water flow through my pores,
supplying me with food oxygen, and a method of waste
removal. Food items are taken into individual cells by
phagocytosis, and digestion occurs within individual cells.
I can regulate the amount of flow through my bodies by the
constricting various openings. The volume of water passing
through my body can be enormous, up to 20,000 times its
volume in a single 24 hour period. In general, I feed by
filtering bacteria from the water that passes through me.
Some sponges trap roughly 90 percent of all bacteria in the
water they filter. I am all about going green and keeping the
ocean clean.

4. All You Need
Is Love
I enjoy organism watching and just generally
relaxing in the ocean.
 I am also known for spontaneously hitching a
ride on a crab or other organism and
traveling the world.

5. Jai Ho!

My relatives and I can proudly boast that we are the first
multicellular organisms. This is reflected in the fact that
we are multicellular but they do not have any tissues, but
hey I am not complaining, a lack of tissues never
stopped me from having a good time.

I contain toxic substances to discourage predators, so if
you are using this match-making website to stalk me BEWARE. The chemicals warn my competition and
other organisms, that I will always have a space in the
marine ecosystem.

6. I Will Follow You
Into the Dark



My body is a loose assemblage of about six different
types of specialized cells that secrete a supporting
skeleton of collagen fibers and mineral spicules (glass or
calcium carbonate) and carry out the processes of
growth, repair, nourishment, and reproduction.
I am the next Hercules, I can protect you against even
the worst predators including mollusks. I burry into their
skin and create a hole for myself and my girlfriends to
sink into for protection.
Though I myself am an omnivore who only eats bacteria
and whatever floats by me, I can introduce anyone who
is interested to my brother the carnivorous exception.
Don’t worry he won’t bite, well usually.

7. Looking for my
Uptown Girl



I am looking for a girl who is okay with a slob, since
I eat, poop, and breathe with every pore in my
beautiful body.
I am available to any single women out there who
are looking for a casual fling, but I am willing to wait
a lifetime for my soul mate in the meantime I can
reproduce asexually.
I need someone who enjoys stopping and smelling
the roses and enjoying the scenery of life; I am a
slow mover and can only travel at the high speed of
4mm a day.

8. 
Classification of porifera:
There are about 5,000 species of sponge, mostly marine and few freshwater
species. In sea they occur up to a depth of 8,500 m and mostly flourish in warm
waters. Size can vary from a few cm to several metres. The body shape is highly
variable.
Class CALCAR
EA
(=CALCISPON
GIAE) Small
marine sponges
with calcareous
spicules.
Class HEXACTINE
LLIDA
(=HYALOSPONGI
AE). Marine glass
sponges with 6-rays
spicules.
Class DEMOSPON
GIAE. Massive
frame sponges with
sponging fibres and
siliceous spicules.
