Collect the following data:•
Salt Water Tanks Only:
• DO - Phosphate
• Turbidity - Salinity
• Nitrate - Calcium
• Nitrite - Water Hardness
• Ammonia
• pH
• temperature
Make sure to clean out any excess food from your filter and gravel/sand. Scrub off the inside of the glass & clean the outside with Windex once you are finished.
Phylum Porifera
I. General Information
• Kingdom : Animalia• Phylum : Porifera• Porifera = “pore bearer”
Pink lumpy sponge
Yellow barrel sponge
I. General Information
Size range – 1 cm to2 meters in diameter
Giant Barrel sponges
II. Body Structure A. Ostia – pores – many, water IN
B. Oscula – large opening(s), one or few, water OUT
osculum
II. Body Structure
C. Choanocytes – collar cells;
have flagella D. Amoebocytes – transport food
to layer of cells not on the surface
II. Body StructureE. Spicules – “skeleton” hard
splinter-like; made of calcium
carbonate (CaCO3)
or silica (Si)
F. Spongin – flexible protein
II. Body StructureF. Spongin – flexible protein
III. Level of organization
A. CellularB. EukaryoticC. No tissues
Japanese Deep Sea Sponge
IV. Symmetry
A. Some asymetrical
B. Some radial
V. Habitat
Aquatic - A. Marine and
B. Fresh-water
Purple Rope sponge
Fresh-water Sponge
VI. Feeding• Heterotrophic• Filter feeders• Food trapped
by choanocytes• Intracellular
digestion (within the cell)
• No digestive tract
G
F
E
D
A
BC
VI. Feeding
– Water & food goes in via poroctye– Choanocytes trap food in spongocoel– Amoebocytes carry food to inner layer
of cells– Water out osculum
VII. Respiration
- via diffusion
VIII. Internal transport
• via diffusion
IX. Response
• NONE • No Nervous System• No cephalization
Pipe organ sponge
X. Locomotion1) Free-
swimming larvae using cilia
2) Adults are non-mobile
XI. Reproduction
1. Asexual a. budding b. gemmules
formed in stress
conditions
XI. Reproduction
2. Sexuala. Most hermaphrodites
(both sexes in same organism) - egg & sperm produced
- cross fertilization - egg + sperm
free-swimming larvae
XI. Reproduction
2. Sexual:Some sponges are unisexualThey produce either egg, OR sperm
Sponge releasing sperm
XI. Reproduction
XII. Ecological Roles
A. Habitat for other aquatic animals
B. Food for some
XII. Ecological Roles
C. Home use: bathing, cleaning, home improvement, other
XII. Ecological Roles
XII. Ecological RolesD. Medical research• Sponges do not get cancer Why not?• Maybe we can use what keeps them
from getting cancer to treat humans.• Compounds from sponges have been
found to fight malaria and tuberculosis
Azure Vase Sponge
Giant Barrel Sponge
White Cryptic Sponge
Elephant Ear Sponge
Stove pipe sponge
Yellow Vase Sponges
Yellow Barrel Sponge
Red Branch Sponge
In a group of 2:1) What are the functions of both the large and small
holes in a sponge?
2) What do sponges filter from the water?
3) You are scuba diving in a coral reef and see a pretty Red Branch Sponge. You reach out and snap off one of the branches. What would be the response from the sponge and why?
4) What type of symbiotic relationship(s) will a sponge have with other organisms?
5) How is a natural sponge different than a synthetic sponge? What purposes would each serve for humans and why (Examples: showering, cleaning tile, washing your car)
