PORIFERABy Emily Globe and Leigha MacPherson
WHAT ARE PORIFERA?
A Phylum under the Kingdom Animalia More commonly known as Sea Sponges First evolved over 500 million years ago Considered the most primitive animals
CHARACTERISTICS OF ANIMALIA
Multicellular Eukaryotic Heterotrophic Reproduce sexually and/or
asexually
CHARACTERISTICS OF PORIFERA
Multicellular Eukaryotic Heterotrophic Reproduce sexually and
asexually Feed through filtration Live in aquatic environments
(freshwater and saltwater) No exact symmetry Lack true tissues, organs, and
germ layers High cellular mobilty

LIFE CYCLE OF A SEA SPONGE
Porifera start as free swimming larvae
They anchor themselves on the ocean floor
During adulthood, sperm is released, which can enter a female sponge and fertilize eggs
The larvae are released and the cycle begins again
Sponges can also reproduce asexually by budding
MAINTAINING HOMEOSTASIS
All Porifera are sessile Tiny flagella circulate a current of
water through pores in the sponge This water contains tiny pieces of
food, as well as oxygen Collar cells and amoebocytes
digest food Waste and carbon dioxide is
excreted through the osculum (open end of the sponge)
INTERESTING FACTS Considered to be the very first living animals Porifera are hermaphrodites: they can be both male and
female Act as a home for smaller organisms Inspired the main character of the popular children’s cartoon
SpongeBob SquarePants Porifera skeletons have been used by humans for cleaning
and bathing since the time of the Ancient Greeks
The name Porifera means “bearing pores” in Latin
Aristotle considered sea sponges to be plants The presence of spicules used to be part of the criteria for
classifying organisms as Porifera We now have three classes under the Phylum Porifera:
Hexactinellida, Calcerea, and Demospongaie The class Sclerospongaie was previously used, but is no
longer considered valid
