Sponges Porifera By: Shayna Dicker, Hannah Duminske, John Mark Miller, and Isaac Bianco
Most live in salt water Some live in fresh water rivers, lakes, and streams Where do they live?
Babies swim through the water with flagella Some adults get moved by being washed away by waves Adults never move; they are sessile How do they move?
Has many body openings called pores & one central cavity Number & Names of body openings
Asymmetrical Type of symmetry
Saltwater sponges - red, orange, yellow, or blue Freshwater sponges - dull brown or green Body
Extract food from water, pulled through its pores Diet consists of bacteria, protists, algae, and other materials How and what they eat?
Extract oxygen from the water through pores How they get oxygen
Release sperm into water Sperm floats until they are drawn into another sponge Will also use asexual reproduction (regeneration) Reproduction
Sponges Phylum: Porifera. Why are Sponges in the Animal Kingdom? While sponges can’t move (sessile) most of the time, they are considered heterotrophs.
Sponges - Origin of Sponges Fossil evidence shows that sponges appeared on Earth about 600 million years ago. Many scientists have concluded that sponges.
The Sponges. General Characteristics Porifera means “full of holes” Sponges are the simplest of animals Live in both freshwater and saltwater.
The Wonderful World of Sponges. Sponge Structure ● The bodies of many sponges are only 2 layers thick ● Their bodies are covered in many small pores (holes)
Comparing Invertebrates. Metazoans Also known as Kingdom Animalia –Multi-cellular –Develop from embryos –Divided into two groups based on the presence.

Sponges Chapter 9 Section3.
Phylum Porifera Sponges. PHYLUM PORIFERA Sponges oldest of all animals few specialized cells sessile – can’t move.
What is a sponge? Sponges are asymmetrical aquatic animals that have a variety of colors, shapes, and sizes.
CNIDARIA Domain:Eukaryota Kingdom:Animalia Phylum:Cnidaria.
Aquatic Ecosystems. Freshwater Ecosystems Streams Rivers Ponds and lakes.
Invertebrates An invertebrate is a member of the Animal Kingdom without a backbone.
Invertebrate Notes. Sponges- Porifera “Pore Bearer” Show examples Evolutionary sideline - alone. Simple multicellular animals lacking true tissues.
Invertebrate Phylum: (Sponges) PORIFERA.
Animal Phyla: Porifera & Cnidaria
Ch. 35 Porifera Invertebrates Animals without a backbone 97% of all species Simplest is sponge.
SPONGES PHYLUM PORIFERA.
The simplest animal Invertebrates No symmetry Live in water all over the world Depend on water for food, oxygen, and reproduction.
Introduction to Invertebrates 5 th Grade. Invertebrates Animals without backbones can have bilateral symmetry, radial symmetry and no symmetry Are part.
