Study Notes
Porifera (Sponges)
- Sponges are filter feeders, drawing water through their bodies to filter out particles
- Sponges lack tissues
- Sponge bodies are diploblastic, with 2 layers separated by mesohyl
- Sponge cells include choanocytes (flagellated collar cells) and amoebocytes (make spicules or skeletal fibers)
Spongilla
- Spongilla is a type of sponge
- It has a rhagon sponge skeleton
- It lives in freshwater
Grantia Larvae
- Images showing Grantia larvae (microscopic views)
Grantia Cross Section
- Shows the spongocoel and incurrent canals
- Spicules are present
Grantia Long Section
- Diagram identifying the osculum, spongocoel, and spicules
Sponge Spicules
- Sponges spicules can be made from silica, glass, or calcium carbonate.
Leucosolenia
- Shows Leucosolenia with osculum and spicules (microscopic)
Euspongia
- Includes spicules, mesohyl, and radial canals
Examples of Dried Sponges
- Images of different types of dried sponges
Phylum Cnidaria
- "Cnidaria" translates to "nettle"
- Cnidarians have two forms: polyp (attached) and medusa (free-swimming)
- Radial symmetry, tentacles, a single opening for food and waste, and nematocysts (stinging threads).
- Body plan is gastrovascular
- Portuguese Man-of-War (specific example)
Hydra Ingesting Food
- Hydra, a predominantly polyp form, is a hydrozoan (specific group of Cnidarians)
- Hydra’s body plan is a polyp
- Hydra ingests food using its tentacles.
