Materials available in lab:
- Various pieces of bath sponge
- Various preserved demosponges
- Slides of demosponges showing spongin
- Preserved material of Scypha and Grantia
- Slides (ls and xs) of Scypha and Grantia
- Slides (wm and xs) of Leucosolenia
- Dry specimen of Venus's flower basket
Suggested drawings:
- Make a drawing of either the Stinking Vase Sponge or Chalindra showing
the external configuration of a large sponge. Include on that page, drawings
of what spongin material looks like.
- Make a composite drawing of the whole specimen of Scypha/Grantia with
detailed drawings based on the examination of the l.s. and x.s. slides.
- Make a drawing of the arrangement of spicules in Leucosolenia.
- Make a drawing of the Venus's flower basket? Are there crabs/shrimp
inside the sponge? If so, how many? Make a detailed drawing of body wall
of the sponge showing the arrangement of the silicious fibers.
