Invertebrates

Front 1

4 characteristics of cnidarians.

Back 1

Dimorphism

Radial symmetry

Diploblastic

Sting

Front 2

_______ sponges appear to be larger versions of ascanoids, still having just a single osculum. However, the body wall is generally thicker and more complex with incurrent canals rather than simple pores.

Back 2

Sycanoid

Front 3

_______ sponges are the most complex in design in that not all the chambers are flagellated. These sponges are the best adapted to increase sponge size.

Back 3

Leucanoid

Front 4

_______ sponges have the simplest type of organization. Small and tube-shaped, water enters the sponge through dermal pores and flows into the atrium.

Back 4

Ascanoid

Front 5

How are intestinal platyhelmintheses protected from harsh digestive juices?

Back 5

Using teguments, they are able absorb nutrients and block out digestive fluids.

Front 6

Where does mature female schiztosome live and why?

Back 6

Inside a groove in the male because otherwise finding a mate would be difficult.

Front 7

Lives mostly in marine environments

Turbellaria

Front 8

Main body mass is composed of proglottids

Parasitic flukes of various vertebrates, maybe endoparasites or ectoparasites

Cestoda

Front 12

Mostly carnivores, feeding on smaller invertebrates

Back 12

Turbellaria

Front 13

Hermaphroditic, but do not self fertilize

Turbellaria
Cestoda

Front 14

Totally dependent on host for nutrition, lack digestive track

Back 14

Cestoda

Front 15

Snail is first intermediary host, then fish, then final host

Back 15

Trematoda

Front 16

Usually swim or crawl by cilliary propulsion, sometimes by waves of muscle contraction
