1 You reach into a tank and poke a brittle star fish. It responds by quickly moving under a nearby rock and curling into a ball. The brittle star responded to your touch because of which of the following receptors:

A Photoreceptor

B Chemoreceptor

C Statocyst

D Thigmoreceptor

2 You reach your arm into a tank containing a sea urchin & move your hand close to the animal. While your hand is several inches away from the urchin, it begins to wave its spines erratically. The urchin detected the your presence via:

A Chemreceptor

B Thigmoreceptor

C Statocyst

D Photoreceptor

3 Which of the following must be included is a sea star fragment for an entire organism to regenerate:

A A majority of the arms

B A majority of the water vascular system

C A fragment of the central disc

D A fragment of the stomach

4 Echinoderms have which type of skeleton:

A endoskeleton

B exoskeleton

C hydrostatic skeleton

D axial skeleton

Page 6: Unit #5 Quiz #1, 2013-2014

5 Which of the following echinoderms have primitive gills:

A Sea Urchin

B Sea Star

C Sand Dollar

D Sea Cucumber

Page 7: Unit #5 Quiz #1, 2013-2014

6 Brittle stars and sea stars differ in their modes of movement in that:

A Brittle stars use hydraulics within their tube feet to suction onto a surface and hold there for a long period of time, while sea stars drag themselves across a surface with tube feet that resemble spines

B Sea stars use hydraulics within their tube feet to suction onto a surface and hold there for along period of time, while brittle stars drag themselves across a surface with tube feet that resemble spines

C Brittle stars use their tube feet to slide across a surface similar to the motion of a hover craft

D Sea stars can push water out of their mouth to lift themselves off of a surface and push themselves onto another, whereas s brittle star must climb up the same object

8 Sea stars have ocelli:

A located at the very center of the organism on the dorsal side

B located at the terminal end of each arm

C located at the very center of the organism on the ventral side
