Q

What is the presence of spines called?

A

Ossicles they are emerged from bony plates?

22
Q

Where are ossicles located?

A

They lie underneath the skin which creates a dermal skeleton

23
Q

Echinoderms are mostly what shape?

A

Radically symmetrical

24
Q

What is the most distinctive feature of the Echinoderm?

A

The water vascular system

25
Q

What is the water vascular system made up of?

A

It’s made up of internal canals and self appendages called tube feet

26
Q

Why is the circulatory system greatly reduced?

A

Because it uses the coelomic fluid through the tube feet to pass through nutrients and gasses

27
Q

What are the five classes of Phylum Echinodermata?

A

Class Crinoidea- Sea Lillie’s
Class Asteroidea- Starfish
Class Holothuroidea- Sea Cucumber
Class Ophuroidea- Brittle Star
Class Echinoidea- Sea Urchin, Sand Dollars

28
Q

When looking at the oral surface is that the top or the bottom of the Sea Star?

A

Bottom

29
Q

What is the aboral side top or bottom?

A

Top

30
Q

What are the spine extensions called?

A

ossicles

31
Q

What does the calcareous plates form?

A

The dermal skeleton

32
Q

What can you see on the oral surface of the arms of a starfish? What are they used for?

A

Finger like tube feet and are used for locomotion

33
Q

What is ampulla?

A

Ampulla is on each foot internally on top

34
Q

What is the button shaped thing called on top of the starfish what is its function?

A

It’s called a madreporite and it allows the water to travel through into the inter canals of the water vascular system because they’re connected

35
Q

What are the eight characteristics of Echinodermata?

A
  • Calcitic (calcium carbonate + proteins) endoskeleton made of ossicles
    -Water vascular system
  • ossicles, are connected by ligaments composed of collagen allows animals to maintain a posture without any muscular effort
  • Pentaradial body organization in adults- origins of 5 fold symmetry are not understood
  • Bilateral embryonic coelom
    -Dieoecious, marine, external fertilization
    -Decentralized nervous system, no brain
    -open circulatory system- cilia moves water through each arm
36
Q

What type of feeders are Crinoidea?

A

Filter feeders

37
Q

What is the name of Crinoidea appendages called?

A

Cirri

38
Q

What type of digestive enzymes do Asteroideas have?

A

Secrete digestive enzymes that absorb the digested coral

39
Q

Water Vascular system

A

Label the parts of the system go to good notes to do so.

40
Q

How does water vascular system work for Asteroideas?

A

It starts with the water entering the madreporite which passes through the stone canal, then the ring canal, which the water is then distributed to the radial canals, the water is then pressure into the ampullae into the tube feet

41
Q

What type of skeletal system does Asteroideas have?

A

They have an internal skeletal system

42
Q

What is the Echinoidea mouth structure called?

A

Aristotles lantern

43
Q

How many teeth does the Aristotles lantern have?

A

5 teeth

44
Q

How many teeth does the Aristotles lantern have?

A

5 teeth

45
Q

Label the sea urchins madreporite and tube foot

A

Go onto good notes to do so.

46
Q

Where do Holothuroideas live?

A

On the sea floor

47
Q

How do Holothuroideas obtain oxygen from water?

A

Through a pair of respiratory trees

48
Q

What are the Ophuroidea called besides brittle stars?

A

Serpent stars

49
Q

How do you Serpent Stars move?

A

They use their 5 long arms used for locomotion

50
Q

How many shield plates do Serpent stars have?

A

5 mouth shield plates

51
Q

How many jaws does serpent stars have?

A

They have 5 jaws

52
Q

What does serpent stars have on each jaw?

A

5 papillae
