Pg. 116 RTW: Of the 32 animal phyla, how many do you think are worms?
Objective:
I will be able to cite examples and explain the adaptations to the marine environment of the invertebrate phyla: Annelida.
Agenda:
Annelida notes
Annelida group be ready to present tomorrow!
Homework:
Fish Food Project

3. Phylum: Annelida
Marine Worms

4. Marine Worms Platyhelminthes- flat worms Nemertea- ribbon worms
Simple Marine Worms Phyla:
Complex Marine Worms Phylum
Platyhelminthes- flat worms
Nemertea- ribbon worms
Nematoda- round worms
Annelida
Class Polychaeta- mostly marine worms

5. Characteristics of Marine Worms
Have nephridia (water regulating tubule) as part of the excretory system, a heart, and sometimes jaws.
They show metamerism (division of body in repeating blocks or segments)

6. Special Attributes More than 15,000 species!
Most of the marine worms are in the Class Polychaeta including:
Tubeworms
Bristleworms
Spongeworms
Fireworms
Christmas tree worm spawning
Bobbit Worm

7. Nautilus Live- Tube Worms

9. Pg. 116 RTW: What is one characteristic of Annelida?
Thursday, April 13th
Pg. 116 RTW: What is one characteristic of Annelida?
Objective:
I will be able to cite examples and explain the adaptations to the marine environment of the invertebrate phyla: Echinodermata.
Agenda:
Echinodermata foldable & notes
Echinodermata group be ready to present tomorrow!
Homework:
None 

10. Echinoderm Foldable Examples: Class Asteroidea: sea stars
Subclass Ophiuroidea: brittle stars
Class Echinodea: sea urchin and sand dollars
Class Holothuroidea: sea cucumbers
Class Crinoidea: feather stars, sea lilies

11. Echinoderm Foldable General Characteristics:
(Most) Have a water vascular system for movement.
Tube feet for attachment & locomotion
One-way digestion : separate mouth and anus
Skin covered in bumps
External fertilization
Some have the ability to regenerate

12. Echinoderm Foldable Diagrams: Draw an example of each of the classes.
Reproduction: Sexual and fertilization happens externally.

13. Echinoderms
Phylum Echinodermata

14. Include sea stars, sea urchins, sea cucumbers

15. Have radial symmetry based on 5 parts (similar parts surrounding central axis) Planktonic larvae has bilateral symmetry
Considered to have oral/aboral sides, NOT dorsal/ventral

16. Body Structure Have a water vascular system- water filled canals
Tube feet-muscular extensions of these canals usually end in suckers used for attachment & locomotion

17. Ampullae-muscular sacs that sometimes fill tube feet with water
Madreporite-connects vascular system to outside on aboral (top) surface
Also has gonads & digestive system
No heart, brain or eyes

18. Complete digestive tract- stomach, digestive gland & anus
Endoskeleton-covered by a thin layer of tissue
Surface covered with bumps & spines giving them their name- ”spiny skinned” (echinodermata)

19. Five classes 1)sea stars 2)brittle stars Class: Asteroidea
Subclass:Ophiuroidea

20. 3)sea urchins & sand dollars Class: Echinoidea
4)sea cucumbers
Class: Holothuroidea
3)sea urchins & sand dollars
Class: Echinoidea

21. 5)feather stars & sea lilies
Crinoidea

22. Sea stars (starfish) 5 arms to 50 Most are
predatory- bivalves, snails,
barnacle, etc.

23. Sunflower Star

24. Cushion Star

25. Brittle Stars Arms very long & flexible -tube feet lack suckers
Eat particles of
organic matter
passed from feet to mouth
More species than
any other group of
echinoderms

26. Basket Star (Brittle Star)

27. Brittle Stars

28. Sea Urchins & Sand Dollars
Filter feed on drifting plant/animals
Deposit feeders
that live on bottoms
using tube feet
lined with mucus to
pick up particles

29. Sea Urchins

30. Sand Dollar Alive vs Dead
Sand Dollars

31. Sea Cucumbers Wormlike, lack spines Tube feet around mouth reach
out and pick up
organic material
Escapes by
ejecting digestive
system distracting
predators

32. http://www. youtube. com/watch
Sea Cucumber

33. Feather stars & Sea lilies
5 to 200 arms
due to the
branching
Mucus helps
in catching food
Some attach to
bottom, some crawl
on surfaces in
shallow to deep water

34. Sea Lilies (with Stalks)
Feather
Stars (no
Stalks
Sea Lilies (with Stalks)

35. Biology Sexes are separate in most echinoderms External fertilization
Spawning occurs at once to increase survival

36. Echinoderms can use regeneration to replace missing parts
In some sea stars a severed arm can grow into a complete individual
