26
What are some common things in Phylum Mollusca?
``` Snails Slugs Oysters Clams Octopuses Squids ```
27
Phylum Mollusca Growth? Symmetry? Mouth and anus?
- Bilateral - Continuous growth - Coelomates - 3/4 are gastropods - Visceral mass - Mantle - Produce hard shell - Foot to move around - Separate mouth and anus
28
Visceral mass
In molluscs Houses complex organs
29
Mantle
In molluscs Tissue that protect visceral mass and can produce a hard shell
30
What phylum is Class Gastropoda in?
Phylum Mollusca
31
What kinds of things do Class Gastropoda include?
Snails | Slugs
32
Class gastropods Facts about snails and slugs
-Continuos growth -Coelomates -3/4 of mulluscs are gastropods Torsion Snail-shell Slug-soft shell or no shell
33
Torsion What class does it refer to?
Anus up by their head Class Gastropoda
34
What kinds of things do class Bilvalvia include?
Clams Oysters Mussels Scallops
35
Class Bivalvia
- Enclosed in hard shells - Shell divided into two halves - 2 shells can come together - Complex organs - Suspension Feeders
36
What things are found in Class Cephalodopa?
Octopus Squid Nautilus
37
Octopus
Class Cephalodopa Totally reduced mantle
38
Squid
Class Cephalodopa Slightly reduced mantle
39
Nautilus
Class Cephalopoda Mantle
40
Class Cephalopoda
- Complex eyes | - Foot is modified into arms
41
What is an interesting fact about Phylum Mollusca?
Most documented extinction
42
What is the common name for Phylum Roundworms?
Phylum Nematoda
43
What is an example of a virus or parasite of a round worm?
Trichinella which can infect humans and cause swelling around eyes if thy eat undercooked bear meat
44
What is another type of worm in Phylum Nematoda besides roundworms?
Hookworms
45
Phylum Nematoda Growth? Symmetry?
- Bilateral symmetry - Grow by molting - Cylindrical - Longitudinal segments - Mostly parasites
46
Molting
Grow in stages and have to shed their exoskeleton in order to grow again
47
Old Friend's Hypothesis
Different places with different worms can treat autoimmune deficiencies
48
Phylum Arthopoda Growth? Symmetry?
- Bilateral symmetry - Biggest Phylum - Grow by molting - Hard exoskeleton - Segmented body - Jointed appendages for locomotion and feeding
49
General characteristic of Arthopods?
Like army knife
50
Class Archnida
Have 8 legs
51
Class Insecta
- Have 6 legs - Many have wings - Wings are separate from legs
52
What are some things found in Class Insecta?
Butterfly's Walking stick Beetles
53
Subphylum Crustacea
-Highly specialized branched appendages
54
What are some things in Sub Phylum Crustacea?
Crabs Lobster Copepods Barnacle
55
What Phylum is Sub phylum Crustacea in?
Phylum Arthopoda
56
Protostome Examples?
Embryo development mode where mouth develops first from blastopore Molluscs Annelids
57
Deuterostome Examples?
Embryo development mode where anus is develops first from blastopore Echinoderms Chordates
58
What things to Phylum Echinoderms include?
Urchins Sea cucumbers Starfish Sand Dollars
59
Phylum Echinodermata Growth? Symmetry?
- Young have bilateral symmetry - Adults have radial symmetry - Very slow or sessile - Not invertebrates - Have exoskeleton that gives them structure - Water vascular system
60
Water vascular system
In Echinoderms Allow them to draw water in and then spit it out to move and feed
61
What things evolved from Phylum Chordata?
Humans and animals
62
What kind of symmetry do Chordates have?
Bilateral symmetry
63
What are two variations of Cnidarians body plan?

64
Polyp
Sessile variant of cnidarian body plan
65
What are some examples of the polyp form?
Corrals
66
Medusa
