200
what does "Arthropod" mean
jointed foot
200
What do decapods use to breath?
gills
200
two mouth parts on a spider and their functions
pedipalps to grab prey, chelicerae (fangs) to inject toxin into prey
200
Animals that eat insects (name 3)

200
The structure that supports an echinoderm's body and gives it it's bumpy texture
Endoskeleton
300
What was the first species of Arthropod?
Trillobite
300
how does haemolymph differs from mammalian blood
It contains copper instead of iron
300
What kind of toxins do a black widow and a brown recluse have (different toxins)
black widow-neurotoxin, brown recluse-haemolyphic toxin
300
Insect sensory organs
compound eyes, ears, sensory hairs, chemical receptors
300
What most echinoderms use to move or capture food
Tube feet
400
What are 3 advantages of an exoskeleton?
flexible chitin can form many shapes, provides support for muscle attachment, and protection from predators
400
How does the carapace form?
Calcium carbonate bonds with chiltin produced by the exoskeleton to form a hard protective plate.
400
What kind of digestion does a spider have?
external
400
Describe complete metamorphosis
egg, larva, pupae, adult
400
The five groups of echinoderms
Sea stars, brittle stars, sea urchins, sea cucumbers, sea lillies and feather stars
500
what are 3 disadvantages of an exoskeleton/
Molting is dangerous, exoskeleton can only support so much weight so there are size limitations, can only get enough oxygen to support small bodies
500
What are crustaceans classified as biramous?
They have branching appendages
500
How does a spider produce it's web?
The silk (protien) producing organ on the abdomen is called a spinneret. It contains glands full of tubules that emit liquid silk when pressure is applied to them. The silk is spun into fibers as hardens immediately when exposed to the air.
500
How do social insects communicate (2 ways)
Pheromones and movement (dances)
500
name 6 parts of the water-vascular system
Madreporite, stone canal, ring canal, radial canal, ampulla, tube feet
