The type of sound production that is produced by grasshoppers is:
Stridulation
Identify:StructurePurpose
Fore wingsThey serve as a covering for the hind wings when at rest
The fore wings are borne on the mesothorax
Identify:
Hind wingsNote the wing veins
What is the tracheae?
The air tubes or gas exchange system
Identify:StructurePurpose
SpiraclesThe site of oxygen diffusion (the spiracles open up into the system of tracheal tubules.
These two body parts constitute the respiratory system of the grasshopper.)
Identify:StructurePurpose
Tympanic membraneServe as an organ of hearing
What type of coelom does Romalea have?
Hemocoel
What type of circulation does the grasshopper have?
Open circulation
Identify:StructurePurpose
CropSite of food storage
Note that the esophagus is before the Crop, if something is pinned there, it could be the esophagus
Identify:StructurePurpose
Gastric cecaSecrete digestive enzyme and aid in food absorption
Identify:StructurePurpose
StomachWhere digestion takes place
Identify:StructurePurpose
Malphigian tubulesThese tubules remove wastes and salts from the blood
The Malphigian tubules may also look like #9:

What phylum does this organism belong to?
Nematoda
Which genera did we study that are in the phylum Nematoda?
Turbatrix (the vinegar eel)
Trichinella
Ascaris lumbricoides
Identify:PhylumGenus
NematodaTrichinella
Encysted in the muscle tissue of the pig
Identify:PhylumGenus
Female or male?Does this organism cause a disease? If yes, what is the disease called?
NematodaTrichinella
FemaleYes, trichinosis
Nematodes (AKA round worms) are commonly dioecious and they use a hardened structure known as a spicule during
copulation.
What phylum does organism belong to?What genus does this organism belong to?
EchinodermataAsterias
What are two unique features of the Echinodermata?
Calcareous endoskeletonsWater vascular systems
Their larvae are bilaterally symmetrical, while the adults exhibit radial symmetry
Identify:StructurePupose
MadreporiteThe intake of water into the water vascular system
Located on the aboral surface
