CLAW MEETS HOP
They will look for similar traits that these two share in their phylum.
Finally, they will look for differences that may be because of class traits.
GRASSHOPPER Pt. 2
HOPPING TO EVOLUTION
2. A grasshopper’s eardrum is on its abdomen, so you could say they hear with their bellies.
3. The fossil record shows that grasshoppers have been around for 200 million years and had evolved before the dinosaurs appeared.
4. Grasshoppers are good at detecting rhythm, but bad at detecting differences in pitch of notes.
5. They make noises by stridulating (rubbing the hind leg against the wing) and crepitating (snapping the wing in flight).
6. The 10,000 or so different species of grasshopper have distinct identifying rhythms.
7. In Japan, grasshoppers are seen as a sign of good luck.
8. Grasshoppers can jump a height of about 25cm and length of a metre.
9. A small cuticle in a grasshopper’s knee acts as a spring and lets it catapult its body into the air.
10. Eating insects is called ‘entomophagy’. Chapulines fundido (grasshopper fondue) consists of crispy fried grasshoppers on a bed of a puree of grasshoppers with shallots, garlic and chilli.
ARTHOPODS Pt. 2: CRAZY CRAYFISH
CRAYFISH RESPIRATORY SYSTEM
Someone who studies crayfish (and some other fish) is called a Hydrogeologist .
There is a species that is blue. It is called a Blue Crayfish. There are also red and white crayfish.
The red crayfish is the most common, the blue is the second most common, and the white crayfish is the least common.
With proper care a crayfish can live two years in captivity.
Over 350 species of the 500 crayfish species of the world live in the United States.
The most common crayfish gets 3-4 inches long, but they can get much bigger in the wild in deep lakes.
There is a crayfish that is called a dwarf crayfish that is really tiny.
