How do compound eyes differ from Human eyes?
a. Compound eyes do not have the ability to focus an image as well as our eyes can
b. Compound eyes do not see colorc. Compound eyes can focus much better
than our eyes because they have SO many lenses to work with. Our eyes only have one lens.
d. Compound eyes see motion much better than our eyes can.
e. Compound eyes produce larger images than our eyes

Sense organs
Have simple organs – statocysts and chemoreceptors
Most also have more complicated organs
Compound eyes are common
> 2000 separate lenses – excellent at detecting colour and movement (better that we can!)
Most can detect UV light

Crustaceans and insects have a good sense of taste
“Taste-buds” located on mouthparts, legs and antenna
Also have hairs that detect motion very well

How do insects move their bodies?
a. They use jet propulsion like octopi or squid. On land they use their spiracles and tracheal tubes to move air instead of water.
b. They have cilia that move them through the grass or the water
c. They swim in the water d. They use muscles to move their
exoskeletons similar to how humans use muscle to move their endoskeletons
e. They have special tissue that moves their exoskeleton from the outside.
Answer: D

Movement Move with
muscles coordinated by NS
Muscles use exoskeleton as we use endoskeleton to move

What is the most common form of reproduction for arthropods?
a. External fertilizationb. Internal fertilizationc. Spore formationd. Egg productione. Internal development

How does an arthropod remove its exoskeleton when it needs to molt?
a. The exoskeleton will crack when the arthropod’s body becomes too large
b. The arthropods have a special internal appendage that can break open the endoskeleton from the inside.
c. The epidermal layer digests the inner exoskeleton layer to re-cycle the chitin
d. The arthropod must find a sharp object to scratch against to weaken the endoskeleton until it break through
Answer: C

Growing Requires MOLTING
Coordinated by hormones
1. The epidermal layer digests the inner exoskeleton layer to re-cycle the chitin
2. Arthropod body excretes a new exoskeleton (inside the old one)
![Page 72: Ch 28 Outline: Arthropods. What animals are in the phylum Arthropods? a.Bumble bees b.Spiders c.Octopus d.Lobsters e.Millepedes Answer all that apply.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d0b5503460f949ddedc/html5/thumbnails/72.jpg)
3. Animal cracks the old exoskeleton and crawls out
4. May eat the old exoskeleton
5. Animal stretches the new exoskeleton to larger size (is done by pumping extra water into the body in aquatic arthropods)
New, larger exoskeleton will then harden

Metamorphosis – A Drastic Change!
Insects demonstrate 2 forms of metamorphosis – complete and incomplete

Incomplete metamorphosis:
a. Insects enter the pupae stage but emerge without making the complete change in
![Page 76: Ch 28 Outline: Arthropods. What animals are in the phylum Arthropods? a.Bumble bees b.Spiders c.Octopus d.Lobsters e.Millepedes Answer all that apply.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d0b5503460f949ddedc/html5/thumbnails/76.jpg)
Incomplete Metamorphosis
grasshoppers, mites, and crustaceans
the egg hatches into an immature animal that looks like the adult but lacks sex organs and other structures such as wings

Complete Metamorphosis Bees, moths,
beetles 4 stages:
1. Eggs
1. Eggs

2. Larvae – hatch from eggs. Look different from adult Grow bigger and molt several times.
Hang upside downIn “j” the day beforeIt turns into a pupa

3. Pupa – the last molt of a larva
Often has a protective coating
Body completely changes and rearranges. Old parts are digested to recycling the materials
just about ready to emerge

4. Adult – emerges from the pupal coccoon.
Even the animals behaviour will be different than the larval stage

Hormones, Molting and Metamorphosis
Molting hormone interacts with other hormones such as “juvenile” hormone
When juvenile hormone is high, the animal continues to molt into the larval stage. Each molt causes the animal to produce less hormone
![Page 82: Ch 28 Outline: Arthropods. What animals are in the phylum Arthropods? a.Bumble bees b.Spiders c.Octopus d.Lobsters e.Millepedes Answer all that apply.](https://reader036.fdocuments.net/reader036/viewer/2022081519/56649d0b5503460f949ddedc/html5/thumbnails/82.jpg)
At a critical lower level of juvenile hormone, the animal will molt into the pupa

When juvenile hormone is completely gone from the system, the pupa molts into the adult

Some plants use chemicals that mimic insect juvenile or molting hormone as a defence mechanism
Insecticides will also do this
