### animal | arthropod | insect | whitefly:

Giant whitefly
* Giant whiteflies exhibit a strong tendency to feed in groups.
* produces copious amounts of wax.

Greenhouse whitefly
* Greenhouse whiteflies are insects
  - worldwide pests of greenhouse-grown ornamentals and vegetables
* can transmit viruses.
* common pest of house plants and greenhouse plants.

Wingless insect
* Most wingless insects have length
  - possess abdominal appendages
* Some wingless insects eat wallpaper
  - undergo metamorphosis

Instar
* are arthropods
  - important because they allow the caterpillar to grow
* are the stages between each molt
  - during the life cycle between molts
* is an arthropod
* reach an end once the mantid has developed wings.

### animal | arthropod | instar:

Early instar
* differ considerably in appearance from the later instars.
* feed on the lower leaf surfaces
  - within the cambial tissues
* skeletonize the underside of soybean leaves, leaving the upper leaf surfaces intact.

### animal | arthropod:

Krill
* Most krill eat phytoplankton
  - find in oceans
* Most krill have exoskeletons
  - hard exoskeletons
* Most krill live in deep water
* Most krill survive for long periods
* Some krill eat algas
  - animals
  - antarctic algas
  - small animals
  - zooplankton
  - feed on algas
  - have bellies
  - live for years
* Some krill live in oceans
  - southern oceans
  - make up diets
  - survive winter
* are crustaceans.
* compete for algae with gelatinous creatures called salps.
* constitute the next biggest source of protein.
* consume phytoplankton.
* employ two types of spawning mechanism.
* exist in large numbers and are an integral part of the aquatic food chain.
* feed baleen whales.
* feed on plankton floating near the ocean's surface
  - the green algae that coats the ceiling of sea ice that floats atop the Southern Ocean
  - nourishment
* have ability
  - survival
* includes brains
  - carapaces
  - cell membranes
  - cells
  - corpi
  - cytoplasm
  - heads
  - nuclei
  - pincers
  - plasma membranes
  - sections
  - shells
  - skulls
  - thoraxes
  - vacuoles
* live at least two and possibly up to five years.
* live in areas usually affected only every few days by the wobbling ozone hole
  - on the undersides of ice sheets, where they find refuge and algae as food
* move backwards by using their tails.
* provide food.
* reach maturity after two to three years.
* reproduce during springs.
* rise and fall in the water column depending on the time of day.
* start their lives in the summertime when females lay eggs near the surface.
* takes place in all oceans of the world but mainly in Antarctic Ocean.
* tend to rise to the surface at night to feed, and retreat to deeper waters during the day.
* travel in swarms so dense they can be seen from space.

### animal | arthropod | krill:

Antarctic krill
* are considered the greatest under-tapped biological resource in the ocean today
  - found in the seas surrounding the peninsula and the rest of the continent
  - one of the most abundant and successful animal species on Earth
  - very popular in the world
* can scrape off the green lawn of ice-algae from the underside of the pack ice.
* forms dense concentrations, called swarms, during the Antarctic summer.
* graze the algae along the underside of sea ice.
* is one of the most abundant and successful animal species on the planet
  - the key species for marine food web chain in the Antarctic waters

Northern krill
* are tiny crustaceans that float in large swarms.
* emerge from the furcilia stage as fully developed adults.
* go through four larval stages after hatching.
* occur across the Atlantic from the Mediterranean Sea northward.
