### species:

Dioecious specie
* exhibit sexual dimorphism with females being larger than males.
* have high within population diversity reflecting obligate outcrossing.

Diurnal specie
* Most diurnal species are non-luminescent and use pheromones to find mates.
* are iridescent while nocturnal species are duller.
* depend on daytime light intensity to accomplish foraging and hunting.

Dolphin specie
* All dolphin species have a blowhole.
* Most dolphin species have great vision and they hear well too.
* Some dolphin species gather in enormous groups of several hundreds or thousands.

Dominant specie
* lists the larger plants that are most likely to be seen.
* shift in order from year to year probably in response to timing of recruitment.
* vary between areas and habitat types.

Drosophila specie
* are found all around the world, with more species in the tropical regions
  - prey for many generalist predators such as robber flies
  - small flies, typically pale yellow to reddish brown to black, with red eyes
* vary widely in their reproductive capacity.

Eastern specie
* are also more aggressive in their site-selection.
* tend to extend their ranges by pushing westward, particularly in the North.

Endemic specie
* Many endemic species have a limited georgraphic range, such as a single island.
* Most endemic species are restricted to freshwater habitats, mainly in eastern forested regions.
* are animals and plants that live in only one region of the world.
* are species found no where else
  - that are found only on oceanic islands
* occupy open expanses of water, they like clean and cold water.

Evergreen specie
* Most evergreen species require protection from wind, especially during winter months.
* are the most tolerant of low light levels.
* don t get the same rest period as deciduous species.
* have dark, glossy leaves.

### species:

Exotic specie
* Some exotic species breed and die in the subimaginal stage
  - can exist harmoniously in their new environment
  - establish and grow quickly, crowding out native species
* are animal and plant species that find themselves outside their native habitat
  - dangers on the biodiversity front
  - no threat to the bank swallow
  - often prone to more restrictive laws than non-exotic species
* can be harmful or helpful to the environment they are introduced to
  - become pests and are managed aggressively
  - help an ecosystem by providing a missing link in a failing food chain
  - outcompete, parasitize, and prey upon native species
  - threaten native ecosystems and reduce services that ecosystems provide to humans
* competing for remaining nest sites make nesting even more difficult.
* disrupt the native ecosystem by competing for resources needed by indigenous species.
* have the potential to become invasive when they are released into a new environment.
* thrive on disturbed lands.

### species:

Few specie
* are capable of domestication
  - considered to be cannibals in that they prey on other caterpillar species
  - more social than pigs
  - thought to have been evolved symbiotic and sponging relationships
  - very poisonous and only two, both African tree snakes, are dangerous to humans
* exhibit such a mating system.
* fly at night, but some do.
* live in really putrid media.
* match tilapias in terms of their potential to become the cultured fish of the future.
* reproduce by cloning.

Fungal specie
* Many fungal species are parasitic on plants or animals.
* Some fungal species are known to be infectious to humans and animals
  - grow as unicellular yeasts
* are important to the cycling of nutrients
  - numerous during both mesophilic and thermophilic phases of composting

Herbaceous specie
* Many herbaceous species grow in association with white oak.
* Some herbaceous species are toxic to livestock.
* vary with forest type.

Hermaphroditic specie
* Some hermaphroditic species produce testes and ovaries and can self fertilise.
* can self-fertilize.
