types:
genotype
a group of organisms sharing a specific genetic constitution
clade
a group of biological taxa or species that share features inherited from a common ancestor
colony
a group of organisms of the same type living or growing together
division
(biology) a group of organisms forming a subdivision of a larger category
generation

division Eubacteria
one-celled monerans having simple cells with rigid walls and (in motile types) flagella
Cyanophyta,
division Cyanophyta
prokaryotic organisms sometimes considered a class or phylum or subkingdom; coextensive with the Cyanophyceae: cyanobacteria (blue-green algae)
Chrysophyta,
division Chrysophyta
mostly freshwater eukaryotic algae having the chlorophyll masked by brown or yellow pigment; yellow-green and golden-brown algae and diatoms: Xanthophyceae, Chrysophyceae, Bacillariophyceae; some classification systems superseded or subsumed by Heterokontophyta
Chlorophyta,
division Chlorophyta
large division of chiefly freshwater eukaryotic algae that possess chlorophyll a and b, store food as starch, and cellulose cell walls; classes Chlorophyceae, Ulvophyceae, and Charophyceae; obviously ancestral to land plants
Cynodontia,
division Cynodontia
a division of the order Therapsida from the Triassic period comprising small carnivorous tetrapod reptiles often with mammal-like teeth
Adapid,
Adapid group
extinct small mostly diurnal lower primates that fed on leaves and fruit; abundant in North America and Europe 30 to 50 million years ago; their descendents probably include the lemurs; some authorities consider them ancestral to anthropoids but others consider them only cousins
Omomyid,
Omomyid group
extinct tiny nocturnal lower primates that fed on fruit and insects; abundant in North America and Europe 30 to 50 million years ago; probably gave rise to the tarsiers; some authorities consider them ancestral to anthropoids but others consider them only cousins
Pisces
a group of vertebrates comprising both cartilaginous and bony fishes and sometimes including the jawless vertebrates; not used technically
kingdom
the second highest taxonomic group into which organisms are grouped; one of five biological categories: Monera or Protoctista or Plantae or Fungi or Animalia
subkingdom
(biology) a taxonomic group comprising a major division of a kingdom
biotype
organisms sharing a specified genotype or the genotype (or peculiarities) so shared
team
two or more draft animals that work together to pull something
brood
the young of an animal cared for at one time
herd

herd
a group of wild mammals of one species that remain together: antelope or elephants or seals or whales or zebra
pack
a group of hunting animals
pod
a group of aquatic mammals
caste
in some social insects (such as ants) a physically distinct individual or group of individuals specialized to perform certain functions in the colony
colony
(microbiology) a group of organisms grown from a single parent cell
variety

tribe
(biology) a taxonomic category between a genus and a subfamily
genus
(biology) taxonomic group containing one or more species
subgenus
(biology) taxonomic group between a genus and a species
monotype
(biology) a taxonomic group with a single member (a single species or genus)
species
(biology) taxonomic group whose members can interbreed
race,
subspecies
(biology) a taxonomic group that is a division of a species; usually arises as a consequence of geographical isolation within a species
type
(biology) the taxonomic group whose characteristics are used to define the next higher taxon
drove
a group of animals (a herd or flock) moving together
form division
an artificial taxonomic category for organisms of which the true relationships are obscure
gen X,
generation X
the generation following the baby boom (especially Americans and Canadians born in the 1960s and 1970s)
litter
the offspring at one birth of a multiparous mammal
Phycomycetes,
Phycomycetes group
a large and probably unnatural group of fungi and funguslike organisms comprising the Mastigomycota (including the Oomycetes) and Zygomycota subdivisions of the division Eumycota; a category not used in all systems
domain
(biology) the taxonomic category above the kingdom; the three domains are Eukarya, Archaea, and Bacteria
