Describe the limits of the range. For migratory species describe which parts of the range this species occupies for which parts of the year. Indicate both native and introduced ranges.

Use the world map of geographic ranges to help you find the appropriate world regions.

Indicate both native and introduced ranges by checking the appropriate keywords.

In the text box describe the habitat types that this species occupies, including the elevational (terrestrial) or depth (aquatic) ranges, and any other information on habitat requirements.

Select all habitat checkboxes that apply to this species. At least one of the broad region categories should be selected (polar, temperate, or tropical) and at least one of the broad habitat type categories should be selected (terrestrial, saltwater or marine, or freshwater).

You should then be able to select a more specific type of habitat from the terrestrial, aquatic, or other categories. For example, two-toed sloths would have "tropical", "terrestrial", and "rainforest" selected. Use the Description of Terrestrial and Aquatic Biomes to see a definition of each of the habitat keywords. If the species is migratory, describe all habitats that it regularly occupies.

Use the text box to describe this species. Describe its size, appearance, shape, color, and anything else that is notable. Has geographic or seasonal variation been reported? If there are described sub-species, how do the sub-species differ? Are there polymorphisms? How do young animals differ from adults? Be sure to include a description of the characteristics that distinguish this species from other, closely related, species.

Describe the development and life cycle of this species. How does it progress from newly fertilized egg, through intermediate stages, and to the adult form? Does this involve metamorphosis? How is sex determined? Does your species have indeterminate growth?

Try to be as complete as possible in filling out this information and checking all keywords that apply to these animals. If you do not know whether these animals breed year round or seasonally, or if they are polygynous or promiscuous, then continue to try to find this information or at least an indication that this information is not known. Use the checkboxes that appear below a text box as a guide to what kinds of information should be included in that text box.

In this section describe the mating system and mating behavior of this species. Include information on finding, attracting, and defending mates, and on how mating behaviors affect social structure.

Use the text box to describe the reproductive cycle of this species. Be certain that you are reporting all of the important information relevant to reproduction. In the case of a mammal, this would include season of breeding, number of offspring per breeding season, gestation period, when weaning occurs, and age at sexual maturity. It might also include a description of any peculiarities of the system or anything that is notable or interesting. Examples might include descriptions of delayed implantation or fertilization, induced or spontaneous ovulation, or, in the case of hoofed mammals, whether the young are "followers" or "hiders."

Describe how frequently, or at what intervals, individuals of this species breed. For example: "Wood frogs breed once yearly", or: "White-footed mice breed every 3 to 4 weeks during the warmer months and less frequently during winter".

Indicate the time of year (span of months, for instance) in which breeding occurs. This should be the time when copulation and nesting occurs, and does not necessarily include pair formation (that can go in 'Mating Behavior...').

Indicate the time of year (span of months, for instance) in which fertilization occurs, and, if appropriate, spawning. This does not extend to the time of hatching or birth (that's Gestation or Time to Hatching), and does not necessarily include pair formation (that goes in 'Mating Behavior...').

Indicate the time of year (span of months, for instance) in which fertilization occurs, and, if appropriate, spawning and/or nesting. This does not necessarily include pair formation (that goes in 'Mating Behavior...').

Indicate the time of year (span of months, for instance) in which fertilization occurs, and, if appropriate, spawning and/or nesting. This does not necessarily include pair formation (that goes in 'Mating Behavior...').

Indicate the time of year (span of months usually) in which mating occurs. This should be the time when copulation occurs, not pair formation (which should be in 'Mating Systems'), and should not include the time when births occur (please describe that information in the 'General Behavior' text box).

Indicate the time of year (span of months, for instance) in which fertilization and egg-laying occurs. This does not extend to the time of hatching (that's Gestation or Time to Hatching), and does not necessarily include pair formation (that goes in 'Mating Behavior...').

Indicate the time of year (span of months, for instance) in which copulation and egg-laying or births occur. Include period of incubation or nest-guarding, if appropriate.

Indicate the time of year (span of weeks or months, for instance) in which courtship, mating and oviposition occurs.

Indicate the time of year (span of weeks or months, for instance) in which courtship, mating and oviposition occurs.

Indicate the time of year (span of weeks or months, for instance) in which courtship, mating or gamete exchange, and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which courtship, mating or gamete release, and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which courtship, mating or gamete release, and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which mating or gamete release, and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which copulation or gamete release and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which, copulation or gamete release and egg-laying or births occur.

Indicate the time of year (span of weeks or months, for instance) in which asexual reproduction, gamete release, and/or mating and egg-laying occurs.

Indicate the time of year (span of weeks or months, for instance) in which asexual reproduction, gamete release, and/or mating and egg-laying occurs.

Indicate the time of year (span of weeks or months, for instance) in which asexual reproduction, gamete release, and/or mating and egg-laying occurs.

Indicate the time of year (span of weeks or months, for instance) in which asexual reproduction, gamete release, and/or mating and egg-laying occurs.

Indicate the time of year (span of weeks or months, for instance) in which asexual reproduction, gamete release, and/or mating and egg-laying occurs.
