All data is technically the copyright property of Blue Fang and/or Microsoft Games, how ever some of the following data was collected by accessing and interpreting the coding of Zoo Tycoon 2 by members of Zoo Tycoon Unleashed Forum, thus much thanks should and must be extended to them for all their hard work and generosity. We (the creators of this specific list and webmasters of this site) do not consider the data we collected to fall under our own copyright privileges and it is hard to separate which is our work and which is that of others as the document has been created organically since early 2006. We did, how ever, put a lot of hard work into the database, as did others who’s work has been incorporated into it, and thus it is only polite and courteous to give credit accordingly if publishing this document elsewhere and at least give a mention and appropriate links to the online locations you collected data, other than your own, from (in this case both this site and the Zoo Tycoon Unleashed Forum).

Life spans and maturation periods are not true statistical minimums but are in fact approximate lower end of what could be considered the normal range. Recent additional information provided by PsychicZookeeper and others who first accessed the coding about the process involved in determining what was then believed to be the absolute minimum age, along with additional findings of Papa Panda and Reka has revealed that this belief was based upon a simplified explanation from the Blue Fang representative at the time about how it is determined when an animal is to die and extensive in game testing by numerous individuals.

We now know that life span works like an hour glass, as in that for each day of game play some of the sand falls from the top glass to the bottom and when the sands run out there is then a periodic random probability that the animal will die (1 in 4 for death and 1 in 2 for maturation). The amount of sand that passes from the top bulb to the bottom is NOT fixed (only the size of the hour glass for a specific species is fixed) but within a set range thus the members of a colony of the same species will ‘age’ at a varying rate determined by this random element.

When collating our own data thru extensive in game testing and game play over a period of 6 months, then after that incorporating the data from the Zoo Tycoon Unleashed Forum we never increased a time period if our findings were lower but always reduced the time periods if anyone had listed a shorter time frame and have always continued to re-assess and alter the dates in such a manner as additional data has become available be it from the lists of others or from our own findings during testing and game play. As such it should be unlikely that animals die before these time frames (other than any already in place at the start of a campaign as in some cases they may not be new animals but been set at already being a few months old), it is how ever statistical possible that on extremely rare occasions an animal may die earlier (mathematically the life span can be up to around 25% shorter).

Minimum space requirements are fixed figures within the games coding, how ever in order to reduce the risk of errors creeping into this list we only ever increased the figures from what we initially calculated through in game testing if we came across any contradictory data, never decreased them, on the basis that it is better to be a square or two too big for the first animal and/or each additional than to be even a fraction of a square too small.
