The blue lacerta lives up to 6000 years old, making it an incredibly ancient creature. During that time, it grows, changes body shape, shrinks, and behaves differently.
0 - 500 years-
These years are the hatchling years. A hatchling is about 35cm newly hatched, and grows up to five metres at about five hundred years of age. A hatchling has rather large webbed feet for this age, a large tail, a smaller body, and a medium sized head. These are all features which differ between individuals, and these features are grown out by the time the blue lacerta reaches maturity.
500 - 1000 years-
These years are the years where the blue lacerta is growing out of the hatchling stage, and are the years of 'pre - teen' to 'teenager' stage. A blue lacerta at this age has smaller webbed feet, a slightly longer body, slightly longer and more muscular legs and a medium sized head. However it still has a larger paddle-shaped tail. At this age, blue lacertas would be about 10 - 15 metres in length, depending on individuality.
1000 - 1500 years+ -
These years are considered as the 'late teen' to the adulthood stage. In these years, a blue lacerta's body is reasonably in proportion, with small feet, shorter legs, a medium sized tail, and a medium sized head. Depending on individuality, the finnage can be either long or short. The blue lacerta would have grown about 18 - 20 (20 at the absolute most) metres if a female, and about 19 - 20 metres if a male. Males will also be reasonably bulkier in muscle than females.
5500 - 6000 years-
These years are about the last years of a blue lacerta's life. At this stage, a blue lacerta may have slightly shrunken in size, and may be fairly fragile and crippled, compared to ones of a younger generation. Blue lacertas may also face arthritis in some joints, and may become thinner. Muscle tone will begin to fade, and they will be weaker than they previously were before. Blue lacertas at this age rarely stay twenty metres in length, in fact they will probably shrink gradually throughout a few centuries. A common age for elders is about seventeen metres long, some reaching eighteen, and some may shrink down to fifteen or sixteen. It depends on the age and size of the blue lacerta in both previous years and current years.
Albinism in blue lacertas is quite rare. Albino blue lacertas rarely survive in the wild, as they are easily visible, and they do not have great visibility. They have pinkish-red irises, with a normal black slit for a pupil, and have creamy coloured scales, with hints of pink and white. Markings can be a slight pink or creamy yellow in colour, or can be cream. The first albino blue lacerta sighted was a mature female, by the name of Timide (Pheney (c) ), and has been watched and cared for by an Aboriginal tribe.
Albinism does not occur often within the gene pool, and chances of albinos breeding with blues are rare. However, it still occurs. When an albino blue lacerta breeds with a normal blue, there can be a number of different outcomes.
Blue with white points/markings
This is uncommon, and is almost never seen. This mutation is where a 100% blue lacerta breeds with an albino blue lacerta. It has the appearance of a normal blue lacerta with either white 'points' (white/cream muzzle, feet, tail tip.. etc) or a blue lacerta with white/cream markings. Eyes can either be golden or red, it depends on how strong the albino gene is in the parent.
White with blue points/markings
This is also uncommon, and occurs in the same way as the 'blue and white points' occurs. However, this mutation occurs when the albino gene is stronger than the dominant blue gene is, in the 'blue and white points' mutation. The blue lacerta will have a cream/white body, with blue points, or blue markings. Eye colour is usually red, with slightly stronger visibility than a full albino.
This gene is rare, and occurs mostly by chance. To achieve this mutation, a parent must be a 100% blue lacerta, and a 100% albino blue lacerta. But even then, there is a one in ten chance that the hatchling could turn out differently. The blue lacerta will have patches and splotches of blue and cream, sometimes with markings, sometimes with none. The eyes can be either golden or red, again, the eye pigment is by chance.
What happens when a mutation breeds with another mutation? Well, to start off, this would be extremely rare, as to begin with, there are not many albino blue lacertas in the world anyway. But if it so happened that a mutation was to breed with a mutation, then the offspring could either turn out just like one of it's parents, or it would turn out completely different. Because the 'blue' is the dominant gene, then if a 'pied' for example was to breed with a 'blue and white points', then the offspring would mostly likely become a normal blue lacerta. However, it may have red pigmented eyes, and, it will still have the albino gene within it, so it would not be a '100% blue lacerta'.
However, it really depends on how much of the albino gene and the dominant blue gene the parents have, to be able to make an accurate decision.
