there are very few left
if you know what the salamander eats
This depends on the subspecies of salamander. Because you haven't specified, some general foods are commercial salamander diet, crickets, earthworms (not wild collected). There are many other good foods, but I encourage you to do your own research on your specific salamander.
Giant kangaroos no longer exist.
5000
There are 1,600 pandas left in the wild or somewhere around there.....
No, the Chinese government is protecting te giant panda, and it's illegal to shoot a giant panda in China. Also, there's 3,000 giant pandas in tbe wild, and like 180 in captivity. Also, the giant panda population is rising.
The lifespan of a giant panda in the wild is about 30 years.
there are 1600 in the wild left is that amazing or what:-)
almost all salamanders have 24 chromosomes. I don't believe it is any different for the "spotted"- most likely wild type- creature you have described.
there are about 1,200 in the wild and 200 in captivity
Nearly extinct in the wild, many are now being trained in South Africa to learn to hunt on their own, and will be introduced into the wild in Chinese reserves.
The best habitat for that Salamander is the stream you took it from. It is a wild creature. Please return it to where it came from.
