Gila-monster


The gilamonster Heloderma suspectum are divided into 2 subspecies, Heloderma suspectum suspectum and Heloderma suspectum cinctum.

According to the last revision of the species, published in 2010, the two subspecies are now degradated to local morphs.

The reason why I provide only limited information on my website about Gila-monsters, their biology and the keeping and breeding of them.

Is that many good publications on this subject are available.

The following books, which I have on my bookshelves, are highly recommended to those who would like to go into Gila-monster.
