The molting process. Like other spiders, tarantulas have to shed their exoskeleton periodically as they grow, a process called molting. A young tarantula may do this several times a year as a part of the maturation process, while full-grown specimens only molt once a year or less, or sooner, to replace lost limbs or lost urticating hairs.
Molting is a very stressful time for a tarantula. Juveniles molt about every three months while adults molt every year or two. Depending on how much they eat can affect how quickly they molt. As P. Irminia goes into premolt, they will begin fasting, seek moisture, shed their abdomen hairs, and their skin will darken.
Aphonopelma chalcodes, commonly known as the western desert tarantula, desert blonde tarantula, Arizona blonde tarantula or Mexican blonde tarantula, is a species of spider belonging to the family Theraphosidae. It has a limited distribution in the deserts of Arizona and adjacent parts of Mexico but can be very common within this range.
Like all tarantulas, B. hamorii is an arthropod, and must go through a molting process to grow. Molting serves several purposes, such as renewing the tarantula's outer cover (shell) and replacing missing appendages. As tarantulas grow, they regularly molt (shed their skin), on multiple occasions during the year, depending on the tarantula's age ...
The process of moulting in insects begins with the separation of the cuticle from the underlying epidermal cells (apolysis) and ends with the shedding of the old cuticle (ecdysis). In many species it is initiated by an increase in the hormone ecdysone. This hormone causes: apolysis – the separation of the cuticle from the epidermis
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
After molting, the bristles will grow again. Not all urticating hair types are exhibited by each species of tarantula. Type II urticating hairs can be found in the genera Avicularia, Iridopelma and Pachistopelma (subfamily Aviculariinae).
Poecilotheria metallica, also known as the peacock tarantula, [1] is an Old World species of tarantula. It is the only blue species of the genus Poecilotheria.
