Reproduction
The Grammostola rosea has been bred in captivity for years either for research purposes or for trade and Gurley, R (n.d) states that the females profit from a ‘cooling period’ of a couple of months proceeding to the introduction of a male for mating. Once a male has reached sexual maturity he will create a sperm web before he is introduced to the female’s terrarium. He will eventually approach the female’s burrow with caution, tapping and vibrating his legs to attract her out of her shelter. At the opportune moment the male will lunge himself forward and using his hooks he will hold the female's chelicerae, pushing his mate into a vertical position giving him access to the female’s epigyne (external genitalia). The male will insert one (or even both left and right) pedipalp into the female's epigyne and inject the fertilizing fluid. Gurley, R (n.d) continues that in the weeks following fertilization, the female produces a large egg sac (usually containing around 500 spiderlings).

Famous quotes containing the word reproduction:
“An original is a creation
motivated by desire.
Any reproduction of an original
is motivated by necessity ...
It is marvelous that we are
the only species that creates
gratuitous forms.
To create is divine, to reproduce
is human.”
—Man Ray (1890–1976)
“The atmosphere parents wish to create when talking with children about birth and reproduction is warm, honest, and reassuring, one that tells children they are free to ask questions as often as they need to, and you will answer them as lovingly as you know how.”
—Joanna Cole (20th century)
“As the twentieth century ends, commerce and culture are coming closer together. The distinction between life and art has been eroded by fifty years of enhanced communications, ever-improving reproduction technologies and increasing wealth.”
