Q:

How do arthropods reproduce?

A:

Quick Answer

Arthropods reproduce by transferring sperm from the male to a female by way of sealed packets called spermatophores, according to the Encyclopedia Britannica. With few exceptions, arthropods are sexed as male or female, and both sexes have gonads, or sex organs, directly connected to ducts on the ventral surface of their trunks. The exact location of these ducts varies considerably amongst arthropod species.

During reproduction, sperm is not diluted with any other medium, according to Encyclopedia Britannica. In most arthropods, the spermatophore is left on the ground once reproduction occurs. After a nuptial dance, the male assists the female in positioning herself over the spermatophore to take it into the genital opening.

Fertilization in most arthropods results in the female laying eggs. In some arthropods, such as the scorpion, the eggs hatch inside the mother. She gives birth to live young and cares for her babies for an extended period, according to Wikipedia. Arthropods are all born at different stages of development ranging from fully formed miniature adults to grubs or caterpillars. When arthropods are born as grubs or caterpillars, they undergo metamorphosis, a period of inactivity where larval tissues are broken down and re-used to help build the adult body.
