HEPTATHELA Meaning and
Definition
-
Heptathela refers to a genus of primitive spiders that belong to the family Heptathelidae. These spiders are commonly known as "trapdoor spiders" due to their distinctive burrowing behavior. The term "heptathela" comes from the combination of the Greek words "hepta" meaning seven and "thela" meaning nipple. This name is derived from the seven pairs of nipples typically found on the ventral surface of the abdomen in females of this genus.
Heptathela spiders are primarily found in East Asia, specifically in regions of China, Japan, and the Korean Peninsula. They are known for their unique ability to construct burrows with intricate trapdoors made of soil, silk, and plant material. These trapdoors serve as a means of protection by allowing the spider to hide from potential predators and prey. The size and complexity of the trapdoors vary among species and can range from simple lids to more intricate structures with multiple layers.
These spiders are nocturnal predators that primarily feed on small invertebrates such as insects and other arachnids. They rely on their excellent vision and sensitive leg hairs to detect prey approaching their burrows. Heptathela spiders are female-dominant, with females being larger and more long-lived than males. Mating occurs within the female's burrow, after which the female lays eggs in an egg sac. Once hatched, the spiderlings remain in the maternal burrow until they reach maturity.
Heptathela spiders are of scientific interest due to their ancient lineage and unique behaviors. They offer valuable insights into the evolution and diversification of arachnids and their interactions with their environment.
Etymology of HEPTATHELA
The word "heptathela" has its etymology rooted in Greek. It is composed of two Greek words: "hepta" meaning "seven" and "thelē" meaning "nipple" or "teat". Thus, "heptathela" literally translates to "seven teats". This term is used to refer to a particular genus of spiders known as Heptathela, which includes species found in China, Japan, and Southeast Asia. The name probably originates from the spider's spinning apparatus, which may resemble seven small teat-like structures.
