Spider and Arachnid Life List

My collection of photographs of spiders and other arachnids from my travels.

I was born with an innate fear of spiders, but slowly, I've learned to appreciate their fascinating beauty and diversity. Many species of arachnids require the help of experts to identify in the field. Unlike my other animal pages, I do not attempt to identify most spiders, and certainly appreciate identification help from anybody.

Half-edged Wall Jumping Spider

Menemerus semilimbatus, Photographed in Naoussa, Paros, Greece. Like other jumping spiders, this species, which is distributed around much of the Old World, is characterized by its excellent vision, which it uses for hunting prey. These spiders are agile hunters that actively stalk and pounce on their prey, using silk draglines for safety and as a means of communication.

Kankuamo marquezi

Kankuamo marquezi, Photographed at El Dorado Reserve, Santa Marta Mountains, Magdalena, Colombia. This species, the only in its genus, was named after Colombian author Gabriel Garcia Marquez. This species is known for having urticating hairs: sword-shaped hairs that sting predators, unlike other tarantulas, which can throw their hair.

Heterophrynus elaphus Whip Scorpion

Heterophrynus elaphus, Photographed in Tambopata, Peru. These arachnids are not true spiders or scorpions, but belong to the arachnid class. They are characterized by their flattened bodies, large raptorial pedipalps, and long, whip-like appendages. These arachnids are generally harmless to humans and are not venomous. This species is huge, and it is common for visiting or new naturalists and scientists to be welcomed to the Tambopata area by putting the non-dangerous arachnid on one's face.

Cyclosa Reeves Decoy Spider

This spider, which you can see at the top of this collection of dead insects, is a tiny arachnid that designs fake spiders. This defensive strategy confused predators into attacking the fake spider. Cyclosa Reeves, I photographed this hard-to-find species while traveling to the Tambopata River region, Peru.
