Spiders have long been noted as classic examples of sexual behavior among arachnids, including extreme sexual dimorphism in some groups, and behavioral adaptations to diverse mating patterns. In recent decades, studies on the biology of Neotropical spiders have offered novel information on processes ...
The class Mammalia is worldwide in distribution. It has been said that mammals have a wider distribution and are more adaptable than any other single class of animals, with the exception of certain less-complex forms such asarachnidsandinsects. This versatility in exploitingEarthis attributed in ...
A majority of arachnids, however, are terrestrial organisms where they mostly live as predators of smaller insects.* The name Arachnida comes from the Greek word aráchnē that means spider. Here, it is also worth noting that spiders represent the majority of arachnids....

Scorpions are arachnids in the orderScorpiones. Scorpions haveeight legs, and can be differentiated from other arachnids by theirpedipalps, which take the form of largepincers, and by their extended tails, which are equipped with avenomous stinger. ...
They are members of the group Ecdysozoa, which also includes insects, arachnids, and crustaceans. These animals are all able to shed their cuticles. Nematodes are ubiquitous, which means that they can be found everywhere on earth in different environmental niches. They can be found in soil, ...
These creatures range in size from microscopic to the length of a football field. Mollusks, worms, insects, crustaceans, marine invertebrates, and arachnids are common groupings for invertebrates. Humans come across invertebrates all the time. Read Invertebrates | Definition, Types & Examples Lesson ...
they come out of hiding during the night rather than bask in the sunlight. The scariest part is how sneaky and illusive bark scorpions can be, creeping into homes to take cover from the summer heat or to hibernate from the winter cold. These arachnids are proficient climbers, too, findi...
the appearance of primitive plants, trees, and shrub-like forests provided new habitats for arthropods. The first tetrapods to appear were amphibians (e.g.Ichthyostega). The land continued to be dominated by arthropods, such as arachnids and wingless insects. However, another major mass extinction...
