Those two creatures that are the same but different in their own way “is a classic example of what looks like intelligences pitted against instinct” (Petrunkevitch 59). The tarantula and the digger (pepsis) are both from the branch called arthropods. Even though the spider is an arachnid and the wasp is an insect they do have some similarities. For example for they are both solitude creatures‚ only when they have to mate they gather among others of their own kind in order for the males

illustrated and each part was properly identified. The most obvious and distinctive features of grasshoppers are their enlarged hind legs and their relatively short‚ thick antennae. The morphology of insects enables the phenomenal success of this class of arthropods. The high rates of speciation‚ short generations‚ and long lineage have caused insects to evolve in many ways‚ resulting in very large variations in morphology.

The Arthropod Story In the entire Animalia Kingdom 83% are Arthropods. Some examples of arthropods are: Spiders‚ scorpions‚ crustaceans‚ and centipedes. We should study Arthropods because there are so many of them that if something happened to remove them from Earth life would not be possible. The crustacean Gammarus wilkitzkii lives on the underside of the Artic pack ice‚ and feeds on other crustaceans. Crabs live up to a mile below the ocean surface in the

Athropods: Arachnids Brief Intro to Arachnids: -Arachnids are a class (Arachnida) of joint-legged invertebrate animals under the Arthropods classification. -Almost all extant arachnids are terrestrial. However‚ some inhabit freshwater environments and‚ with the exception of the pelagic zone‚ marine environments as well. They comprise over 100‚000 named species‚ including spiders‚ scorpions‚ harvestmen‚ ticks‚ mites and Solifugae. (Any water in a sea or lake that is neither close to the bottom

Crab By: Robert Goeren Evolution is the most common ideology debated of all time. Evolution has brought all creatures to their essential environment today. One species that adapted through evolution that has become the largest land-living arthropod in the world is the coconut crab. The coconut crab also known as the robber crab or palm thief is a species of terrestrial hermit crab‚ which is at the upper limit for terrestrial animals. Weighing up to nine pounds it can grow up to three and

In predator-prey relationships‚ prey employ various defense mechanisms against predators in order to increase the chances of survival and reproduction. The same hold true for millipedes. Millipedes‚ members of the class Diplopoda‚ are nocturnal arthropods. Millipedes have segmented bodies with a pair of legs on each segment‚ and range in colors from brown to bright green. They inhabit a variety of forested environments worldwide‚ particularly in dark and damp microclimates underneath rocks and soil

project I had observed the coolest bug balls on earth‚ the roly- poly. They are commonly known as the roly-poly‚ also pill bug‚ and wood lice. Its scientific name is Armadilidum vulgare. It is actually not an insect‚ it is an isopod ( a type of arthropod). It’s genus is Armadilidum‚ it’s Phylum is Arthopoda‚ and Subphylum is Crustacea. I have observed that the exoskeleton is a blue-gray‚ it is an invertebrate‚ it’s mouth‚ antennae and eyes are located on it’s head‚ and it rolls into a perfect sphere
