Summary Introduction

To write:

Real-life arthropods cannot become as large as the giant arthropods shown in horror movie.

Introduction:

Arthropod, any member of the phylum Arthropoda, the biggest phylum in the animal kingdom, which consists such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all well known species of animals are members of this phylum. Arthropods are represented in each habitat on Earth and show a huge variation of adaptations. Several kinds live in aquatic environments, and others reside in terrestrial ones; few individuals are even adapted for flight.

Explanation of Solution

There are over 800,000 named species in the Phylum Arthropoda, together the familiar arachnids, crustaceans, and insects, collectively with a host of less familiar critters, like centipedes, millipedes and sea spiders. Arthropods in real life range in length from about 1 millimeter to 4 meters (about 13 feet). They have a segmented body with a tough exoskeleton. They additionally have jointed appendages. The body segments are the head, thorax, and abdomen. Arthropods are used in film to create fear in horror and thriller movies. Arthropods used in films may be animated, sculpted, or otherwise synthesized; however, in lots of cases these films use real creatures. Therefore, we will say that actual life arthropods cannot become as large as the giant arthropods shown in horror movie.

Conclusion

Arthropods contain a tough exoskeleton that cannot stretch and thus, this can restrict or inhibit growth. However, they shed or molt the exoskeleton several times duration their lifespan. All of these reasons affect the size that Arthropods attain. In reality they are not as large as the giant arthropods shown in horror movie.
