An Opening on the Outlandish

Arthropods (Arthropoda) is a phylum characterized by invertebrates with exoskeletons. They belong to the kingdom Animalia. The name literally means "jointed foot". Arthropods have open circulatory systems, are not hermaphroditic, have two antennae, have segmented abdomens, and have eyes. The Arthropoda phylum is one of the most diverse, with creatures that swim, crawl, and fly.

Objective Objective

Students will learn about the internal and external anatomy of arthropods, with a special emphasis on the integumentary system. Students will also learn about the arthropod's ecological role, focusing on crickets and crayfish.

Revolutionary Evolutionary Relationships

Crayfish belong to the class Crustacea, and crickets belong to the class Hexapoda. These two classes have the most in common out of all the classes in Arthropods.

Helpful Human Impact

Arthropods is the biggest phylum in the domain Animalia. Because of this, it has a huge importance. Arthropods, especially the class Hexapoda, are the major pollinators. Arthropods are also food for other animals and keep smaller species' population under control.

Crickets are major decomposers, which keeps the outdoors clean. Crickets help with pollination, which is necessary for a major percentage of our food. Crickets also eat seedlings from invasive species, keeping those invasive species levels low. Crickets are also used as pets, and in some cases are used in cricket fights.

Crayfish keep water clean by scavenging dead material in streams, ponds, and other water bodies. Crayfish also keep algae amounts down and are food for many animals. Crayfish are also used as pets.

Feasibly Fun Facts

  • Scorpions can give live births after the eggs hatch inside the mother.
  • The Arthropod phylum is the biggest phylum in the domain Animalia.
  • There's an average of 30 insect parts per 100 grams of peanut butter.
  • Crickets have ears behind their legs.
  • Only female crickets have a long ovipositor on their end.
  • Chirping sounds are different so females can tell which crickets are their species.
  • There are more than 330 species of crayfish in southeastern United States alone.
  • Crickets that are taped to a fan blade right before a fight have almost a 100% chance of winning.
  • Insects are eaten in almost all cultures except most European, Islamic, and Hindi cultures, and many cultures also eat crustaceans like crab and lobster.

The Interesting Integumentary System

Arthropods have a tough exoskeleton as their skin. This has benefits and consequences. An exoskeleton is stronger than an endoskeleton, and is better at preventing water loss. However, as an arthropod grows, it will have to molt and get rid of the old exoskeleton. Exoskeletons are also less flexible.
