Arthropods | Arthropoda

Arthropods are small invertebrates characterized by an external skeleton, a body having segments each with paired jointed appendages. They are classified under phylum Arthropoda with their bodies being bilaterally symmetrical and also containing cuticles. Most Arthropods use a compound eye as their primary source of information. Additionally, they are a good source of food and also play an essential role in the environment as pollinators, scavengers, and recyclers of nutrients. They are adaptable and are the only animals that are successfully dominating the land, water, and aerial habitats. Unlike other animals that increase continuously on their own, Arthropods have to go through a process called molting when growing.

What is the largest group of arthropods?

The largest group of arthropods are insects, and they can be distinguished from other arthropods through specific characteristics. These characteristics include them having 3 body regions, 3 pairs of legs, as well as a pair of antennae. Most insects also have the ability to fly, which other arthropods lack.

How do arthropods grow?

The arthropods grow through the process of forming new segments near their tail. The growth of an arthropod is very similar to the growth of annelids. Arthropods like mollusks have a tough exoskeleton, but this exoskeleton does not grow along with the rest of the animal and they have to shed their exoskeleton periodically.

Why are arthropods important?

Arthropods are considered because they carry out a different number of roles and tasks. Arthropods can help with pest control or weed control, they also carry an important ecological role due to their large number of species and diversity. Arthropods also serve as food for other species within the food chain.

Goliath Birdeater (Theraphosa blondi)
Scale illustration of an average Goliath Birdeater compared to other spider species

The name Goliath Birdeater (Theraphosa Blondi) comes from its ability to prey on small birds. The spider is native to South America and is the largest spider in terms of body weight. This spider belongs to the family Tarantula and unlike other members of this family, females do not prey on males which often die on maturity. In defense mode, the Goliath Birdeater stridulates or releases hairs harmful to predators or aggressors. Or show large fangs that can pierce human skin. These spiders do not spin webs but use their weaving skills to line their burrows and are a delicacy to communities in South America.

The Goliath Birdeater has an overall legspan length between 8.07”-11.42” (20.5-29 cm). Goliath Birdeaters have a typical body length of 3.54”-5.12” (9-13 cm), body width of 1.57”-2.24” (4-5.7 cm), and body height of 1.57”-2.24” (4-5.7 cm). The common lifespan of the Goliath Birdeater is between 3-6 years for males and 10-20 years for females.

Florida Stone Crab (Menippe mercenaria)
Set of size comparison illustrations of the size of a Florida Stone Crab to other crustaceans

Crabs tend to have females being larger than males, except in unique circumstances like in the case of the Florida Stone Crab (Menippe mercenaria) where males have larger carapace and chelae than females. It is a delicacy caught in the western North Atlantic Ocean. The crab belongs to the family Menippidae revealing a pale brown belly but brownish-red dorsal with gray spots. It shelters near dock piling, rocky areas, oyster reefs, and jetties. The Florida Stone Crab is a nocturnal creature, capable of migrating seasonally, and using self-amputation to district predators or takes advantage of their massive chelipeds that can withstand significant pressure.

The Florida Stone Crab has a carapace length between 3”-3.4” (7.6-8.7 cm), carapace width of 5.1”-5.7” (13-14.5 cm), body height of 2.6”-3” (6.5-7.5 cm), and weight between 3-6 oz (85-170 g). The typical lifespan of the Florida Stone Crab is between 6-8 years.

Mormon Cricket (Anabrus simplex)
Comparison illustration of the size of a Mormon Cricket to other species of insects

The Mormon Cricket (Anabrus simplex) is a large insect that lives throughout western North America in rangelands dominated by sagebrush and forbs. Despite its name the Mormon Cricket is a shieldbacked katydid and not a cricket, and its name references Mormon settlers in Utah who encountered them while pushing westward. The species has a variable coloration with black, brown, red, purple, or green hues. The shield behind the head has colored markings, and the abdomen may be striped. Their diet consists mostly of forbs, but they will eat other insects including other Mormon Crickets.

The Mormon Cricket has an overall body length between .98”-2.44” (25-62 mm), body width of .3”-.75” (7.5-19 mm), and body height of .35”-.85” (9-21.5 mm). The typical lifespan of the Mormon Cricket is between 2-3 months.

Yellow Garden Spider (Argiope aurantia)
Comparison illustration of the size of a Yellow Garden Spider to other species of spiders

Few spiders can build an orderly web like the Yellow Garden Spider (Argiope aurantia) of the family Araneidae. They are also called Corn Spider or Writing Spider, where males die after copulation and may sometimes be eaten by the female. Females bear the striking appearance of distinct yellow and black patterns on their abdomen. They may also have white cephalothorax. Look for it in open sunny fields and tall vegetation in North and Central America. Apart from creating distinct circular-shaped webs flooded with zigzags of silk, it also eats the web at night and rebuilds it in the morning or at daylight.

Male and female Yellow Garden Spiders vary in size. The female Yellow Garden Spider has an overall legspan length between 2”-2.91” (51-74 mm), body length of .75”-1.1” (19-28 mm), body width of .39”-.55” (10-14 mm), and body height of .22”-.32” (5.7-8.2 mm). The male Yellow Garden Spider has an overall legspan length between .55”-.94” (14-24 mm), body length of .2”-.35” (5-9 mm), body width of .1”-.18” (2.5-4.5 mm), and body height of .06”-.1” (1.5-2.6 mm). The common lifespan of the Yellow Garden Spider is between 1-2 years.

Scale illustration of an average Amazonian Giant Centipede compared to other myriapod species

The Amazonian Giant Centipede (Scolopendra gigantea) is a centipede that lives in the tropical and sub-tropical rainforests and tropical dry forests of South America and the Caribbean. As a carnivore, the Amazonian Giant Centipede can overpower and kill many invertebrates like large insects and spiders, and also small vertebrates including small lizards, frogs, and mice. The species is solitary and should be kept alone. There is at least one human death attributed to the Amazonian Giant Centipede’s toxic venom. Like other members of the genus scolopendra, the centipede has 21 or 23 well marked sections with each section having a pair of legs.

The Amazonian Giant Centipede has an overall length between 11”-11.8” (28-30 cm) and width of .91”-1.14” (23-29 mm). The typical lifespan of the Amazonian Giant Centipede is between 8-15 years.
