Invertebrates

Invertebrates are all species of animals without a backbone or spine, which includes arthropods (insects, crustaceans, etc.), mollusks (bivalves, snails, squid, and octopus, etc.), annelids (worms, etc.), and cnidarians (corals, anemones, jellyfish, etc.). The earliest fossils appear to be invertebrates which have been dated back to 665 million years ago. Invertebrates are the largest class of animals, comprising 97% of the animal kingdom with 1.25 million species discovered, but millions still to be discovered. A key to the large quantity of invertebrates is their ability to reproduce quickly and abundantly, with some species’ members producing both egg and sperm, and some species laying eggs that do not require fertilization. Invertebrates are comprised of a wide range of species, all the way from microscopic mites to the giant squid.

How do invertebrates protect their soft bodies?

Invertebrates can effectively protect their soft bodies through an outer hard casing that is referred to as the exoskeleton. Invertebrates like spiders, crustaceans, and insects have their exoskeletons made through sections of jointed legs. Others like mollusks like snails and clams have a hard shell in which they can hide when danger is present.

What is the difference between an invertebrate and a vertebrate?

The difference between an invertebrate and a vertebrate is that invertebrates have no backbones while vertebrates have a developed internal skeleton with cartilage and bones as well as a developed brain that is protected by a skull. Vertebrates also cannot make their food, while invertebrates make their food.

Why are invertebrates important?

Invertebrates are important because like bees they help with pollination, as well as help clear and clean up the environment. Invertebrates are also important because they are soil aerators and creators as they help grow food crops. They also provide eco-system balance and serve as food for other species within the food chain.

Common Periwinkle (Littorina littorea)
Measured comparison illustration of the size of a Common Periwinkle to other gastropods

The Common Periwinkle (Littorina littorea) is a small edible sea snail and a marine gastropod mollusk that has gills and an operculum. They are native to the northeastern rocky shores, and they were introduced to the northwestern Atlantic Ocean. The shell of the Common Periwinkle is broadly ovate, thick, and sharply pointed except when eroded. It has six to seven whorls with some fine thread and wrinkles. The coloration can be gray to gray-brown with dark spiral bands, and the inside of the shell is chocolate brown. The species is omnivorous and primarily grazes on algae, but it will also eat small invertebrates like barnacle larvae.

Common Periwinkles have a length between .63”-1.5” (1.6-3.8 cm), width from .43”-1.06” (1.1-2.7 cm), and height of .43”-1.06” (1.1-2.7 cm). The typical lifespan of the Common Periwinkle is 4-10 years.

German Cockroach (Blattella germanica)
Comparison illustration of the size of a German Cockroach to other species of insects

The German Cockroach (Blattella germanica) is a small cockroach that varies from tan to almost black. They have two dark, roughly parallel streaks on the pronotum, from behind the head to the base of the wings. While German Cockroaches have wings, they can barely fly, but they may glide if disturbed. They are widely considered domestic pests. As omnivorous scavengers, they are attracted to meats, starches, sugars, and fatty foods. If there is a shortage of food, they will eat household items like soap, glue, and toothpaste, and in famine conditions, they turn cannibalistic.

The German Cockroach has an overall body length between .43”-.63” (11-16 mm), body width of .16”-.24” (4-6 mm), and body height of .12”-.18” (3-4.5 mm). The typical lifespan of the German Cockroach is between 3-9 months.

Brown Recluse Spider (Loxosceles reclusa)
Comparison illustration of the size of a Brown Recluse Spider to other species of spiders

Brown recluse spiders are a venomous spider located in North America. Brown recluse spiders only live by themselves as their name suggest, they are shy. Related to the Black Widow, if bitten by a brown recluse spider you’d need to be hospitalized. Only growing under an inch in diameter, this light brown spider can be seen with markings on their dorsal side. Brown recluse spiders only have 6 eyes compared to other spiders who have 8. They often look for dead insects because of their less eyes they cannot respond quick enough to hunt live food.

The Brown Recluse Spider has an overall legspan length between .83”-1.46” (21-37 mm). Brown Recluse Spiders have a typical body length of .28”-.47” (7-12 mm), body width of .08”-.16” (2-4 mm), and body height of .09”-.16” (2.2-4 mm). The common lifespan of the Brown Recluse Spider is between 2-4 years.

Yellow Tube Sponge (Aplysina fistularis)
Scale illustration of an average Yellow Tube Sponge compared to other sponge species and a person

You can identify a Yellow Tube Sponge (Aplysina fistularis) by its one or more tube-like yellowish or sometimes orange-brown structures. Its color depends on the depth it exists in. The bottom of the tubes are closed, but the tops are open, providing suitable habitat for invertebrates. The tubes can’t move since they are attached to the reef's surface. These sponges lack tissue, unlike other sponges with a glass-like skeleton structure. It reproduces both sexually and asexually. The Yellow tube sponge mostly inhabits the coral reefs of the Caribbean, especially in areas with strong currents.

The Yellow Tube Sponge has an overall cluster diameter between 11.8”-39.4” (30-100 cm) and height of 19.7”-47.2” (50-120 cm). The typical diameters of the individual tubes are in the range of 1.2”-5.9” (3-15 cm).

Black Swallowtail (Papilio polyxenes)
Comparison illustration of the size of a Black Swallowtail to other species of insects

The Black Swallowtail (Papilio polyxenes) is a butterfly widely distributed throughout much of North America, and it is the state butterfly of Oklahoma and New Jersey. It is usually found in open areas like fields, parks, marshes, or deserts, and tropical or temperate habitats are preferred. The adult female butterfly is typically larger than the male. The upper wing is black with two rows of yellow spots, and the female Black Swallowtail has a prominent blue area between the two rows. Both sexes have a red spot with a black bullseye on the inner hind margin of the hindwings and a single yellow spot on the front edge.

The Black Swallowtail has a total wingspan in the range of 2.64”-3.5” (67-89 mm). The body of the Black Swallowtail has an overall length between .79”-1.1” (20-28 mm), body width of .13”-.18” (3.3-4.6 mm), and body height of .18”-.22” (4.5-5.5 mm). The typical lifespan of the Black Swallowtail is between 2-3 months.
