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.

Domestic Silk Moth (Bombyx mori)
Comparison drawing of the Domestic Silk Moth compared to other insects

The Domestic Silk Moth (Bombyx mori) is a moth related to the wild silk moth. The silkworm is the caterpillar of the Silk Moth. While the species is native to China, it has been introduced throughout the world, and with complete domestication, it is no longer found in the wild. The wings are cream with dark veins that extend to the margins, and they have reduced or absent mouthparts. The Domestic Silk Moth is unable to fly, but the adult male can perform a flutter dance, a mating ritual that is induced by secretion of a pheromone by the female.

The Domestic Silk Moth has a total wingspan in the range of 1.18”-1.97” (30-50 mm). The body of the Domestic Silk Moth has an overall length between .67”-1.14” (17-29 mm), body width of .24”-.39” (6-10 mm), and body height of .2”-.35” (5-9 mm). The typical lifespan of the Domestic Silk Moth is between 6-8 weeks.

Hammerhead Flatworm (Bipalium kewense)
Comparison illustration of the size of a Hammerhead Flatworm to other worms

The Hammerhead Flatworm (Bipalium) is a predatory land planarian named after the distinctive shape of their head region. As their native habitat were regions of Southeast Asia, they like environments that are hot and humid, so they do well in greenhouses and tropical and subtropical areas. They like to be out of the sun under leaf litter, rocks and logs, and shrubs. The Hammerhead Flatworm has a half-moon shaped head; it is usually light colored with one to five dark dorsal stripes and a dark collar. They are a known predator of earthworms, but they may feed on other organisms.

The Hammerhead Flatworm has an overall length between 7.87”-15.75” (20-40 cm) and diameter of .12”-.2” (3-5 mm).

Knobbed Whelk (Busycon carica)
Comparison drawing of the Knobbed Whelk compared to other gastropods

The Knobbed Whelk (Busycon carica) is a large predatory sea snail species native to the North Atlantic coast of North America, from Cape Cod, Massachusetts to northern Florida. The shell is thick and strong with six clockwise coils, and the surface is sculpted with fine striations with a ring of knob-like projections that protrude from the widest part of the coil. The color can vary from ivory to pale gray, and the large aperture is orange. On shallow water Knobbed Whelks prey on oysters, clams, and other marine bivalves.

Knobbed Whelks have a length between 5”-9” (12.7-22.9 cm), width from 3.15”-5.91” (8-15 cm), height of 3.15”-5.51” (8-14 cm), and weight in the range of .88-1.98 lb (.4-.9 kg). The typical lifespan of the Knobbed Whelk is 10-15 years.

Green Lynx Spider (Peucetia viridans)
Comparison illustration of the size of a Green Lynx Spider to other species of spiders

If you are looking for a spider for pest management, the Green Lynx Spider (Peuceta viridans) is your best choice. However, note that the spider is a threat to pollinating agents. A bright-green color and the ability to change color from green to pale yellow make it fit it's arboreal background. It is the largest spider in the family Oxyopidae whose venom is harmful to small prey but not to humans. The Green Lynx Spider is native to North America and is nicknamed after its body color. It is separated from other spiders in the same family by distinctive hexagonal eye arrangements and several black spots and prominent spines on its legs.

Male and female Green Lynx Spiders vary in size. The female Green Lynx Spider has an overall legspan length between 1.1”-2.05” (28-52 mm), body length of .47”-.87” (12-22 mm), body width of .12”-.22” (3-5.5 mm), and body height of .13”-.24” (3.2-6 mm). The male Green Lynx Spider has an overall legspan length between 1.02”-1.18” (26-30 mm), body length of .43”-.51” (11-13 mm), body width of .11”-.13” (2.8-3.3 mm), and body height of .12”-.14” (3-3.5 mm). The common lifespan of the Green Lynx Spider is 1 year.

Black Sea Nettle Jellyfish (Chrysaora achlyos)
Measured comparison illustration of the size of a Black Sea Nettle Jellyfish to a typical person and jellyfish

The Black Sea Nettle, known scientifically as Chrysaora achlyos, regarded as a giant jelly has a large purplish bell with long, lacy arms that function as mouths. In addition to its mouth-arms, the Black Sea Nettle has tentacles that are even longer than its mouth-arms. The Black Sea Nettle is usually found in the warm waters of the Pacific ocean from Monterey Bay to Baja California. Overall, Black Sea Nettle sightings are rare, but when they are seen they usually appear in large swarms coinciding with red seas and abundance of zooplankton.

Black Sea Nettle Jellyfish have a bell width between 16”-36” (40.6-91.4 cm), bell height of 8.3”-18.9” (21-48 cm), and overall length of 44”-104” (112-264 cm). The typical lifespan of the Black Sea Nettle Jellyfish is 6-12 months.
