Invertebrates

Description
Description

Invertebrates are animals without a vertebral column or backbone. This vast group comprises over 95% of all animal species, including insects, arachnids, mollusks, crustaceans, corals, sponges, and more. They inhabit a myriad of environments, from the deepest oceans to the highest mountains, adapting to an incredible range of habitats. Invertebrates are ancient, with their origins tracing back to the Precambrian period, over 600 million years ago. Over time, they've evolved complex life cycles and forms, showcasing nature's versatility. Their roles are pivotal in ecosystems, involving pollination, decomposition, and serving as key food sources for other animals, thus maintaining ecological balance.

Anatomy
Anatomy

Invertebrates are a diverse group of animals lacking a backbone. This category encompasses insects, arachnids, mollusks, crustaceans, and more. Their body structures vary widely: some have hard exoskeletons like beetles, while others, like jellyfish, are soft-bodied. Movement varies from the fluttering of butterfly wings to the slithering of worms. While invertebrates don't "speak," many communicate through chemical signals, colors, or vibrations. Their senses are adapted to their environments; for instance, spiders have sensitive hairs to detect vibrations, and many insects have compound eyes for detecting movement. Invertebrates are crucial in ecosystems, serving roles from pollinators to decomposers.

Human Interaction
Human Interaction

Humans have a multifaceted relationship with invertebrates, ranging from utilitarian to cultural significance. Agriculturally, we depend on insects like bees for pollination, yet battle pests that threaten crops. Silk, honey, and shellac are examples of valuable products derived from invertebrates. Scientifically, invertebrates are vital study subjects, advancing our understanding of biology and medicine. However, they're often portrayed negatively in pop culture, depicted as villains or monsters in films like "Arachnophobia."

Conservation efforts for invertebrates, like the Monarch Butterfly, are growing due to their ecological importance and declining populations, often spurred by habitat loss and climate change. This complex dynamic underscores their crucial role in our world.

Common Questions
Common Questions
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.

Staghorn Coral (Acropora cervicornis)
Dimensioned comparison drawing of the Staghorn Coral compared to other corals and a person

The Staghorn Coral (Acropora cervicornis) lives close to the surface in warm marine waters. These waters should also have adequate light and oxygen supply. It is one type of coral unique to both marine life and humans in that in areas where it is abundant; it provides a suitable habitat for marine organisms while also protecting shorelines from enormous waves and storms. Staghorn Corals reproduce sexually and asexually and have two kinds of polys and tentacles in multiples of three. These corals may be golden tan or pale color while the tips are white. These corals grow in dense stands with antler-like branches that come out of a central trunk upwards.

The Staghorn Coral has an overall colony diameter between 3.3’- 9.8’ (1-3 m) and typical height of 3’-5’ (.91-1.52 m). The diameters of the individual branches are roughly 1.6”-2.75” (4-7 cm) with branch lengths of 3.3’-6.6’ (1-2 m).

Caribbean Reef Squid (Sepioteuthis sepioidea)
Scale illustration of an average Caribbean Reef Squid compared to other cephalopod species

The Caribbean Reef Squid (Sepioteuthis sepiodea) is a small species of squid that has a torpedo-shaped body and undulating fins. They are 1 of the 6 species of flying squids. The coloring of the Caribbean Reef Squid is made up of a mix of brown and white. Caribbean Reef Squids have the ability to propel themselves out of the water about 6.6 ft (2 m). They are native to the Caribbean Sea and the coast of Florida. Caribbean Reef Squids are able to consume 30% to 60% of their body weight daily in small fish, crabs, and shrimp. Their current population status is not known.

The Caribbean Reef Squid has an overall length between 4.7”-7.9” (12-20 cm) and mantle length of 3.5”-4.7” (9-12 cm). The typical lifespan of the Caribbean Reef Squid is between 1-3 years.

Atlantic Sea Nettle (Chrysaora quinquecirrha)
Measured comparison illustration of the size of a Atlantic Sea Nettle to a typical person and jellyfish

The Atlantic Sea Nettle, known as Chrysaora quinquecirrha, is a relatively small jellyfish of various colors found along the Atlantic coast of the United States. When compared to the Pacific Sea Nettle, the Atlantic Sea Nettle is smaller. The Atlantic Sea Nettle, though small, is capable of delivering a potent sting. The Atlantic Sea Nettle’s tentacles are covered in coiled stinging filaments ready to release once they are touched. This sting, while not inherently dangerous to humans, is able to kill small prey and deter predators. The Atlantic Sea Nettle is carnivorous and feeds on small marine critters and uses its powerful sting to stun and kill its food.

Atlantic Sea Nettles have a bell width between 5”-9.84” (12.7-25 cm), bell height of 2.36”-4.33” (6-11 cm), and overall length of 17.7”-35” (45-89 cm). The typical lifespan of the Atlantic Sea Nettle is 6-18 months.

Brown Widow (Latrodectus geometricus)
Comparison drawing of the Brown Widow compared to other spiders

There are two ways of separating the Brown Widow (Latrodectus geometricus) of the family Theridiidae from similar relatives–the Black Widow. First, the former is smaller and lighter, revealing a dark brown or black body with shades of grey and secondly with its egg sac resembling a sandspur. Also called House Button Spider, Brown Button Spider, Geometric Button Spider, Brown Black Widow, and Grey Widow, this spider is cosmopolitan in tropical areas, preferring safe habitats such as homes, woody vegetation, and idle equipment. The Brown Widow also spots an hourglass-shaped marking on their abdomen. They are thought to have origins in Africa and can unleash a nonvenomous bite if threatened.

Male and female Brown Widows vary in size. The female Brown Widow has an overall legspan length between 2.05”-2.72” (52-69 mm), body length of .47”-.63” (12-16 mm), body width of .22”-.3” (5.5-7.5 mm), and body height of .28”-.37” (7-9.5 mm). The male Brown Widow has an overall legspan length between .98”-1.38” (25-35 mm), body length of .24”-.31” (6-8 mm), body width of .12”-.16” (3-4 mm), and body height of .12”-.18” (3-4.5 mm). The common lifespan of the Brown Widow is between 1-3 years.

Red Rock Crab (Grapsus grapsus)
Comparison drawing of the Red Rock Crab compared to other crustaceans

It may be more delicious than the Dungeness Crab, however, the Red Rock Crab (Cancer productus) is less meaty. If you are a sport or commercial fisherman, you can locate it on or near harder substrates like rock and pilings in the eastern Pacific coast in North America. But be warned that the Red Rock Crab is very agile, hence hard to catch. The Red Rock Crab fits in the family Cancridae with teeth set between the eyes, both of which have equal size and shape. Juveniles can assume different colors but adults are brick-red, possessing large distinctive pincers with black tips and a lack of projection or serration on their claws.

The Red Rock Crab has a carapace length between 1.8”-3.1” (4.6-8 cm), carapace width of 2”-3.4” (5-8.7 cm), body height of .8”-1.4” (2-3.5 cm), and weight between .8-2 lb (.36-.91 kg). The typical lifespan of the Red Rock Crab is between 8-12 years.
