Invertebrates are animals that lack a backbone, and as a result, they have more complex nervous systems than vertebrates. This makes invertebrates some of the most diverse and interesting animals on Earth, and it’s this diversity that interests us here at HowToGeek.
In this blog post, we will explore four main types of invertebrates: cephalopods (e.g. squid, octopus), arthropods (insects and crustaceans), myriapods (millipedes and centipedes), and chelicerates (arachnids). We’ll also explore their unique characteristics and how they can help us understand the biochemistry of life.

Arthropods
Invertebrates are animals without a backbone. They include crustaceans, mollusks, and arthropods, which include insects, spiders, and centipedes. Arthropods have a head with a pair of eyes and a pair of antennae. Most have jointed appendages along their body that give them the ability to move around.
Crustaceans
Crustaceans are marine invertebrates that have a hard exoskeleton. They include crabs, lobsters, and shrimp. Most crustaceans are hermaphrodites, meaning they have both male and female reproductive organs. Crustaceans can move around by using their appendages to pull themselves along or by swimming with their tails sticking out of the water.
Mollusks
Mollusks are aquatic invertebrates that have an outer shell. They include clams, oysters, and squid. Mollusks are hermaphrodites and can reproduce through asexual means as well as through sexual reproduction. Mollusks use their tentacles to move around in the water and their shells to protect them from predators and environmental conditions.
Arthropods
Arthropods are the largest group of invertebrates. They include insects, spiders, and centipedes. Arthropods have a head with a pair of eyes and a pair of antennae. Most arthropods have jointed appendages along their body that give them the ability to move around.
Insects
Insects are the most common group of arthropods. Insects have a head with a pair of antennae and six legs. They can move around by using their appendages to push themselves forward or pull themselves along. Insects feed on plants and animals and can be a major nuisance in homes.
Spider
Spider is the only arachnid class that has eight legs. Spider is the only invertebrate class that has an exoskeleton. Spider has a head with eight eyes and a mouth that it uses to catch prey. Spider has a venom that it uses to kill prey.Some arthropods, like spiders, have venom glands in their heads that they use to
Crustaceans
Crustaceans are a group of invertebrates that includes crabs, shrimp, and lobster. Most crustaceans have a hard exoskeleton that they use to defend themselves and attach to surfaces. Crustaceans can also move around by using their legs and antennae.
Mollusks
Mollusks are a group of aquatic invertebrates that have an outer shell. They include clams, oysters, and squid. Mollusks are hermaphrodites and can reproduce through asexual means as well as through sexual reproduction. Mollusks use their tentacles to move around in the water and their shells to protect them from predators and environmental conditions.

Arthropods are the largest group of invertebrates. They include insects, spiders, and centipedes. Arthropods have a head with a pair of eyes and a pair of antennae. Most arthropods have jointed appendages along their body that give them the ability to move around.Some arthropods, like spiders, have venom glands in their heads that they use to inject poison into their prey. Some arthropods, like spiders, have venom glands in their heads that they use to inject poison into prey
Mollusks
Invertebrates are the largest and most diverse group of animals on Earth. They include mollusks, arthropods, and other invertebrates. The category includes creatures like squid, cuttlefish, crabs, and spiders.
Mollusks are one of the most diverse groups of invertebrates. They come in a wide range of shapes and sizes, from tiny gastropods to giant clams. Mollusks have a soft body that is covered in a protective shell or mantle. Many mollusks are carnivores or omnivores, feeding on small prey items or plant matter. Some mollusks, such as snails and slugs, can cause damage by eating plant roots or damaging crops.
Arthropods make up the second-largest group of invertebrates. Arthropods have a segmented body with jointed limbs that they use to move around. Arthropods include insects, spiders, crustaceans (like crabs and shrimp), and millipedes. Arthropods vary greatly in size and shape; some are very large, like beetles and cockroaches, while others are small enough to fit on the tip of your finger, like fleas.
Invertebrates are a diverse and important group of animals. They include mollusks, arthropods, and other invertebrates. The category includes creatures like squid, cuttlefish, crabs, and spiders.
Other invertebrates include worms, centipedes, ticks, lice, ants, bees (and wasps), dragonflies and butterflies. Invertebrates play an important role in Earth’s ecology by feeding on plants or
Hexapods
There are a vast array of invertebrates, each with its own unique set of features and capabilities. Some common invertebrate groups include hexapods, arthropods, myriapods, and crustaceans. Hexapods include the familiar six-legged creatures like spiders and centipedes, while arthropods includes everything from ants to bees. Myriapods are tiny creatures with many legs; they make up a large portion of the insect world. Crustaceans include crabs, shrimp, and lobsters.
Hexapods are distinguished by the six pairs of legs they possess. These legs are typically segmented, meaning that they are made up of several smaller pieces that can move independently. Hexapods have good mobility and can move quickly over the surface of the ground or across the water. They are also able to climb onto surfaces and move around inside small spaces.
Hexapods are typically predatory animals that rely on their sharp claws and teeth to capture their prey. They may eat small invertebrates or larger creatures, such as spiders or insects. Some hexapods, like scorpions, are venomous and can inject their victims with a powerful poison.
