Invertebrates

Lepidoptera. A branch of Insects. A Butterfly expert or scholar is called a Lepidopterist.=they are also insects. By the way spiders are not insects but are of the arachnid group. Mr. Bug Man!

Earthworms belong to the phylum Annelida (ringworms). Note that these are not the only kind of worms; two other phyla are Platyhelminthes (flatworms) and Nematoda (roundworms), and they're all very different from each other. For comparison, another phylum-phylum difference is that between either of the worms and Chordata, being all vertebrates!

Equatorial regions may consist of rainforests, dry deciduous forests, spiny forests, desert areas to name a few. You would need to be more specific in what equatorial regions you might be talking about.

They are:

Sponges (Porifera)

Comb jellies (Ctenophora)

Hydras, jellyfishes, sea anemones, and corals (Cnidaria)

Starfishes, sea urchins, sea cucumbers (Echinodermata)

Flatworms (Platyhelminthes)

Round or threadworms (Nematoda)

Earthworms and leeches (Annelida)

All species of lemurs are mammals and, like all mammals, they are vertebrates because they have a spine and spinal cord, and an internal skeleton. They belong to the Phylum Chordata.

Mammals, birds, fish, reptiles and amphibians are all vertebrates.

Oysters belong the the invertebrate group of mollusk.

Mainly through suspension feeding. Cnidarians use stinging tentacles (nomocytes) to capture their prey. Once the tentacles grab the food it is absorbed in the gastrovascular cavity (stomach) and taken in asnutrients.

Invertebrates have small nervous systems, consisting of many small brains. Since the neurons are distributed differently in their nervous systems, invertebrates are thought to have limited cognitive ability, and don't respond the same ways vertebrae do to stimuli.

Sea urchins have several adaptations to help them survive. To protect themselves from predators, sea urchins will react immediately if something sharp touches their shell and they will point all of their spines towards the area being poked. They are also light-sensitive. This is why they are nocturnal. This light sensitivity also allows sea urchins to move their spines in reaction to shadows. In order to protect themselves from being swept away from the powerful ocean currents and waves, sea urchins lodge themselves into holes or crevasses. Finally sea urchins, somewhat like starfish, have a certain regenerative ability. If a spine is damaged or lost, a sea urchin can rebuild it. However if there is too much extensive damage to the test, the sea urchin won't be able to heal it.

Arthropoda. Five groups are- Trilobitomorpha, Chelisrata, Myriapoda, Hexapoda, Crustacea.

No, that is why they are called invertebrates. Animals with back bones are called vertebrates (Latin vertebrus, having joints, from vertebra, vertebra) and invertebrates are the opposite.

The compostable, living material is broken down in compost bins and piles by the meeting of proper levels of air, moisture, and temperature; and to the regular turning over of the pile. Added to the proper environment is the role of microorganisms, and of macroorganismssuch as ground beetles. And there may be the introduction of composting worms. Any and all of these factors contribute to the decomposition of compostable materials into dark brown, fresh-smelling, organic matter-rich soil.

Toads have a spinal cord and backbone, which means they are vertebrates.

All arthropods, which are invertebrates, have bilateral symmetry. Arthropods include all insects, centipedes, millipedes, crustaceans and arachnids.

Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

Whelks are large marine snails (Buccinidae family) with pointed spiral shells. Some varieties of Whelks are commonly eaten as a delicacy in Europe. They have no internal skeleton or backbone so they would be classed as invertebrates.

No. Cheetahs, like all mammals, are vertebrates, because they have spines.

Yes,the father of any animal is always bigger than the mother.

Is a bunny is a invertebrate or a vertebrate

Phylum arthropoda are also called jointed legged animals. They have exoskeleton and segmentations. Some good examples are crustaceans, insects and arachnids. Examples of crustaceans are crabs, crayfish, and lobster.

Dragonfish, like all fish, are vertebrates because they have a spine and spinal cord, and an internal skeleton. They belong to the Phylum Chordata.

Mammals, birds, fish, reptiles and amphibians are all vertebrates.

No, like all insects it is an invertebrate. It does not have a bony skeleton, so no vertebrae. Its hard outer casing, called an exoskeleton, gives the body its shape.

Flies are generally considered to be pests, but they do serve a purpose. This purpose is served in the ecosystem. When flies lay their eggs, maggots help to break down garbage and organic matter. Flies also help to pollinate crops as fly around them.
