animals without a backbone. At least 97% of all animal species are invertebrates; with the exception of insects, most invertebrates are marine species.

the phylum comprising all animals that lack a backbone or spinal column

animal without internal skeletons, such as insects, crabs and shrimp

the most primitive of the chordates; lack a backbone.

Collective term for all animals which are not vertebrates; includes protozoans, sponges, jelly fish, worms, snails, insects, crabs, sea stars, etc.

species such as spiders, beetles and other insects who have no backbone.

Scientifically speaking, they are any animal which lacks a backbone. It is most commonly used to describe coral, but scientifically describes snails and other shelled fish.

Large group of lower animals that lack a spinal column.

Animals that have no backbones. Compare vertebrates.

All animals that don't have a backbone or internal skeleton. Examples: worms, insects, jellyfish, snails

Any animal that does not have a backbone.

Animals without internal skeletons. Some require magnification to be seen well, while others such as worms, insects, and crayfish are relatively large. Invertebrates living in stream and lake sediments are collected as samples to be identified and counted. In general, more varied invertebrate communities indicate healthier water bodies.

Animals without internal skeletal structure.

Animals lacking a dorsal column of vertebrae or a notochord.

lacking a spinal column; also : of or relating to invertebrate animals

These are animals without backbones. Examples of invertebrates include snails, crayfish, shrimp corals and crabs.

kirihe whaituara Animals with no bones.

This is a collective term for all those animals which do not belong to the phylum Chordata (i.e. those without a backbone, or vertebral column). This is a general term and is not a scientific classification.

animals without a backbone like octopus, sea anemone, and starfish

Animals that do not have backbones. Instead, their bodies are supported by an exoskeleton (as in arthropods) or body fluids (as in sea anemones). Invertebrates include insects, worms, snails, crabs, sponges and sea stars. More than 90% of all animals are invertebrates.

those multi-celled animals that lack an internal skeleton.

Animals without backbones or internal bony skeletons. All animals except for the phylum Chordata (vertebrates) fall into this category, including insects, crustaceans, worms, corals, and mollusks.

These are animals without backbones. In freshwater aquaria only snails and crayfish/shrimp are generally available. For marine aquaria, many kinds of animals are available.

animals without backbones, such as clams, squids, ammonoids, snails, crabs, insects, etc.

Animals without a backbone, for example shellfish, worms, jellyfish, sponges, seastars and corals.

Lacking a backbone or spinal column.

Small organisms, such as clams and worms, that lack a spinal column. Many of these filter bottom sediments and water for food.

Usually defined as animals without backbones, invertebrates make up the vast majority of all animal species. Only fish, amphibians, reptiles, birds and mammals are not invertebrates. Insects, spiders, worms, slaters and many marine creatures such as corals, sponges and jellyfish are examples of invertebrates.

Any animal which lacks a backbone. It is most commonly used to describe coral, but scientifically describes worms, snails, clams, and other shellfish.

animals that do not have a backbone.

animals without a backbone; the majority of animals living on earth are invertebrates; their diversity is far greater than those of vertebrates; 30% of all living animals are beetles

Animals without a spinal column (backbone).

Animals with no backbones. This group includes mollusks, crustaceans, worms, corals, and composes a large number of reef inhabitants.

Animals without backbones, including worms, insects, shrimps, crabs, snails, shellfish and zooplankton. Macroinvertebrates are large enough to be seen without the aid of magnification; microinvertebrates need to be viewed through a microscope.

Animals without internal skeletons. Some require magnification to be seen, while others such as worms, insects, and crayfish are relatively large. Benthic invertebrates are an important link in the food chain for fish and can be used as an excellent indicator of stream and river water quality. In general, higher numbers of species present in invertebrate communities indicate water bodies with good environmental conditions.

animals without backbones including zooplankton, shellfish, worms, insects, shrimp, crabs and snails.

Animals without backbones. This can include corals, snails, and shrimp or crabs.
