Glossary

  • Abdomen: in arthropods (crustaceans, insects and arachnids) the abdomen is the hind region of the body, which is usually segmented to a degree (but not visibly in most spiders). In crustacea (e.g. crabs) some of the limbs attach to the abdomen; in insects the limbs are attached to the thorax (the part of the body nearest to the head) and not the abdomen. In vertebrates the abdomen is the part of the body that contains the internal organs (except the heart and lungs).
  • Antennae: pair of sensory structures on the head of invertebrates.
  • Carapace: the top shell of a turtle. In arthropods (insects, crabs etc), the fused head and thorax (the part of the body located near the head) also known as ‘cephalothorax’.
  • Exoskeleton: the horny shell-like skeleton that encloses the body of all Arthropoda.
  • Invertebrate: animals with no backbone.
  • Reintroduction: putting an animal or plant into an area where the species or sub-species previously lived but from which they are locally extinct - usually referring to projects aiming to re-establish self-perpetuating populations.
