• spiny
  • The second antennae may be significantly reduced (e.g. remipedes), apparently absent (e.g. barnacles), or modified to such an extent that they no longer resemble antennae (e.g. spiny lobsters and slipper lobsters). (wikipedia.org)
  • clades
  • The group is generally regarded as monophyletic, and many analyses support the placement of arthropods with cycloneuralians (or their constituent clades) in a superphylum Ecdysozoa. (wikipedia.org)
  • cockroaches
  • Herpomyces periplanetae is a very widespread parasite on the antennae of adult cockroaches in the genus Periplaneta, like the common American cockroach, Periplaneta americana. (wikipedia.org)
  • prey
  • Workers are strictly nocturnal (active mainly at night) and are solitary foragers, collecting arthropod prey and sweet substances such as honeydew from scale insects and other Hemiptera. (wikipedia.org)
  • larvae
  • Longicorn beetles are sometimes called long-horned beetles, nicknamed for their very long antennae, or timber beetles, because the larvae tunnel into wood). (amnh.org)
  • legs
  • The mandibles, clypeus (one of the sclerites that make up the "face" of an arthropod or insect), antennae and legs are pale yellow. (wikipedia.org)
  • The hairs on the body are yellow, erect and long and abundant, but on the antennae and legs they are shorter and suberect (standing almost in an erect position). (wikipedia.org)
  • Periplaneta
  • We determined the open-loop dynamics of a tactile sensor, specifically the antenna of the American cockroach, Periplaneta americana , an animal that escapes predators by using its antennae during rapid closed-loop tactilely mediated course control. (biologists.org)
  • groups
  • Her research is extremely complex, requiring knowledge of arthropods and plants and the interaction between the two groups of organisms. (amnh.org)
  • Likewise, the relationships between various arthropod groups are still actively debated. (wikipedia.org)
  • membrane
  • However, the antenna does not hang free on the membrane, but pivots on a rigidly sprung projection from the rim of the torulus. (wikipedia.org)
  • group
  • Antennae can also locate other group members if the insect lives in a group, like the ant. (wikipedia.org)
  • The group has the open circulatory system typical of arthropods, in which a tube-like heart pumps blood through the hemocoel, which is the major body cavity. (wikipedia.org)
  • Animals
  • The arthropods, or "joint-footed" animals, also fill every imaginable environment, from the deepest ocean trenches to the highest mountain peaks, from the frozen wasteland of Antarctica to the broiling Mojave Desert in the western United States. (scholastic.com)
  • Thanks to their exoskeletons, arthropods became the world's first land animals some 300 million years ago. (scholastic.com)
  • Like all animals, arthropods need oxygen to survive. (scholastic.com)
