A supporting rod called a notochord. The notochord is located just below the nerve cord, toward the back (i.e dorsal). Vertebrates have an embryonic notochord that is replaced by the vertebral column during development. 2.A dorsal tubular nerve cord. Tubular means that the chord contains a canal filled with fluid.Arthropods are coelomate organisms characterized by a sturdy chitinous exoskeleton and jointed appendages.

Scorpions are principally predators of arthropods. Human stings are accidental and constitute a protective reflex by the scorpion. The prey is detected by a large number of diverse sensory organs. Scorpions make little use of vision for prey detection: rather, they mostly use mechanoreceptors and chemoreceptors.Arachnids include spiders, scorpions, ticks, and mites. These arthropods have eight legs and are almost entirely terrestrial. They are a diverse group as well, containing over 100,000 species. Most arachnids have two body segments - a cephalothorax and an abdomen.In many species, the tail is absent or reduced; for example, in apes, including humans, it is present in the embryo, but reduced in size and nonfunctional in adults. Visual Connection Figure 15.33 In chordates, four common features appear at some point in development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.Arthropods are a type of invertebrate that includes animals such as crabs, spiders, and insects.

A unique feature of arthropods is the presence of a segmented body with fusion of certain sets of segments to give rise to functional segments. Fused segments may form a head, thorax, and abdomen, or a cephalothorax and abdomen, or a head and trunk. The coelom takes the form of a hemocoel (or blood cavity).Earwigs Prevention. One of the best methods of earwig control is to prevent any structural entry. Cracks and crevices should be well sealed with a silicone-based caulk, steel wool or a combination of both. This practice includes sealing doors and windows, as well as attic and foundation vents.
