Document Summary

A bilaterally symmetrical animal can be divided into mirror-image (left and right) halves by a single plane that passes through the midline of its body. Hox genes: bilaterian animals: are classified as either protostomes or deuterostomes, eumetazoans: all other animals, aside from sponges. The mouth is connected to a blind sac called the gastrovascular cavity: medusae of many species produce eggs and sperm and release them into the water. An individual medusa is male or female, releasing eggs or sperm into the open sea: anthozoans , sea anemones, sea pens and corals. It can be stretched to several times its resting length and then recoil, lungs and large arteries: cartilage and bone are connective tissues that provide rigid structural support. In hot fish a countercurrent heat exchanger is present, which is the blood vessels carrying blood in opposite directions. Instar : growth stage between 2 molts: majority of hormones are peptides or polypeptides (proteins).
