32 Schooling in fishes has been hypothesized to serve to

True or False????????????????????????/

33 Both lampreys and hagfishes lack jaws and feed by suction with a muscular mouth and teeth.

34 All sharks must swim continuously to respire or else they drown.

35 Most cartilaginous fishes have smooth skin.

36 Sharks are one of the leading causes of human deaths in coastal towns.

37 With a few exceptions, such as manta and devil rays, most rays and skates are demersal.

38 Flatfishes have bodies compressed top-to-bottom as an adaptation for their demersal lifestyles.

39 Structural colors in fishes result from crystals that act like tiny mirrors.

40 The presence of colored stripes, bars, or spots on reef fishes generally is a form of warning coloration associated with toxins or bad taste.

B41 Sharks often have a large upper lobe on their tails primarily to act as a rudder for steering.

42 A much greater diversity of fin shapes and uses has evolved in the bony fishes than in the cartilaginous fishes.

43 Similar to humans, fishes have two-part hearts with one side pumping blood to the gills and back to the other side of the heart, which pumps blood to the rest of the body.

44 Both myoglobin and hemoglobin can store oxygen.

45 The lateral line of bony fishes is used to detect weak electrical fields of prey.

46 The coelecanth is a rare fish of biological interest primarily because it has fins with bones like those of land vertebrates rather than fin rays.

47 Territoriality behavior in fishes usually involves violent battles between defenders and invaders.

48 Schooling in fishes may be coordinated by vision, the lateral line, olfaction, and sound.

49 Tunas are major examples of anadromous fishes.

50 North Pacific salmon use primarily chemical cues when they migrate around the oceans as adults.

51 Dams, excess silt, and pollution are destroying Pacific salmon runs in rivers because they reduce the number of adults that return to the oceans after spawning.

52 The migratory behavior of the Atlantic Anguilla eels is essentially the opposite of that of the Pacific salmon.

53 Hermaphrodism in some fishes involves males changing into females or vice versa.

54 Special organs called claspers are used for internal fertilization in cartilaginous fishes.

55 Bony fishes reproduce primarily by internal fertilization.

56 Viviparity (live birth) such as found in mammals cannot occur in fishes because they always produce yolky eggs to support embryonic growth.
