Front 1

Vertebrate Animal with a constant internal temperature

Back 1

Endotherm

Front 2

Supportive framework of bone and/or cartilage that provides an internal place for muscle attachment and protects a vertebrate's internal organs

Back 2

Endoskeleton

Front 3

Thin, liquid-filled, protective membrane that forms around the embryo.

Back 3

Amniotic

Front 4

Tough, flexible tissue that joins vertebrae and makes up all or part of the vertebrate endoskeleton.

Back 4

Cartilage

Front 5

Animal that has a notochord, a nerve cord, gill slits, and a postanal tail present at some stage in its development

Back 5

Chordate

Front 6

Backbones that are joined by flexible cartilage and protect a vertebrate's spinal nerve cord

Back 6

Vertebrae

Front 7

Cyclic response of inactivity and slowed metabolism that occurs during period of cold temperatures and limited food supplies

Back 7

Hibernation

Front 8

Vertebrate animal whose internal temperature changes when the temperature of its environment changes

Back 8

Ectotherm

Front 9

Fanlike structure used by fish for steering, balancing and movements

Back 9

Fin

Front 10

Muscular structure at the end of a developing chordate

Back 10

Postanal

Front 11

In developing chordates, the paired openings found in the area between the mouth and digestive tube

Back 11

Gill Slits

Front 12

Inactivity in hot, dry mouths during which amphibians hide in cooler ground

Back 12

Estivation

Front 13

Thin, hard plates that cover a fish's skin and protect its body

Back 13

Scales

Front 14

Tubelike structure above the notochord that in most chordates develops into a brain and spinal cord

Back 14

Nerve Cord

Front 15

Firm but flexible structure that extends along the upper part of a chordate's body

Back 15

Notochord
