CHORDATES
VERTEBRATE
FISH
AMPHIBIANS
REPTILES
100
They have four characteristics at some stage of their development: a notochord, postanal tail, nerve cord, and gill slits.
What is a chordate?
100
The internal framework of all vertebrates.
What is an endoskeleton?
100
Lampreys and hagfish are these type of fish
What are jawless fish.
100
This word comes from the Greek word "amphibios" which means double life.
What is Amphibian?
100
Ectotherms with a thick, dry, waterproof skin.
What are reptiles?
200
The muscular structure at the end of the developing chordate.
What is a postanal tail?
200
Vertebrae, of the backbone, are separated by these soft disc of flexible tissue.
What is cartilage?
200
Sharks, rays, skates, fluke, and flounder are these type of fish.
What cartilaginous fish?
200
In cold weather,when ectotherms become inactive and bury themselves in mud or leaves until the temperature warms.
What is hibernation?
200
These reptiles have a four- chamber heart, so oxygen filled blood does not mix with carbon dioxide filled blood. All other reptiles have a three- chambered heart.
What are crocodiles?
300
Above the notochord and along the developing chordate's body, is this tubelike structure. The front end usually developes into the brain, and the remainder becomes the spinal cord.
What is the nerve cord?
300
Vertebrate, whose internal body temperature changes with the temperature of its surroundings, also called cold- blooded.
What is an ectotherm?
300
Seahorses are an example of this type of bony fish.
What are Ray-finned Fish?
300
The period of inactivity when ectotherms burrow into the ground during hot, dry months.
What is estivation?
300
An example of an extinct reptile.
What is a dinosaur ?
400
They are found in the region between the mouth and the digestive tube, in developing chordates
What are the gill slits ?
400
Encloses and protects the brain, in all vertebrates.
What is the skull?
400
These fish are thought to be the link to the first land animals, the amphibians. Their fleshy fins have jointed bones.
What is the lobe-finned fish?
400
The tiny blood vessels , directly beneath the amphibian's moist skin and in the lining of the mouth, that makes it possible to exchange carbon dioxide with oxygen. Some salamander have no lungs and breathe only through their skin.
What are capillaries?
400
The largest group of reptiles, their jaw has a special joint that unhitches to increase the size of their mouth.
What are snakes and lizards?
500
Internal support, along the upper part of the developing chordate. In fish, amphibians, reptiles, birds and mammals, backbones partly or entirely replace this. In sea squirts, tunicates and lancelets, it is kept into adulthood.
What is the notochord?
500
The vertebrate , whose vertebrae and ribs are fused to the inside of the top of the external plates, which forms a shell
What is the turtle?
500
This fish will drown, if kept submerged in water.
What is the Lungfish?
500
Fish have a two-chambered heart. This is the number of heart chambers for amphibians
What is three?
500
These reptiles have no teeth.
What are turtles?
