Invertebrate Terms
Insect development that includes egg, larva, pupa, and adult
Complete Metamorphosis
The process by which the female lays eggs and the male fertilizes them once they are outside of the female
External fertilization
This structure provides oxygen transfer
gills
Biologists have placed fishes into these three groups.
Jawless fishes, cartilaginous fishes, & bony fishes
For most amphibians, this is the major respiratory organ.
Skin
An eye made of many lenses, each with a very limited scope
Compound Eye
Body temperature relies on environmental temperature
Ectothermic
This organ helps the fish to stay afloat in the water.
Air bladder
The dorsal fins in both sharks and boy fish provide this function.
Stabilize the fish and keep it upright as it swims
Describe the difference between a toad & a frog.
Frogs have smooth, shiny skin that dries easily, so spend a lot of time in water. Toads have dry, bumpy skin & only return to water to reproduce.
A body covering, typically made of chitin that. provides support and protection.
The lobe of the brain that controls involuntary actions & refines muscle movement
Cerebellum
This organ stores bile
Gall bladder
This is the shark's most sensitive means of finding prey.
Electrical field sensor
Reptiles share this growth-related characteristic with the arthropods.
Reptiles & arthropods must molt as they grow
A body region composed of the head and thorax fused together
Cephalothorax
Development that occurs in an egg that is hatched outside the female's body
Oviparous development
This organ secretes some digestive enzymes into the intestine & at the same time into the stomach that aids the breakdown of food
Pyloric ceca
Describe the major difference between the tail of a ray and the tail of a skate.
"Rays tend to have slender, whiplike tails, while skates tend to have thicker, fleshy tails." (p. 600)
List the 6 common characteristics of amphibians.
1. endoskeleton made mostly of bone
2. Smooth skin w/many capillaries & pigments (no scales)
3. 2 pairs of limbs w/webbed feet (usually)
4. As many as 4 organs for respiration
5. 3-chambered heart
6. Oviparous with external fertilization
Insect development that includes egg, nymph, and adult
Incomplete Metamorphosis
Development that occurs inside the female, allowing the offspring to gain nutrients and vital substances from the mother through a placenta
Viviparous development
The fish heart has this many chambers
two
The salmon's life cycle is called this.
Anadromous
State the 5 characteristics that set reptiles apart from the other vertebrates.
1. covered with tough, dry scales
2. extothermic
3. breathe. with lungs throughout their lives
4. 3-chambered heart with a ventricle that is partially. divided
5. produce amniotic eggs covered with a leathery shell; most oviparous, some ovoviviparous
