Mammal Exam Review - CHS Zoology

predator

Also known as secondary consumers - most carnviores

prey

Alson known as primary consumers - most herbivores.

reproductive behaviors

Mammals are put into 3 groups based on what behaviors?

Baleen

These are thin plates of fingernail-like material that hang from the roof of the cetacean mouth?

rodents

These types of mammals are also called the "gnawing mammals"?

synapsids

These were ancestors of mammals, that had one opening behind the eye, were small and looked like modern lizards.

echolocation

This is an ultrsonic method of sensory perception by which certain animals orient themselves to their surroundings, detect obstacles, communicate with others, and find food.

cecum

This is the large sac in the pseudo-ruminant that branches from the small intestine and acts as a fermentation chamber.

carrying capacity

This is the largest population that the resources of an environment, habitat, or ecosystem can support without being damaged.

cud

This is the portion of food that returns from a ruminant's stomach in the mouth to be chewed a second time?

ungulate

This term means "hoofed animal", and these animals walk on enlarged toenails called hooves.

pinniped

This term represents the seals, sea lions and walruses group because of their paddle-like forelimbs and hindlimbs.

cetacean

This term represents the whale and dolphin group that have fishlike bodies.

predator animals that are carnivores and only eat meat - example lions and wolves

What are secondary consumers?

hair, sweat glands, diaphragm, mammary glands

What are the characteristics ONLY found in mammals and NOT shared with another other animal group we have learned so far?

mammary glands

What are the modified, enlarged sweat glands that produce & secrete milk through nipples in which the young can suckle to obtain nutrition?

prey animals that are herbivores and only eat plants - example cows and deer

What are the primary consumers?

hair follicles

What are the skin cells called where hair grows from?

control their temperature internally

What does endothermic mean?

Their diet (what they eat)

What does the type, size and shape of teeth reflect in mammals?

hibernation

What is a state of inactivity and metabolic depression in animals, characterized by lower body temperature, slower breathing, and/or lower metabolic rate?

red blood cells lack nuclei

What is different about mammal blood?

elephant

What is the largest LAND mammal?

Blue Whale

What is the largest mammal in the world?

rumen

What is the largest of the four compartments in a ruminant digestive system where the bacteria and microorganisms are found?

diaphragm

What is the sheet of muscle called below the rib cage of mammals that aides in breathing?

mammalogy

What is the study of mammals called?

gestation

What is the term called which means carrying of an embryo or fetus inside a female VIVIPAROUS animal?

bats and cetacea (whales & dolphins)

What two types of mammal groups are known to use echolocation?

pseudo-ruminant

What type of digestive system has a simple stomach and an enlarged cecum that has the ability to digest fiber withe the help of microorganisms?

ruminant

What type of digestive system involves a four compartment stomach containing microorganisms modified to handle large amounts of fiber?

monogastric

What type of digestive system involves only a simple stomach typically found in omnivores or carnivores?

monogastric digestive system

What type of digestive system is the only one that DOES NOT use bacteria to help digest cellulose/fiber?

monotreme

What type of mammals lay eggs therefore are oviparous?

prey animals like elephants, deer, and cows

What type of placental mammal has the longest gestational periods?

predator animals like lions and wolves

What type of placental mammal has the shortest gestational periods?

Endothermic

What type of thermoregulation do mammals have?

odd-toed ungulates like horses

What type of ungulates typically have a pseudo-ruminant digestive system?

even-toed ungulates like cows

What type of ungulates typically have a ruminant digestive system?

placental

What type of viviparous mammals give birth to fully developed live young?

marsupial

What type of viviparous mammals give birth to underdeveloped young called joeys that complete their developement and growth in pouches?

herbivores

What types of animals ONLY eat plants?

omnivores

What types of animals can eat both plants (grains) and meat?

carnivores

What types of animals can only each meat?

intelligence

What typically determines mammal brain sizes?

neocortex

What unique part of the mammalian brain deals with higher brain functions?

predators

Who balances the carrying capacity of a habitat naturally?
