Poison Dart Frogs

She is supposed to be a poison dart frog.

if they migrate they would have to swim in water

They sleep in their habitat. Like if they live in the zoo, they sleep in the zoo. If they life in the forest, they sleep on the floor.

To date, the only known natural predator of poison arrow frogs is a snake known as Liophis (Leimadophis epinephelus). This snake has developed resistance to the frogs' poison.

I'm sorry, but I cannot assist with that.

Water obviously.

A poison arrow (or other frog) does not have ears per sebut has what is called a tympanum on their head behind each eye. It picks up vibrations and transfers them into the inner part of the frog's head where the rest of the organs of hearing are located. Recall that the frog's "ears" have to work under water, and the "ear" of a frog (or toad) is completely covered by the tympanum. The frog's other hearing organs are behind the tympanum in the inner head. Got links if you want 'em.

A blow dart can be used for shooting darts, usually dipped in poisons. It was commonely used as a weapon during specific times in history; times which, I apologise, can not remember.

1) Body covered with feathers . Functions: PROTECTION of body, COLOURATION (either camouflage or flamboyant), INSULATION (very important in small birds) and sometimes for FLIGHT.

2) Females lay fairly large EGGS with a CHALKY external SHELL. FERTILISATION is INTERNAL, and shell is added later. Eggs are normally laid in a nest, and the eggs are looked after by male or female, or both birds. Eggs are incubated, i.e. kept at correct temperature and tended, e.g. turned at intervals. n.b. Flight would be difficult if females retained the heavy eggs inside the body.

3) ADAPTATIONS for FLIGHT:

- front limbs form wings

- breast bone has " keel " to which wing muscles are attached.

- bones are very light, having AIR SPACES

- lungs have extra air sacs (near main muscles) to increase capacity (maybe also cooling).

- STREAMLINED body shape - no external ears - some have bony plates in eyes to resist wind pressure

- FEATHERS are light yet form large surface area

4) Birds have no teeth, but a tough beak for pecking food, and a gizzard containing stones to grind up food. Beaks show modifications according to function.

5) WARM BLOODED.

6) Legs covered with scales ( a link with reptiles?). Usually each foot has 4 toes with claws, but flightless birds may have 3. Much adaptation according to lifestyle.

7) CLOACA - common opening of urinogenital and digestive tract, no external sexual organs.

8) COURTSHIP displays may be complex, Male is usually brightly coloured ( a risk which has evolutionary advantages?).

9) PARENTAL CARE of young is a notable feature, but much of BEHAVIOUR is instinctive .

By way of exceptions that prove the rule, list some examples of species of birds that are (naturally) unable to fly.

Use an encyclopedia or other reference book to find some examples of birds that have beaks and feet that are specially modified to suit their lifestyle. You should be easily able to find 4 examples of each. For each, give the name of the species of bird, and either write a sentence describing the beak, or feet, and how it is adapted, or draw a simple line diagram of these parts of the body. Fantastic art is not expected!

CHARACTERISTICS OF MAMMALS

1. Body covered with hairto greater or lesser extent.

Functions: physical protection of body, insulation to reduce heat loss, provide coloration - usually camouflage.

2. Young are nourished by milk secreted by special MAMMARY GLANDS of female.

3. Skin has SWEAT GLANDS to cool body if required.

4. Sheet of muscle called DIAPHRAGM separates cavity of thorax (chest) from abdomen.

5. TEETH SPECIALISED for various functions , e.g. gripping, tearing, chewing.

6. EARS often have EXTERNAL FLAPS (pinnae) to direct sound waves to inner ear.

7. Brain and NERVOUS SYSTEM well developed, especially forebrain.

8. "Warm blooded" - CONSTANT BODY TEMPERATURE. General body functions more efficient than lower classes, e.g. better maintenance of body conditions.

A variety of HOMEOSTATIC MECHANISMS keep internal body conditions stable, e.g. concentration and pH of blood, which supplies all organs of the body (see later)

9. PARENTAL CARE is highly developed, and young depend on parents for a considerable time.

There are 3 main groups of mammals, which show a pattern of evolutionary development and increasing adaptability which may account for their success in COLONISING much of the Earth.

MONOTREMES

- the most primitive mammals - only 3 species:

duck-billed platypus, and 2 types of echidna (spiny anteater).

a) LAY EGGS (with LEATHERY, not chalky SHELLS). Platypus builds nest, and echidna develops pouch.

b) No specific mammary glands - NO TEAT - milk exuded from skin surface.

c) Adults have NO TRUE TEETH, but specialised feeding structures.

d) DISTRIBUTION: Australia, Tasmania, New Guinea.

MARSUPIALS

- Kangaroos, wallabies, koalas, wombats, opossums, etc.

a) Give birth to very SMALL and POORLY DEVELOPED live young.

b) Young are protected inside a POUCH in the female's lap, containing a teat providing MILK for nourishment.

c) Have only one set of teeth.

d) DISTRIBUTION: Australasia, S. America, and 1 species in the U.S.A.

DISPLACED by the more efficient (?) true mammals, but have diversified along similar lines.

PLACENTAL (TRUE) MAMMALS

- most well-known and widespread mammals, common and exotic

a) Young are born fairly WELL DEVELOPED after quite a LONG PERIOD inside the female's body (gestation period). The developing young are nourished by the PLACENTA which enables them to use the FEMALE'S BLOOD system:

- to provide food and oxygen

- to remove waste products

- to keep constant internal conditions.

b) Young continue to be suckled after birth by mammary glands.

c) Have 2 sets of teeth (see later).

d) Placental mammals have been SUCCESSFUL in EXPLOITING many ENVIRONMENTS on Earth, and have DIVERSIFIED into many types, widely DISTRIBUTED. MAN is a placental mammal.

They wait for insects to eat to come by, and maybe for a chance to breed with another frog. And they try to keep away from any animal that might want to have a go at eating them.

Blue Dart Express packages can be tracked in various ways depending on how they were shipped. With InternetDart the shipment can be tracked on for the last 45 days. Other tracking services include ShopTrack, PackTrack, MobileDart, ShipDart, and ImageDart.

because of their skin they got the name "poison dart frog"

male poison dart frogs call to other males to defend their territory. males fight to determine dominance. that is some of there behaviour, hope this helps:)

There are a huge number of species of poison dart frogs. They are all different colours, but most of them are extremely brightly coloured. Bright colours on animals in nature are often called 'warning colours'. Their bright shades of red, green, yellow, purple and blue, often iridescent and spotted or striped, clearly say 'don't eat me, I'm poisonous'.

since the blue poison dart frog lives in a warm constant climate, it never really has to hibernate or migrate anywhere. It is active year round.

It's pretty much invulnerable. Except from humans. A poisonous tree frog as poison in its skin and sweat, making it fatal to animals who attempt to eat it. It's called the poisonous tree frog for a reason

The blue dart frog (scientific name: Dendrobates azureus) makes a buzzing sound.

amphibian

up to 3 babies

almost all poison dart frogs weigh about 17-24mm in length

the golden frog's native habitat is in the rain forest of Panama, but it is rarly seen anymore within their native home.

Sorry, most sources I've read place the golden poison dart frog in Columbia.

i.e. Wikipedia, national geographic, etc

Phyllobates terribilis, the Golden Poison Frog or the Golden Dart Frog, is a poison dart frog endemic to the Pacific coast of Colombia.

All frogs are endothermic, or "warm-blooded" contrary to popular belief.

Lehmann's poison frog was created in 1976.

the most endangered frog is the blue poison dart frog!!!
