APS Trivia

[Fuscus]

It is the only species of snake to swim under my arm and check out my groin

 

[Slateman]

Boys this snake can do something what no other snake can

 

[ReptileRascals]

It can do major fluid shifts between nonvascular and vascular compartments to significantly compensate hypovolemia...

They also have an unusual lung system.
The trachea of the windpipe provides an "extra" lung which is endowed with blood vessels that leads into the "true lung" which in turn connects to an air sac called the "saccular lung" which is poorly endowed with blood vessels as it is mainly for oxygen.Olive sea snakes obtain between 10 and 22 per cent of their total oxygen needs in this way. They also purge large amounts of carbon dioxide through the skin.

 

[Morelia_man]

scales are smooth and don't overlap???

 

[ReptileRascals]

Whats the answer, whats the answer... lol

 

[sobrien]

They born with legs and they fall off at 3 months of age :lol:

 

[Slateman]

Wow this time we had lot of informations about tropical Sea snake.
Answer i was looking for is: 1: Light receptor on its tail 2:Able to navigate long distances.

Reptile rascal is getting 1/2 point for......It has a light receptor in its tail .....

All the other informations was right and we learn bit about this interesting snake.

Next question will be about same snake again LOL.
What function have light receptor on Tropical Olive Snake?

 

[ReptileRascals]

Used as a cordal lure lol
It feeds from dark rock crevices so it needs light lol

Nah the function of the tail is not known...

 

[python_guy44]

the light recepters act as a lure to prey which is used by alot of reptiles such as GTP( i think)

 

[Brodie]

I searched it and found out that the function is unknown..........

 

[wattso]

it can detect light with receptor in tail, possible aids navigation or mating in dark crevice by moonlight(romantic)lol probly to find their way to surface to breath every hour or so.

 

[almaron]

It is clearly a solar collector array for charging it's batteries.

 

[Morelia_man]

its to attract food. for example the little fish (lunch) will see the light and go and see what it is then gobble gobble no more fish. cos its so dark where they live it really stands out.... just a guess

 

[Magpie]

Ummm receptors don't usually give much light out to use as a lure.
I could be wrong but they usually receive light, hence 'receptors'..

 

[Slateman]

Thank you for your answers people. Some of them can be right, but not proven. Nobody really know yet.
1 point is going to reptile rascal for answering first ...ah the function of the tail is not known...

Score so far:

Fangs 1 point
reptile rascal 4+1/2 points
Astrobeca 1/2 point
Fuscus 1 point
Morelia man 1/2 point
brendan_spencer 1/2 point

Another question:

To which living snake is Acrochordidae closely related ? And how many species is in this superfamily worldwide?

 

[ReptileRascals]

3 species in the family..
Closely related to blind snakes...

Javan Wart Snake

 

[Guest]

Family Acrochordidae (Wart Snakes)
Only 3 species belong to this family.

Appearance: Heavy-bodied snakes with skin lying loose in folds. Scales small, granular and non-overlapping, giving a rugose texture with the interstitial skin forming bristle-tipped tubercles. Adapted to aquatic lifestyle by dorsally-shifted eyes, valvular nostrils, and a flap for closing the lingual opening of the mouth. Acrochordus granulatus has a laterally compressed tail and lingual salt glands.

Size: 60-180 cm snout-vent length.

Distribution: Indo-Australian region

Habitat: Aquatic; estuarine-marine (Acrochordus granulatus) or living in freshwater (A. arafurae, A. javanicus).



Wart Snake (Acrochordus granulatus) ? Ashok Captain

Food: mainly fish.

Reproduction: Ovoviviparous with litters ranging from 2 to 32 neonates (A. javanicus). Clutch size is correlated with body size. Acrochordus granulatus: 4-8 neonates.

Behavior: Slowly moving and swimming animals which often remain under water for a considerable time. On land they can move only clumsily

Taxonomy: The systematic status of the Acrochordidae has been unclear for many years: some authors placed them within the colubrids (as a subfamily), others such as UNDERWOOD (1967) placed them within the Henophidia. More recent authors placed the acrochordids within the caenophidian radiation (GROOMBRIDGE 1984, RIEPPEL 1988).

[ReptileRascals]

Acrochordidae = the wart snake or file snake family.
So the Javan wart snake isn't closely related it is part of the same family...

um brendan spencer, this is supposed to be your knowledge not what you can find on the so you can copy and paste....
