Crocodiles

The young will eat stones to help with ballast, also as an aid to grind food up in the stomach

What kind of location will a puffadder choose for its ambush site?

They emerge at dusk and will lie in cover to ambush their prey. Puff adders move in 'caterpillar' style and often climb into low shrub to bask or while away the time until their prey passes by. They are also known to hide in thick grass or under bushes, down holes, and under any form of ground cover. They usually wait in ambush in a spot where they can remain motionless for hours.

A puffadder usually sets up its ambush by frequently-used animal (or people) paths, mainly as the puffadder uses its highly-developed sense of smell via its tongue to locate animal scents left along these trails.

OWN and Elzet :thumbs_up: :thumbs_up: You both have elements of the question correct :clap:

The puffadder will definitely choose a location alongside of a trail that is used by animals, particularly rodent trails which appear frequently in the bush. (as a side, when doing a study on snake activity time budgets one of the characteristics recorded is whether the snake is alongside a trail and this is used to determine whether it is in ambush or not).

The next important features about the location a snake will choose is that it selects for a shady spot, which is significantly lower in temperature than the surrounds, such as beneath the canopy of a tree or under the base of a thick tuft of grass.

(interesting fact is that most rodents occupy a 10 square metre territory for their entire lives :shock: so often the ambush sites will be located near these).

OWN you are IT! :clap: :thumbs_up:

Give me a slightly drawn-out moment to respond ...

There are several varying scientific descriptions of what a reptile actually is.
Why is there this discrepancy - in other words, why is it so difficult to define what a reptile is?

Another good one Own :thumbs_up:

Has it got something to do with which species present day reptiles are descended from? Some reptiles descend from mammal like animals whilst others descended from true reptiles (although all mammals, birds and reptiles developed from the original reptile). In other words, reptiles should really be split into several groups depending upon which ancestor they evolved from.

Nice Q OWN :clap:

:hmz: I think Barcud may be on to something as I know based on phylogenetics that tortoises and turtles are actually more related to mammals than they are to other reptiles, specificlly snakes and lizards, while crocodiles are evolutionarily more similar to birds.

Will put some more though into it :hmz:

Barcud and Oddesy - you're both heading in the right direction, and are definitely onto something. Think a little more and then tell me why reptiles are difficult to accurately define.

Because some lay eggs and others give birth to live young?

That is but one of the factors; you've essentially all hit the nail, but now you need to identify which nail. :wink:
