Here's what I got out of a book titled "Spiders and Scorpions" by Rod Preston-Mafham...(how many females get books such as this from friends for Christmas, rather than clothes or jewelry? Oh well, I am who I am.)

1,2,3,&4 all TRUE.
Bigman, which of the three made you say False on #3?

As far as #4- the book says "The male uses his jaws to transfer sperm, which he has first released onto the ground, into the female's reproductive opening. Alternately, the sperm may be transferred directly into the female, the jaws being used to complete the insertion process."

What do you have further on this question, Timepilot?

And #5 is False I combined the fishing spider (which does catch tadpoles as part of its diet) with the net-throwing spiders, who do throw nets over their prey....but not tadpoles. I'll try to post the illustrations from the book, if it works. (The way the fishing spiders collect air bubbles to fill their nest and allow them to live in the water fascinated me, as well as the ability of the net casters to construct and use such a tool as a net!)

So, I'm at a standstill on who's unlucky enough to be IT.

Whoever is clever fastest....go for it.

Pseudoscorpions.
Please note that I am no expert. I base my answers purely on my interpretaion of Internet research.

Although Wikipedia suggests that the answer is T,

During digestion, pseudoscorpions pour a mildly corrosive fluid over the prey, then ingest the liquefied remains. - http://en.wikipedia.org/wiki/Pseudoscorpions

I have known this source to be wrong on a number of occasions.

Other sources state:

1. They use the pedipalpi and chelicerae to subdue their prey; some species also use venom secreted by the chelae. - http://www.arc.agric.za/home.asp?PID=1&ToolID=63&ItemID=1769

2. Most pseudoscorpions have poison glands in their pincerlike claws which they use to paralyze prey. They inject a saliva into the victim; the pseudoscorpion feeds on the liquified contents. - http://www.extension.umn.edu/yardandgarden/ygbriefs/e610pseudoscorpion.html

3. Prey items are caught by means of the large, chelate pedipalps, and are passed to the chelicerae where digestive juices are injected. - http://www.encyclopedia.com/doc/1O8-Pseudoscorpiones.html

Interesting questions 8)

True or False:

A) The central purpose of national parks is to conserve ecosystems
rather than species.

B) The genetic makeup of all Cheetahs is virtually identical.

C) The thorns of acacia trees become embedded in the coating of the
giraffes tongue as it feeds on them, slowing the feeding to a level tolerable
to the plant.

D) Vultures get most of their food hanging around predator kills.

E) The Bateleur which is restricted to the Lowveld in South Africa is
usually the first bird to arrive at a predator kill.

I'm SO confused! Story of my life....

Here's naturelovers response: TFFFF
So if 4 0f 5 are incorrect, it has to be one of these:
TTTTT
FFTTT
FTFTT
FTTFT
FTTTF
But if B3006 has only one wrong with TTFFT...it has to be:
FTFFT
TFFFT
TTTFT
TTFTT
TTFFF
I don't see a reconciliation between the two....

A) The central purpose of national parks is to conserve ecosystems
rather than species.


True: The essential difference between a national park and other
institutions devoted to conserving biological diversity is that national
parks preserve not only the plants and animals, but also the processes
that allow them to survive and adapt to a changing environment. In
other words the central purpose of national parks is to conserve
ecosystems rather than species.

B) The genetic makeup of all Cheetahs is virtually identical.

True: The genetic makeup of all cheetahs is virtually identical. The world
population must have been reduced to a handful of individuals at some
time thousands of years ago. This would have led to a reduced gene pool
and eventually to a similarity of genes once the population recovered.

C)The thorns of acacia trees become embedded in the coating of the
giraffes tongue as it feeds on them, slowing the feeding to a level tolerable to the plant.


True: Giraffe are not deterred by thorns but their rate of feeding is
reduced to a level tolerable to the plant. The thorns embedded in the
thick mucous covering of the tongue are gradually shed as it is replaced
with new cells.

D) Vultures get most of their food hanging around predator kills.

False: Contrary to popular perception that vultures get most of their
food by hanging around predator kills, this source accounts for less than
one tenth of their food intake. They get most of their food from animals
dying of natural death, road kill etc.


E) The Bateleur which is restricted to the Lowveld in South Africa is
usually the first bird to arrive at a predator kill.


True: The Bateleur was once widespread in South Africa but is now
restricted to the Lowveld. It is common in the skies around Pretoriuskop
and a few other areas is Kruger and you may be lucky enough to see it
performing aerial acrobatics. Although it is a bird of prey it obtains a large
part of its diet from carion, especially while young.
The Bateleur is highly maneuverable and adept at low-altitude cruising
which often makes it the first bird to arrive at a carcass.

Welcome to the quizzes Highland. :D
Well done!! :clap: :clap: All your answers are correct :thumbs_up: so you are next to post the questions.
