Spiders' Fishing Techniques
Some spiders
hunt in even the most unexpected environments. For example,
the hunting field of the water-spider Dolomedes is the surface
of water. This spider is mostly to be found in shallow places
such as marshes and ditches.
The water-spider, which lacks good eyesight, spends most
of its time by the side of the water spinning threads and
spreading them over its surroundings. These serve two functions
at the same time: they are a kind of warning to other spiders,
setting the limits of its own territory, and they also form
an escape route in the event of unexpected danger.
The spider's most frequently used hunting method is to put
four of its legs on the water while the other four hold on
to dry land. While doing this, it employs a most clever technique
to avoid sinking. The spider covers those of its legs which
will go into the water with a water-proof coating by passing
them through its fangs. It then approaches the edge of the
water. Pushing its body down with great care, it moves on
to the surface of the water. It places its fangs and feelers
under the water in such a way as not to disturb the surface.
It waits for a living creature to approach, with its eyes
looking around it and its legs feeling for vibrations in the
water. To feed itself, the spider needs to find prey at least
the size of the "Golyan" fish.
When the spider is hunting, it stays motionless until the
fish comes within 0.6 inch of its jaws. Then it suddenly enters
the water, catches the fish in its legs, and bites it with
its venomous fangs. Then, in order to stop the fish, which
is much bigger than it, from dragging it under the water,
it immediately turns upside down. The venom quickly takes
effect. It not only kills the prey, but also dissolves the
prey's internal organs, turning them into a kind of soup and
making them easy to digest. When the prey is dead, the spider
drags it on to the shore and feeds. (Science and Technology

At this point various questions spring to mind. How did the
spider come by that wax which stops it sinking? How did it
learn to coat its legs with it against the risk of sinking?
How did the spider come by the wax's formula and how did it
make it? The spider certainly did not bring about all of these
things-each one of which bears the mark of intelligence-of
its own volition. Like all other living creatures, this species
of spider acts in such an intelligent way, is capable of making
such a plan and putting it into practice by inspiration from
God. In one of His verses, God states that He gives every
creature its own provision:
There is no creature on the Earth which
is not dependent upon God for its provision. He knows where
it lives and where it dies. They are all in a Clear Book.
(Qur'an, 11:6)
