Tree spider |
When
I was a child like my other friends, I was scared of spiders. Even now when I
see a spider in my room, certainly I do not scream, but yet, I avoid them and
try to chase them out from my room. When I grew up little by little, I wanted to
get rid of this fear and crazy imaginations about spiders, so I started reading
about spiders in order to get familiarize with these little fascinating creatures.
We
all know that spiders are disliked by many people due to their lack of knowledge
about spiders. According to the taxonomy of spiders, they belong to the class
Arachnida Phylum Arthropoda. These spiders are carnivores which mean they feed
on small insects or flesh. They do it by trapping their pray using their web or
by hunting on ground. In addition, these spiders can be seen all over the world
except in air since they do not have wings to fly and in ocean since they are
air-breathing animals. Yes, there are some spiders who can live under water
such as Diving Bell Spider ( Argyroneta Aquatica) but they also
need air. In this case they trap air in a bubble held by hairs on its abdomen
and legs.
Another
reason is their size and the appearance which give an expression that they
should not be petted or loved, they are venomous and dangerous. When we
consider about their size, most spiders are relatively small (2-10 mm) but
there are exceptions like Tarantula whose body length will extend up to 80-90
mm. Even though size varies from one spider species to another, their body
consists of two main parts. First part is the “Cephalothoraxe” (Prosoma) which
is the anterior part and the other part which is the posterior part, known as
“Abdomen” (Opisthosoma)
