I remember when I was younger I played a game of hide and and seek with my brothers. I was hiding in my garage when all the sudden I saw a giant‚hairy wolf spider! I ran to my brothers and parents and told them what had seen‚ but when we got there it was gone. Many people have a horrible fear of spiders or arachnophobia.

INSECTS Insects‚ being larger and having a hard‚ chitinous and therefore impermeable exoskeleton‚ have a more specialised gas exchange system. Insects have no transport system so gases need to be transported directly to the respiring tissues. There are tiny holes called spiracles along the side of the insect. The spiracles are openings of small tubes running into the insect’s body‚ the larger ones being called tracheae and the smaller ones being called tracheoles. The ends of these tubes‚ which

Snails‚ clams‚ squids‚ chiton. Is it possible that they may all be related in some way? Could they come from the same family tree? How does an octopus related to an oyster other than living in water? Yes it is very true that all of the above named specimen evolved from the same ancestor. The hypothetical ancestral mollusk has evolved into so many different species that are adapted to live in a variety of environments.

Pesky Arthropods Oh‚ I absolutely despise those eight-legged arthropods capable of making you yelp‚ jump and hold onto something for dear life. The way the arachnid stares at you with those black beady eyes really gives you the heebie-jeebies. As it crawls towards you‚ you are absolutely petrified trying to figure out a way to execute it the most lethal way possible. Although‚ you may be a thousand times bigger than the specimen‚ it’s still able to give you a shiver down your spine. You might have

Rickettsias from infected vertebrates‚ usually mammals‚ live and multiply in the gastrointestinal tract of an arthropod carrier but do not
