A hairy and very large arachnids belonging to the Theraphosidae family of spiders, of which approximately 900 species have been identified. The tarantula has a straw like mouth opening that only sucks. This means that anything it wants to eat has to be in a liquid form, pray like a mouse must be juice-i-fied.
Tarantula senses its environment using setae (hairs), even thought it has eyes touch is the best sense it has. It depends on vibrations to hunt, using its setae it can sense chemicals, vibration, wind, sound, and can even smell you.
Tarantulas have two set of breathing organs (lungs) that are like a book. The lungs consisting of 15 or more sheets, which are supplied by blood vessels. A tarantula’s blood is not true blood and it’s not the same as human; it has an oxygen-transporting protein. Tarantula’s heart pumps blood through tunnels (sinuses) all
over its body and not through veins.
