Remarks
This is a more primitive group of spiders which includes the infamous tarantulas, primarily represented by members of Family Theraphosidae.
Some other familiar members include the trapdoor spiders and purseweb spiders.
Mygalomorphs are easily distinguished from Araneomorphs by two pairs or four booklungs.
Their fangs and chelicerae are parallel to the axis of the body.
