Reptiles have evolved over time into four main groups based on skull structure: anapsids, euryapsids, synapsids, and diapsids. While reptiles' intelligence and emotions are debated, they are driven by natural instincts. Some people fear reptiles due to trauma, lack of knowledge, or an aversion to being near or touching them. Reptiles have adaptations like unhingable jaws and venom use that help them hunt and defend themselves. Snake venom serves defensive, offensive, and digestive purposes and comes in different types that impact nerves, blood, or tissue. The black mamba is one of the most deadly snakes due its speed, length, and neurotoxic venom.

•There were four
that this primitive
Four different groups of reptiles condition, and they are grouped
Anapsid (turtles/tortoises) according to the number and
location of extra holes (called
Euryapsid(plesiosaurs/icthyosaurs)Ex. apsids) in the back part of the
Synapsid(mammals like reptiles) skull.
Diapisd((all other reptiles/birds)

4. Herpetophobia(the fear of
reptiles)
 The main reason people fear reptiles are

 The lack of knowledge about reptiles
People that have Herpetophobia
react when they are:
 Touching

known

•Certain types of snakes
use venom to kill
•certain types of snakes
constrict to kill

6. Types of Snake venom and
purpose of it.
 Snake venom is produced by glands below
the eye (the mandibular glands)and delivered
to the victim through tubular or channeled
fangs.
 Proteolytic-venom that dismantles the
molecular structure of the area surrounding
and including the bite.
 Hemotoxic-venoms that acts on the heart
and cardiovascular system.
 Neurotoxic-venom that acts on the nervous
system and brain.
 Cytotoxic-The venom has a localized action
at the site of the bite.
 The purpose of venom is to help the snake
defend its self, help it catch prey , and to
help with digestion

7. Black Mamba
