Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized by bipedalism and large, complex brains.
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head.
The most poisonous spider in America is the black widow and the most poisonous spider in the world is the Brazilian Wandering Spider.
Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis).
They are very intelligent reptiles. Just like the shark, you go into their territory or you do something that provokes them. These large reptiles have lived for millions of years.
The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, the species typically does not actively seek out and prey on humans.
