Venom vs. Poison: Venomous animals inject toxins through bites or stings, while poisonous animals secrete toxins that are harmful when touched or ingested.
Intraspecific Competition: Venom can be used not only for defense and hunting but also for intraspecific competition.
Sophisticated Venom Delivery: Some venomous species, like cone snails, have evolved sophisticated methods to deliver venom.
Toxin Diversity and Effects: Venom composition varies widely among species, depending on their prey and diet. Vipers, for example, have venom that disrupts the blood system.
Venom Across Animal Families: Nearly all animal families have at least one venomous member, showcasing the widespread evolution of venom across the animal kingdom.
Speculation on Dinosaur Venom: Some researchers speculate that dinosaurs may have been venomous based on tooth structures resembling those of venomous snakes
Loss of Venom Over Time: Venom production can be energetically costly, leading some species to lose their venom over time if it becomes unnecessary for survival.
