Key Differences
Adders, such as the European adder, are adapted to cooler climates and are typically smaller and less aggressive, while vipers, including rattlesnakes and bushmasters, can inhabit a range of environments and often grow larger.
Adders tend to have a zigzag pattern along their back which serves as camouflage in their natural habitat, whereas many vipers have more varied and sometimes vivid colorations that reflect their diverse environments.
The venom of adders, while potent, is generally less toxic compared to that of many vipers, which can be highly lethal and contain enzymes that cause rapid tissue damage.
Adders give birth to live young, a trait shared by some vipers, but many vipers also exhibit diverse reproductive strategies including laying eggs.
Adders have a more limited geographical range, mainly found in Europe and Asia, whereas vipers are distributed widely across the Americas, Africa, and Eurasia.
