Black adder may refer to either of two classifications of snake:
- Vipera berus, a venomous viper species found in Europe and Asia.
- Heterodon platirhinos, a non-venomous snake found in the United States.
Famous quotes containing the word black:
“Light thickens, and the crow
Makes wing to th’ rooky wood.
Good things of day begin to droop and drowse,
Whiles night’s black agents to their preys do rouse.”
—William Shakespeare (1564–1616)
