Many organisms have their common names identical to their scientific names. For example, there exist apes of the genus Gorilla known commonly as gorillas, and plants of the genus Delphinium known as delphiniums.
However, are there any examples of the common name of an organism overlapping with the scientific name of another organism, therefore causing ambiguity when the organism's name is spoken aloud? If written with correct formatting, this should not cause a problem in any case, due to the formatting specifically describing a genus/species.
