What physical feature gives the Zebra Mussel its specific name?
Answer
Dark, wavy, zigzag stripes on the shells of adults
The designation 'Zebra' in their common name comes directly from the distinctive visual pattern found on the shells of mature specimens. This pattern consists of dark, wavy lines that run in a zigzag fashion across the lighter background of the shell. Although this feature is defining, it is noted that sometimes this patterning can be faint or entirely absent, which complicates identification and can lead to confusion with other species, requiring managers to check other physical markers.
