puffadder shyshark

Terms like “shyshark” and “donut” that emerged in response to shysharks’ defensive behavior can be applied to multiple species. To keep this from confounding research, academics use “Happy Eddie” as an easy-to-remember name for puffadder shysharks, based on the scientific name Haploblepharus edwardsii. “Plain Happy,” “pretty Happy,” and “Happy chappie” refer to brown, dark, and natal shysharks respectively.
