New 'Demon Shark' Species Identified Through Examination of Egg Cases

Scientists have identified a new species of shark, Apristurus ovicorrugatus, through examination of egg cases.
The egg cases were first discovered in 2011 by researcher Brett Human in northwestern Australia.
The species' name is derived from the Latin terms ‘ovi,’ meaning egg, and ‘corrugatus,’ meaning corrugated, which refers to its corrugated egg cases.
The discovery underscores the importance of egg case shape for identifying species and scientists are searching museum collections for more new species.
UK-based Shark Trust has developed a global database that encourages members of the public to upload images of egg cases they find.
