Prof Helps Discover Ghost Shark

Dr. Dominique Didier, a biology professor at Millersville University, has played a key role in the discovery of a new ghost shark species, Harriotta avia. The discovery was announced in a recent paper published in the journal Environmental Biology of FIshes.

Didier, who is considered the world's leading expert on chimaeras which are more commonly known as ghost sharks, has been studying these captivating creatures for decades. She was involved in the discovery of Harriotta avia while working on a book about ghost sharks with three other experts.

"While working on the book, we realized that we had previously unrecognized diversity among the members of the genus Harriotta," says Didier. "I have examined huge numbers of ghost sharks and have an extremely large database on all ghost shark species. Brit Finucci, the lead author on the paper, had access to newly collected specimens of Harriotta from New Zealand, which allowed us to compare and contrast these specimens with other known species."

Didier's expertise in chimaeroid taxonomy has been instrumental in the discovery of numerous new species. In fact, she has named or co-named over 30% of all known species in the Order Chimaeriformes.

"Discovering a new species is a rare and exciting event," says Didier. "It's a testament to the diversity of life in our oceans, and it highlights the importance of ongoing research and exploration."

Didier's research on ghost sharks has not only contributed to our understanding of these mysterious creatures, but it has also inspired students at Millersville University. She has taught ichthyology (branch of zoology that deals with fishes) courses and has mentored undergraduate students who have assisted with her research.

"I encourage students to pursue their passions and to explore the many wonders of the natural world," says Didier. "There are still so many undiscovered species out there, and I hope that my work will inspire others to continue the search."

Fun fact: On September 26, Stephen Colbert from "The Late Show with Stephen Colbert" featured the discovery of Harriotta avia (the ghost shark).
