New Zealand Scientists Discover Rare Ghost Shark Species

September 30, 2024

Scientists in New Zealand have discovered a new species of ghost shark, a rare fish that lives deep in the Pacific Ocean. This discovery is important because it helps us learn more about marine species that are not well-known.

What Are Ghost Sharks?

Ghost sharks, also called spookfish or chimeras, are unusual fish that are related to sharks and rays. They have skeletons made of cartilage instead of bone, and unlike most fish, they don’t have scales.

Where Was the New Species Found?

The new species, named the Australasian Narrow-nosed Spookfish (Harriota avia), was discovered in an area called Chatham Rise, located east of New Zealand. Ghost sharks live in very deep waters, sometimes as far down as 2,600 meters (1.6 miles), which makes them hard to study.

Importance of the Discovery

Dr. Brit Finucci, one of the researchers involved, said this discovery is important because ghost sharks are difficult to find, and little is known about their biology or how many of them exist. Learning more about them can help with conservation efforts to protect these rare creatures.

Naming the New Species

The name Harriota avia was chosen in honor of Dr. Finucci’s grandmother. It also highlights the ancient history of chimeras, which are considered distant relatives of modern fish.

What makes this species different?

At first, scientists thought this ghost shark was part of a species that is found in many places. However, genetic testing showed that Harriota avia is unique to the waters around Australia and New Zealand. Understanding these genetic differences is important for protecting the species.

Studying ghost sharks is crucial for coming up with ways to protect them, especially since they live in such deep and difficult-to-reach parts of the ocean. Knowing more about their population and health will help scientists create plans to conserve them.
