Deep-Sea Surprises: Lantern Shark and Porcelain Crab

Researchers discovered two new species of deep-sea animals: a porcelain crab and a lantern shark. They made these discoveries using specimens collected during a 2022 expedition aboard the CSIRO research vessel (RV) Investigator. Various study teams documented the results in publications released in September 2025. In addition, they named the West Australian Lanternshark and the new Porcelain Crab species after these discoveries.

During an upcoming expedition on RV Investigator, the Commonwealth Scientific and Industrial Research Organization will survey the deep-sea biodiversity of the Coral Sea Marine Park for Parks Australia. Several researchers expect to discover new species.

The West Australian Lanternshark grows to a maximum length of only 407 millimeters. It inhabits the deep oceans. This shark has a thin body and two small dorsal fins, each capped with a sharp spine. It has large eyes which are adapted to the darkness of deep waters.

On the other hand, the Porcellanella brevidentata has length of around 15 millimeters. Its color is an opalescent hue that is somewhere between white and golden. Consequently, it is able to conceal itself behind the white leaves of its sea pen host because to this adaptation.

Hai X. L., Bonnie Y., Yi-Xuan Li, Yi-Tao Lin, Andrew M. H., Zhi Wang, Marissa M., Jian-Wen Qiu conducted the study and published it unde rthe title “Integrative Phylogenetic and Morphological Analyses Reveal Two New Species of Porcellanid Crabs and Resurrect Porcellanella picta Stimpson, 1858 (Decapoda: Porcellanidae)” in September 2025.

ENTECH STEM Magazine has included this research in its list of the Top 10 Biology Discoveries of 2025.

Potential Benefits of the discoveries of Lantern shark and Porcelain Crab

Biodiversity Conservation and Management

1. The identification of new species can contribute to a better understanding of global biodiversity and also help inform conservation efforts.
2. This knowledge can be used to support the establishment and management of marine protected areas in order to ensure the protection of these newly discovered species and their habitats.

Ecosystem Monitoring and Research

• These new deep-sea species can serve as indicators of the health as well as the stability of their respective ecosystems.
• By monitoring the populations and distribution of these species, researchers can gain insights into the overall conditions of the deep-sea environments, which can inform policy decisions and guide future research priorities.

Bioprospecting and Biotechnology

• The discovery of new species, particularly in the deep-sea, may uncover novel biological compounds or adaptations with potential applications in the fields of medicine, agriculture, and industrial processes.
• This bioprospecting approach can lead to the development of new drugs, materials, or biotechnological solutions that can benefit various aspects of daily life.

Educational and Outreach Opportunities

• The fascination with new species discoveries can be leveraged to engage the public, particularly students, in learning about marine biology, biodiversity, and the importance of scientific exploration.
• Incorporating these findings into educational curricula and outreach programs can not only inspire future generations of scientists but also raise awareness about the value of protecting the world’s ecosystems.

Potential Educational and Career Opportunities

I have completed my Master’s in Zoology and am a passionate, curiosity-driven science enthusiast aiming to transform complex scientific ideas in a manner that are easy to understand hence, educate, and inspire.

My journey began with an inherent fascination for understanding how life works at the molecular, cellular, and systemic levels. Over time, this curiosity expanded into a desire to share that understanding with others through clear, engaging communication.

I have an experience of working on the projects in the field of Entomology which has provided me hands-on experience with various research techniques. Besides, I have also gained experience of lab work as well as developed communication skills during the course of my bachelors and masters.

With a strong foundation in life sciences and a growing interest in Medical and Biological research, I have cultivated a writing style that merges scientific facts with creativity.

My experience in teaching has also taught me has also taught me to develop an understanding of what are the interests of people and how to communicate them effectively.

I am also committed to lifelong learning, actively engaging in Interdisciplinary learning, so as to broaden my perspective.
