New Damselfish Species Found in Maldives

In December 2024, an extraordinary scientific milestone was achieved in the Maldives with the discovery of a new damselfish species named Chromis abadhah. This groundbreaking finding was the result of an international collaboration of marine scientists, who uncovered the species inhabiting the deep-sea coral reefs in the mesophotic zone of the Maldives. The discovery adds to the country’s rich marine biodiversity and highlights the importance of global scientific partnerships in exploring uncharted marine ecosystems.

Background of the Discovery

• The discovery was made in December 2024 by an international team of scientists.
• The species was found in the mesophotic zone, a region of deep-sea coral reefs in the Maldives.
• It is the first recorded instance of Chromis abadhah anywhere in the world.

Naming and Significance

• Named by the Marine Research Institute as Chromis abadhah.
• The term “abadhah” signifies “perpetual” in Dhivehi, symbolizing the enduring nature of the ocean.
• The naming honors the Rolex Perpetual Planet initiative, which supported the expedition.

Habitat and Distribution

• Recorded in eight different locations spanning 180 km from Lhaviyani Atoll to Dhaalu Atoll.

• Eye Features: Silvery-blue circle surrounding a darker central portion of the iris.
• Scales: Reflective scales below the eyes.
• Preservation Changes: Blue hue fades to reddish-brown when preserved.

Ecological and Scientific Importance

• Expands the understanding of mesophotic zone biodiversity.
• Highlights the need for continued exploration and conservation of deep-sea ecosystems.
• Emphasizes the role of international collaboration in marine research.
