Researchers in Japan have officially recognised a new amphipod species, Melita panda, which features black-and-white coloring resembling a panda. Discovered in Japan’s coastal waters, the species has now been classified through detailed morphological and genetic research by Hiroshima University’s team, as published in ZooKeys. The identification of Melita panda underlines the need for continued taxonomic studies to support biodiversity conservation efforts.

New Discovery in Coastal Biodiversity

Originally found in Wakayama Prefecture during the 1990s, Melita panda was re-evaluated as part of a broader study on amphipods, a group of small, shrimp-like crustaceans found worldwide. Professor Ko Tomikawa and colleagues from Hiroshima University note that many marine species in Japan remain unclassified, hindering conservation efforts. Their study highlighted that species diversity in Japan’s coastal areas requires continued investigation to understand the full spectrum of local biodiversity.

Identifying Melita panda: Genetic and Morphological Analysis

Using DNA sequencing and morphological analysis, researchers identified Melita panda’s distinct black-and-white pattern along with unique physical traits. These include forward-positioned gnathopods (claws) and distinct bristle-like setae, which distinguish it from its closest relatives, Melita nagatai and Melita koreana. These amphipods together form a monophyletic group, meaning they share a common evolutionary ancestor, Melita hoshinoi.

Implications for Conservation and Future Study

The recognition of Melita panda emphasises the importance of taxonomy in conservation. Professor Tomikawa noted that the discovery could increase interest in studying coastal species and contribute to more informed conservation planning. He suggests that further taxonomic studies in uncharted marine regions may yield additional species, potentially enhancing our understanding of marine ecosystem dynamics and supporting conservation initiatives across Japan’s coastlines.
