Researchers from Berhampur University, located in Odisha, India, have recently made a significant contribution to the understanding of global marine biodiversity with the discovery of a new species of marine amphipod. This new species has been christened Demaorchestia alanensis, following its discovery in Chilika Lake in Odisha.
Increased Global Species Count in the Demaorchestia Genus
The discovery of Demaorchestia alanensis is not just noteworthy in itself; it also plays a role in broadening the knowledge regarding the Demaorchestia (Senticaudata, Talitridae) genus. This new discovery brings the total number of identified species in this genus to six. The fact that all these diverse species are found in the same region underscores the rich marine biodiversity of the area.
Characteristics of the New Amphipod Species
Demaorchestia alanensis is easily identifiable and distinguished from other similar species by its unique physical features. It possesses a white hue and measures less than 15 millimetres in length. One intriguing aspect of this amphipod is its 13 pairs of legs each serving a different function.
What truly sets this new marine species apart from others in its family, however, is the two to three hair-like structures found on the front edge of the gnathopod’s propodus – otherwise known as the limb. This is a distinguishing characteristic that researchers have noted in their findings.
Inclusion in the Subfamily Platorchestiinae
The newly discovered Demaorchestia alanensis is a part of the subfamily Platorchestiinae. This subfamily is mainly found along the coast of India, adding further to the country’s rich marine biodiversity.
The Role of Amphipods in the Environment
Amphipods play a crucial role as environmental indicators. They can provide important information about the impact of climate change and the overall health of coastal ecosystems. Scientists can use these creatures as a tool to monitor and assess environmental conditions and changes over time.
Talitridae: One of the Oldest Amphipods Group
Amphipods from the family Talitridae, which includes the newly discovered Demaorchestia alanensis, are among the oldest group of amphipods known to science. Fossil evidence suggests that this family has been present on Earth since the Jurassic era. This makes the discovery of a new species within this group all the more fascinating, contributing not only to our understanding of current biodiversity but also providing insight into the evolutionary history of these remarkable creatures.
