Scientists have discovered a new species of box jellyfish near Sentosa Island, Singapore. This finding is significant as it reveals a greater diversity of these highly venomous creatures than previously known.
Researchers from Tohoku University and the National University of Singapore identified the jellyfish, naming it Chironex blakangmati. The name reflects the island’s historical Malay title, Pulau Blakang Mati, which translates to "Island of Death Behind." This new species adds to the Chironex genus, which includes jellyfish capable of delivering life-threatening stings.
Initially, the presence of C. blakangmati was not clear. It closely resembles Chironex yamaguchii, documented in Okinawa waters. For years, experts believed they were the same species. Lead researcher Cheryl Ames highlighted the similarity, noting her previous work on C. yamaguchii. However, a deeper examination revealed that they are entirely distinct species.
Genetic analysis clarified the misunderstanding, while a detailed physical study confirmed the new species. The primary distinguishing feature is found in the jellyfish’s perradial lappets, structures at the base of the bell that aid in movement. In C. blakangmati, these lappets lack the pointed canals seen in the other three known species.
This discovery opens the door for further research into the ecology and potential impacts of jellyfish in marine environments. Scientists will investigate the distribution and behaviour of C. blakangmati to better understand its role in coastal ecosystems.
