The #DesigningTheFuture3 expedition, led by Dr. Karen Osborn from the Smithsonian National Museum of Natural History, is utilizing novel technologies mounted on ROV SuBastian and within the onboard labs of R/V Falkor (too). These tools include EyeRIS and DeepPIV from the MBARI Bioinspiration Lab. These advanced imaging systems allow scientists to create detailed portraits of animals in their natural environment. Our lab took part in this expedition, working in the onboard laboratory as part of the OceanShot effort.
Have you ever encountered a jellyfish while walking along the beach, been captivated by their translucent beauty at an aquarium or maybe felt the stinging sensation of their venom while swimming or snorkeling in the sea?
I was fascinated by jellyfish during my first visit to Monterey Bay Aquarium (California USA), which has led to a life-long pursuit of studying these amazingly diverse and complex aquatic organisms. My travels have taken me around the globe, introduced me to the world’s leading researchers and further developed my passion for jellyfish research. Now as a Professor of Applied Marine Biology at Tohoku University (Sendai, Japan), I have the privilege of training the next generation of leaders who will carry this scientific field into new frontiers.
For those of you interested in learning more about jellyfish and my research collaborations, I hope you will find the information here both interesting and useful. If you are a student please consider studying Applied Marine Biology in my International Marine Sciences Laboratory at Tohoku University in Sendai, Japan. The ocean awaits, Meet the Lab!

New Lab Publication, Led by Dr. Jimena Garcia-Rodriguez Cubozoa, a relatively small class within Medusozoa (Cnidaria), is distinguished by its complex sexual behaviors, setting it apart from other medusozoan classes. However, reproductive traits and seasonality remain poorly characterized for many species, largely due to difficulties in obtaining specimens. In this comparative histological study we describe the reproductive tissues (gonads) of males and females at multiple maturity stages across 15 cubozoan species, representing two orders, seven families, and eight genera. We document several reproductive traits: (1) variation in oocyte shape, including polygonal oocytes; (2) unidentified cytoplasmic inclusions within oocytes suggestive of … - New box jellyfish name warns of ‘death from behind’ -popsci.com-
The new article from -Pooular Science- foucus a litle more at the Chironex gender and its facinating features like its swimming abitity and its complex eye organs. “Canals or not, they are remarkable creatures. The vast majority of jellyfish don’t rely on vision and passively float in ocean currents, but members of the Chironex genus do not. Instead, they have evolved complex eye organs that help them locate prey. They then use that same musculature supported by the perradial lappets to actively swim through the water towards its target.” Read their full article here: Read the full scientific paper here: - Highly Venomous Box Jellyfish Species Found Off Singapore Waters -wakeup.sg-
The new discovery is raising concerns in Singapore. Several news articles have surged since the announcement. Wake Up Singapore’s coverage focuses on concerns about a perceived shift in box jellyfish populations across Southeast Asia and their potential danger to swimmers. The article also focuses on the naming of the new species: Chironex blakangmati, named after the island’s historical Malay name, Pulau Blakang Mati, meaning “Island of Death Behind.” It becomes the fourth known species in the deadly Chironex genus, a group of jellyfish whose stings can be fatal within minutes.

The discovery of a new box jellyfish species in Singaporean waters is making headlines in Singapore! A news article from the Singaporean news outlet The Independent Singapore, written by Jewel Stolarchuk, covers the fascinating history behind the finding of this new species. It details how a long-standing case of “mistaken identity” was finally resolved through DNA analysis and morphological distinction. The new species initially closely resembled Chironex yamaguchii—a jellyfish Dr. Cheryl Ames had previously discovered in Okinawa during her master’s studies. “But we realized they were completely distinct,” said Dr. Cheryl Ames.
