New research led by University of Hawaiʻi at Mānoa scientists revealed that, in the mutually beneficial relationship between with the Hawaiian bobtail squid, Euprymna scolopes, and the luminescent bacterium, Vibrio fischeri, an immune protein called “macrophage migration inhibitory factor” or “MIF,” is the maestro of daily rhythms. This activity explores the content presented in the animated video Nature’s Cutest Symbiosis: The Bobtail Squid, which describes how the light produced by bacteria living inside bobtail squid helps the squid avoid its predators. In this short animated film, Ed Yong and scientists Margaret McFall-Ngai and Edward Ruby explain how the Hawaiian bobtail squid recruits a specific type of light-producing bacteria, Vibrio fischeri, to colonize its light organ. Sepiolida are iteroparous and a female might lay several clutches, each of 1-400 eggs (dependent on species), over her estimated one-year-long lifetime. The “Student Handout” probes students’ understanding of the key concepts addressed in the film. The bacteria reside inside a structure on the underside of the squid called the light organ. The bobtail squid is no bigger than a walnut and is a tasty mouthful for predators in the coastal waters of Hawaii. 2.C.2, 2.D.1, 2.E.2, 2.E.3, 3.D.1, 3.D.2, 4.A.5, 4.B.3, IB Environmental Systems and Societies (2017), https://doi.org/10.1371/journal.pbio.1001783, Superbugs That Resist Antibiotics Can Evolve in 11 Days, How Giant Tube Worms Survive at Hydrothermal Vents, Mosquitoes Might Save Lives, Thanks to Bacteria, Microbes from Mom: Vaginal Birth vs. C-Section.

In this short animated film, Ed Yong and scientists Margaret McFall-Ngai and Edward Ruby explain how the Hawaiian bobtail squid recruits a specific type of light … This video is part of the series I Contain Multitudes, hosted by science journalist Ed Yong. The bacteria reside inside a structure on the underside of the squid called the light organ. But the species continues to thrive in these waters in part because of its symbiotic relationship with the bioluminescent bacteria Aliivibrio fischeri (formerly Vibrio fischeri). “Divining the Essence of Symbiosis: Insights from the Squid-Vibrio Model.” Public Library of Science Biology 12, 2 (2014): e1001783. McFall-Ngai, Margaret. The bobtail squid is no bigger than a walnut and is a tasty mouthful for predators in the coastal waters of Hawaii. The light organ provides the squid with a selective advantage because the light from the organ makes the squid virtually invisible to nocturnal predators, while the bacteria benefit from having a home and nutrients. The eggs are covered with sand and left without parental care. Winogradsky Column: Microbial Ecology in a Bottle, Winogradsky Columns: Microbial Ecology in the Classroom. Symbiosis with A. fischeri from the surrounding seawater is initiated immediately upon hatching, and the bacteria's colonisation of the juvenile light-organ induces morphological changes in the squid that lead to maturity. The squid and the bacteria maintain a lifelong symbiotic relationship that benefits both species. McFall-Ngai, Margaret. Please see the Terms of Use for information on how this resource can be used. The “Abbreviated Film Guide” provides a short summary of the film, along with key concepts and connections to curriculum standards. This activity explores the content presented in the animated video Nature’s Cutest Symbiosis: The Bobtail Squid, which describes how the light produced by bacteria living inside bobtail squid helps the squid avoid its predators. Can a Fungus Save Plants from Global Warming. At night, the bacteria produce a glow that matches the moonlight coming from above, rendering the squid virtually invisible to predators from below. A spectacular feature of this symbiosis is that squid aren’t born with a complete light organ—the bacteria help the organ develop. “Divining the Essence of Symbiosis: Insights from the Squid-Vibrio Model.” PLoS Biology 12, 2 (2014): e1001783. The bacteria are essential for the squid to develop its light organ and produce light. McFall-Ngai, Margaret. But the species continues to thrive in these waters in part because of its symbiotic relationship with the bioluminescent bacteria Aliivibrio fischeri (formerly Vibrio fischeri ).
