Credit: Kristen KoenigCephalopods, which include octopuses, squid, and cuttlefish, exhibit impressive behaviors such as the ability to quickly adapt their appearance to blend into their surroundings, communicate with one another, demonstrate spatial learning, and use tools to solve problems. Their high level of intelligence even allows them to experience boredom.
This is an example of the live imaging data generated in this paper. The membranes of the cells in the eye are labeled with a fluorescent dye allowing us to visualize individual cell behavior during development. Credit: Kristen Koenig The researchers used similar techniques to those made popular to study model organisms, like fruit flies and zebrafish. They created special tools and used cutting-edge microscopes that could take high-resolution images every ten minutes for hours on end to see how individual cells behave. The researchers used fluorescent dyes to mark the cells so they could map and track them.
