This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

This video provides a demonstration of bioluminescent bacteria glowing in the dark.

This animation explores the LUX operon, a set of five genes that are involved in bacterial bioluminescence.

This animation shows how a cell infected by a virus signals cytotoxic T cells to destroy itself.

This animation shows how bacteria can transfer genes to each other.
