Vibrio fischeri

Vibrio fischeri is a type of marine bacteria known for its ability to produce bioluminescence, or natural light. These bacteria thrive in ocean environments, often living inside certain marine animals like squids and fish, where they form symbiotic relationships. The bacteria emit light through a chemical reaction, which the host animals utilize for various purposes, such as camouflage or attracting prey. This unique ability to produce light is also used in scientific research to study gene expression and cellular processes, making Vibrio fischeri a valuable model organism in microbiology and biotechnology.
