To create their entrancing light displays, cypridinid ostracods expel a bit of mucus injected with an enzyme and a reactant, and then swim away from the glowing orb to repeat the act again. The result is a trail of fading ellipses, or will-o’-the-wisps hanging in the water column. And the length of each of these pulses is a major component of the courtship display. Some are quick like an old-fashioned flashbulb, said Hensley, while others linger in the water.

Eyes detect light and convert it into electrochemical impulses in neurons. The process is the precursor to vision in complex beings. Yet some simple organisms, such as jellyfish (cnidarians), also have many types of eyes that use the same photoreceptive proteins, called opsins, as animals like flies and humans.

When you’re a firefly, finding “the one” can change the world.


A new study by UCSB evolutionary biologistsTodd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates via bioluminescent courtship, sexual selection increases the number of species — thereby impacting global diversity. Their results appear in the journal Current Biology.

The octopus has a unique ability. It can change the color, pattern and even texture of its skin not only for purposes of camouflage but also as a means of communication. The most intelligent, most mobile and largest of all mollusks, these cephalopods use their almost humanlike eyes to send signals to pigmented organs in their skin called chromatophores, which expand and contract to alter their appearance.

New research on bioluminescent ostracods shows how tiny crustaceans are helping scientists to understand evolution by sexual selection.

Last summer, both Andrew Swafford and Emily Ellis mentored high school students in the Research Mentorship Program.

Research conducted by UCSB scientists shows that the evolution of complex bioluminescent traits may be predictable.

A longstanding question among scientists is whether evolution is predictable. A team of researchers from UC Santa Barbara may have found a preliminary answer. The genetic underpinnings of complex traits in cephalopods may in fact be predictable because they evolved in the same way in two distinct species of squid.

Graduate student Des Ramirez walked away with the lab NCAA bracket challenge, scoring a 96.4% over runner-up, sixth grader, Ian Oakley. Des presciently,nay prophetically chose Big 10 teams like MSU and WI to go deep into the tournament. Second place finisher Ian got off to a good start in the first round, but consistently lost ground after that. Third place finisher and professor Todd Oakley had his brackets completely busted early on when his alma mater, Duke, were knocked out in the first round. At least he filled a bracket, unlike anyone else in the lab.
