Bioluminescence

Bioluminescence Tatiana Spanu

The Deep Sea Anglerfish (Melanocetus johnsoni)

• developed symbiotic relationships with bioluminescent bacteria

Hawaiian Bobtail Squid

(Euprymna scolopes)

• The squid collects bacteria from its environment very shortly after it is born.

• The bacteria settle in the light organ of the squid, which produces a controlled bioluminescence while the squid hunts at night.

Alarm jellyfish (Atolla wyvillei)use their bioluminescence to "scream" for help

Ctenophora

• possess green fluorescent protein and a photoprotein (protein that gives off light)

• Proteins from this sea jelly are studied for use in early detection of cancer.

• Only adult females glow, to attract the flying males

• Once a female glow worm has mated, she turns out her light, lays eggs and dies

Communicate with light

Luminescent Panellus (Panellus stipticus)

The luminescence is localized to the edges of the gills and the junction of the gills with the stem and cap

The whole mushroom doesn't glow — only the gills do so.

Jack-O-Lantern mushroom (Omphalotus olearius)
