What is biomass
What kind of predator is an anglerfish?
What are the light receptors in eyes called?
What are rods
What does intrinsic bioluminescence mean?
What is chemical reactions under neural/hormonal control
True or False. Bioluminescence can be used in mimicry. Give one example.
True. An example is the sperm whales have white marks around their mouths that mimics the bioluminescence released by smaller fish. When the sperm whale’s prey, the Giant Squid, sees this, it thinks it has found food, so it swims over.
