Why Scorpions Glow in the Dark

The video explores the fascinating world of scorpion fluorescence, discussing various hypotheses and experiments conducted by Carl Clook, a biology professor. It covers the techniques for catching scorpions, the potential reasons for their fluorescence, and experiments testing if it attracts insects. The video also delves into scorpion vision, their ability to detect light without eyes, and the role of fluorescence in their sensory systems.

What tool is used to find scorpions in the desert?

• A magnifying glass

• A metal detector

• A thermal camera

• An ultraviolet torch

Which of the following animals does NOT fluoresce under ultraviolet light?

• Elephants

• Platypuses

• Jellyfish

• Owls

What was the result of the experiment testing if scorpions use fluorescence to attract insects?

• Fluorescent scorpions caught more insects

• Non-fluorescent scorpions caught more insects

• There was no difference in the number of insects caught

• Fluorescent scorpions caught fewer insects

How many eyes do scorpions have?

• Two

• Four

• Six

• Eight

What unique ability do scorpions have regarding light detection?

• They can see in complete darkness

• They are blind and rely on other senses

• They can only see ultraviolet light

• They can detect light with their tails

What is one hypothesis for why scorpions fluoresce?

• To camouflage themselves

• To scare predators

• To detect ultraviolet light

• To attract mates

What is the suspected reason scorpions use their fluorescence as a sensory system?

• To communicate with other scorpions

• To find food during the day

• To avoid predators

• To determine if they should come out at night
