Shrimp can only swim backward.
Shrimp do not have fins to move in the water so they pull in their abdomen toward their body quickly. This motion propels them through the water but because of their configuration it means they are moving backwards.

Fact: Cats can hear ultrasound.
Ultrasound is the frequency of sound waves greater than what the human ear can hear (approximately 20kHz). Cats have an approximate hearing range of 45Hz - 64,000Hz compared to 65Hz - 20,000Hz of a human hearing range.
*Infrasound is any frequency below the average human hearing range.
Shrimps contain red pigments classified as carotenoids which is found in carrots too! A lack of carotenoids in the diet of a zoo-kept flamingo may turn a flamingo white.
