Ever Wonder if Cuttlefish Like to Cuddle?
Learn all about these flashy fish
Cuttlefish are marine molluscs (of the order Sepiida) that belong to the same class as squid and octopus. This class is known as Cephalopoda which means head foot. They have eight arms and two tentacles.
Cuttlefish are experts at disguise and can change color to blend in with their surroundings. The males are also known for their vibrant “flashing” colors during fighting and mating. Cuttlefish are hunters and, in general, they like to be alone.
There are approximately 100 different species of cuttlefish. The species that we have at Discovery Place Science can grow to be about a foot long.

Emotions are complicated. They’re so complicated that scientists still don’t even fully understand them! One thing that scientists do know, though, is that some of our biggest feelings are caused by a tiny part of the brain called the amygdala.
The amygdala is a bundle of important nerve cells deep inside the brain. Everyone has two amygdales—there’s one in each half of the brain. The amygdala works with the parts of the brain that control memory, behavior and emotion, and this tiny group of cells packs a big punch when it comes to emotions, especially stress and fear.
Most people don’t like to feel scared, but humans are fascinated by it! Think of all the spookiness in the month of October. The rush of energy and emotion people get by being scared can be enjoyable in controlled situations, like a scary movie or an amusement park ride.
No matter the source of the scare, the amygdala’s role is the same. The amygdala is like a bridge connecting two very different parts of the brain: the part that controls the body functions you aren’t aware of (like breathing) and the part that “thinks” for you.
This means that when your amygdala gets information that tells you something scary is happening, it can send signals that make your heart race and your breathing get faster, making you feel scared!
