Color-changing cuttlefish




Since I started volunteering at the aquarium, I've been kind of obsessed with cephalopods. This group of animals includes squid, octopuses and of course, cuttlefish. Here are some of the weird-but-true facts about these amazing animals.
  • They can change color and texture rapidly
  • They have three hearts that pump blue blood
  • They have a hard, parrot-like beak that releases venom (not harmful to humans) into prey
  • They have two feeding tentacles that retract into the body and then dart out quickly to capture prey (much like a frog's tongue)
  • Their cuttlebone fills with gas, enabling it to hover
  • They squirt ink to confuse and evade predators
  • And they're ridiculously cute

wow that is pretty amazing. you're learning a lot at your aquarium job which is awesome. you get to see/learn about all the cool animals that i'm sure many people don't know about and that's pretty cool. i can't wait to read more blogs about what you're learning and doing it is an incredible experience.
