A to Z Cephalopods: E for Euprymna scolopes (Hawaiian bobtail squid)

Hawaiian Bobtail Squid  (Euprymna scolopes) Facts:

  • This little guy fits in a human hand and is known to be quite laid-back
  • It spends most of the day buried in the sand. At night, it hunts.
  • The Hawaiian bobtail squid has a light organ in its mantle where it houses light-emitting bacteria. This helps the squid camouflage itself at night, because the light will match the level of moonlight that is out. Each morning, the squid ejects most of the bacteria, and during the day, the bacteria multiply again.
