Photo Fun Facts:
  • It's not much of a mystery how this fish got its name...the formation of the long dorsal and caudal fins resemble a jackknife!

  • This unique shape has an important function...it confuses predators as it appears to be two fish instead of one.

  • These fish are very recognizable with their black and white coloring, however, don't expect to see a big school of them...they typically swim alone.

  • These fish aren't big underwater travelers...they tend to stick around in one place (a coral or rock formation) and swim around in circles!

  • Jackknife Fish feed at night on crabs, shrimp, and worms.

  • This Jackknife was about 7 inches in length.

  • Michael photographed this fish at a depth of about 40 feet during a night dive.
