Get Ready For..Squids in Space!

I would have never guessed that a squid would go up in space before at least myself! Well…here is the lucky squid that get to travel up up and beyond:

SPACE SQUID!

If the final launch of the space shuttle Endeavour happens next week, on-board will not only be human cargo, but baby squid as well! No, these astronauts will not be eating calamari, these squid will be alive and provide a better understanding of bacteria in space (for the sake of us humans).

Bacteria has been studied in space before- but only the bad kind. Salmonella was sent up in 2006 on the space shuttle, and when it returned the bacteria was almost 3 times as likely to kill mice than normal.  E.coli is another example of a bad bacteria which also changes its behavior due to exposure to anti-gravity.

The squid of choice to make this epic journey is the bobtail squid Euptymna scolopes. This Pacific species was chosen particularly because it carries a type of bacteria called Vibrio fischeri in its body.  The bacteria houses itself inside their light organs once the baby squid hatch. The bobtail squid use this light to shine downward so prey/predators don’t see a shadow cast of the outline of the squid from below.

Bobtail Squid- First Cephalopod To Go Into Space

This type of relationship is a great example of mutualism-where BOTH organisms benefit in a relationship. Humans also have mutualistic relationships with bacteria- in our stomach and immune system.

Jamie Foster is the person who is charge of this experiment, hailing from the University of Florida in Gainesville. The experiment will go as follows:

  • Newly hatched squid who have not yet been exposed to the bacteria- will swim around in tubes of seawater while launching into space
  • 14 hours after the launch- an astronaut will release the bacteria into the tubes and allow 28 hours for the bacteria to colonize inside the squids light organs
  • Then, sadly (for research purposes) the squid will be killed and fixed solid-and brought back to a lab on planet Earth for examination
Foster’s preliminary research which mocked micro-gravity appeared to show problems the uptake of bacteria by the squid. Which could ultimately mean that mutualistic bacteria in humans in space could be affected. 
So I will be patiently waiting to find out the results of this study..and hopefully some amazing pictures of baby squid in front of a window with Earth in the background 🙂
