A trip to space !
On April 29th a few baby Hawaiian Bobtail Squid
Mating lasts 30 to 50 minutes and usually happens at night.
The eggs each squid lays are called a clutch. Clutches can have 50 to 200 eggs, and it takes about 30 minutes to lay a clutch.
One of the most amazing things about a bobtail squid is that it can light up!
Bacteria live in an opening at the bottom of the squid's body. When the bacteria have enough oxygen they make a chemical reaction that produces light.The squid knows how much light is needed and controls it by increasing or decreasing the amount of oxygen that goes to the bacteria.
were sent to space to test how low gravity affects beneficial bacteria.The baby squids were sent in tubes of salt water, and since sadly they were meant to die, none made it back alive. After 14 hours the scientists added some bacteria into the tubes. The bacteria had 28 hours to colonize before the squids met their death. Scientists learned good bacteria grow more slowly in space than on Earth.
The Hawaiian Bobtail Squid lives off the Hawaiian Islands in shallow waters in the Pacific Ocean.
