During acclimation, we closely monitor things like temperature, pH, oxygen levels and salinity to make sure our fish stay healthy and to determine when they’re ready to go into their new tank. This basically means that we exchange water from the new tank to the tank or shipping container that the fish is in until both are as similar as possible. Whenever a fish is moved from one water body to another, acclimation must be done. Once we got the animals back to the aquarium (at around midnight!), the real work began. Finally, they repacked her and sent her on another plan from Los Angeles to Minneapolis, and our staff collected her and the rest of the animals at the airport and headed back to Duluth. Customs (just like any other international traveler) and brought her back to their warehouse for a water change and fresh oxygen. So we enlisted Consistent Sea, another fish wholesaler in Los Angeles, to assist us. The large orange-spotted grouper traveled in its own containerīecause the travel time was so long, a water change needed to be performed so that water quality was within safe limits for the shark. She lived at their holding facility for another year, eating and growing like crazy, until we called up Cairns looking for, you guessed it, a Zebra Shark! After working out all of the details, Cairns packed her up, along with the rest of our fish and sent her on her long journey to us.

Now getting back to our shark – she spent the first year of her life growing up at Reef HQ and was then sent to Cairns Marine, a fish wholesaler in Cairns Australia. Our zebra shark is showing a spotted pattern As they reach adulthood, the stripes get replaced by black dots. As they grow older, the stripes fade and they develop a spotted pattern. Zebra sharks have cylindrical bodies which are dark brown in color, covered in yellow stripes. The pups actually have stripes when they’re born (hence the name Zebra Shark). They can be about 8 inches long and Zebra Sharks will lay about four eggs at a time. The eggs are protected by egg cases with hairy-looking fibers all over the outside which help to attach the egg case to corals or seagrass and keep it from floating away. This means the pups develop outside of the body. Our little “pup” (that’s what a baby shark is called) was hatched from an egg after an approximately 4-6 month gestation period. The strong egg resulting in a 30 hatch rate is actually a HIGHER survival rate than if it wasnt as tough, as the egg would have a higher chance at getting eaten by predators. Shark produces enough eggs for a 30 success rate being plenty. Late in the evening of February 4, 2012, a Zebra Shark was born at Reef HQ, a public aquarium in Queensland Australia. Perhaps evolution found the balance between hatch rate and ‘getting eaten’ rate. So you might be wondering, how does a 5 foot long shark get all the way from Australia to Duluth? Well, let’s start at the beginning.
