Question : Comprehension: Read the given passage and answer the questions that follow.
Migaloo is by far one of the world’s most recognisable whales because he is completely white. Thanks to genetic sampling of Migaloo’s skin, scientists have identified that he’s male, and his albino appearance is a result of a variation in the gene responsible for the colour of his skin. Simply by looking different, Migaloo has become an icon within Australia’s east coast humpback whale population. Indeed, Migaloo has his own Twitter account with over 10,000 followers and a website where fans can lodge sightings and learn more about humpback whales. He was first discovered in 1991 off Byron Bay, Australia, and has since played hide and seek for many years, with many not knowing where or when he’ll show up next. He’s even surprised Kiwi fans by showing up in New Zealand waters. With the last official sighting two years ago, the time has once again come for us to ask: Where is Migaloo? Already this year, there have been false sightings, such as a near-white whale spotted off New South Wales. To make things more confusing, regular-looking humpbacks can trick whale watchers when they flip upside down due to their white bellies.
