Since the launch of MV's Field Guide app for Apple mobile devices, we've received hundreds of requests for an Android version, my favourite being:


All I want for Christmas is an update on the Android field guide!

Well – drumroll – it's here!

Last Friday, we were very proud that Senator The Hon Don Farrell, Minister for Science and Research and Minister Assisting for Tourism, was able to join us at Melbourne Museum to celebrate this significant milestone.

Development of the Android version is part of a wider project, funded by the Australian Government under the Inspiring Australia, Unlocking Australia's Potential scheme, where we are working with museums around the country to deliver field guide apps for all States and Territories.

The MV Field Guide app is now available through Google Play for Android devices – including tablets, phablets and phones. And it's free.

The app contains over 730 Victorian animals, including mammals, birds, reptiles, frogs, fishes and marine and freshwater invertebrates. Each detailed description includes stunning images, distribution maps, endangered status and animal sounds (for birds, frogs and other noisy critters).

Apple device users will be able to download an updated iOS version in the coming weeks. The new version represents a significant upgrade to the existing iOS app.

Additions to the new Android app (and coming soon for Apple devices) include:

  • Over 30 new species (many added as a result of user requests), including the Great White Shark, the Giant Gippsland Earthworm and Victoria's bird emblem, the Helmeted Honeyeater
  • New marine mammals: seals, dolphins, whales
  • 75 new bird calls, including the Powerful Owl, the Little Penguin, the Tawny Frogmouth, the Sacred Kingfisher and the Red-tailed Black Cockatoo
  • The complete set of frog calls
  • The updated Victorian Endangered Status for all vertebrate species (bringing the app in line with the DSE's 2013 Advisory List for Threatened Vertebrate Fauna)

To celebrate the upcoming release of the Android version of the MV Field Guide app, we're adding a suite of new species; species that have been specifically requested by the users of the existing iOS app.

However, we were missing images of a few species, including Victoria's bird emblem the Helmeted Honeyeater. With no images, these species were going to be left out of the app.

So we asked our MV Blog readers for help – and the response was overwhelming!

Thank you to everyone who sent in images for our MV Field Guide photography competition. We wanted to include them all, but we had to be mindful of download size (with over 700 species in the app, that's a lot of pictures).

The winning photographers were:

  • Neville Bartlett
  • Leo Berzins
  • Arthur Carew
  • Micha Jackson
  • Gordon Slater
  • Ian J. Wilson

Thanks to these people, the upcoming Android version of the MV Field Guide (and the iOS upgrade) will include the Helmeted Honeyeater, the Diamond Firetail and the Little Eagle (along with 25 other new species).

Haven't got the MV Field Guide app? Download it for free from the App Store. Android users, stay tuned – it's coming soon!

UPDATE: The Android version is now available from Google Play. Hooray!

If you're looking for Victoria's bird emblem, you won't find it in Museum Victoria's Field Guide to Victorian Fauna app.

The app contains over 700 Victorian species, but the Helmeted Honeyeater isn't one of them. Why not? We don't have a picture of one.

Museum Victoria is almost ready to launch the MV Field Guide app on the Android network – we just need a few final images. Can you help?

If you have a photograph of any of the species below, send it to discoverycentre@museum.vic.gov.au. If we like it, we'll give you a double pass for our museums and a $30 gift voucher for our museum shops. You'll also be credited as the image's photographer (and get your name in the MV Field Guide app).

  • Helmeted Honeyeater Lichenostomus melanops cassidix
  • Diamond Firetail Stagonopleura guttata
  • Plains Wanderer Pedionomus torquatus
  • Little Eagle Hieraaetus morphnoides

Coloured diamonds

Your Question: How do diamonds get their colours? What's so special about the pink ones?

Diamonds are made up of carbon atoms arranged in rigid tetrahedrons (triangular pyramids).  Pure diamonds are transparent and colourless. They are very rare and therefore very valuable.

Most naturally-coloured diamonds are created when trace elements interact with the carbon atoms during the diamond's creation. The presence of chemical elements such as nitrogen, sulphur, and boron can colour diamonds in shades of yellow, green and blue.

Pink diamonds, however, are a different story.Trace elements have never been found in pink diamonds. Instead, the colour is caused by a distortion in the diamond's crystal lattice, created by intense heat and great pressure from all directions (non-isotropic stress) after the stone's formation in the earth. This distortion displaces many carbon atoms from their normal positions and alters the qualities of light reflected by the diamond. It is this special configuration of the molecules that allows us to observe the stone as pink.

Although pink diamonds are found throughout the world, pink diamonds from the Argyle Mine are said to have the finest colour of fancy, intense pink (colour saturation). This is because Argyle pinks possess densely-packed graining planes that emanate pink colour (twinning lamination). In contrast, non-Argyle pinks have few and indistinct pink graining and are therefore generally lighter in colour. The pink graining in Argyle stones is sometimes visible to the naked eye.

Pink diamonds are not just special because of their structure; they're also incredibly rare: for every one million carats of diamond produced at Argyle, only one carat will be of high-quality pink colour.

The largest pink diamond ever found in Australia is the Argyle Pink Jubilee diamond (8.01 carats). It was donated to Museum Victoria by Rio Tinto and is currently on display in Melbourne Museum's Dynamic Earth exhibition.

Moon gazing across the globe

Your Question: How can my wife and I gaze at the full moon together, but from opposite sides of the globe?

Our enquirer is in Jervis Bay, on the East Coast of Australia. His wife is in Ottawa, Canada. They contacted Museum Victoria to ask if we can help them plan a romantic evening – a full Moon-gazing date on opposite sides of the Earth.

The next full Moon will occur on the 1st or 2nd of August 2012 (depending on what time zone you are in). In Ottawa, the Moon will rise at 7:55pm EDT (Eastern Daylight Time) on 1 August. It will be at its absolute fullest at 11:27pm and will continue to be visible until it sets on 2 August at 6:28am.

Sadly in Jervis Bay's time zone, the full Moon will occur when the Moon is not visible from that side of the Earth, at 1:27pm AEST (Australian Eastern Standard Time). The Moon will have set that morning at 6:24 and will not rise again until 5:32 that evening.

All is not lost, however. The Moon-watching date can still occur, just not at the precise moment when the Moon is at its fullest. Our couple will just have to wait a few hours.

When the Moon rises on the night of 2 August in Jervis Bay (at 5:32pm AEST), it will be 3:32am in Ottawa (EDT). The Moon will be visible in both places and will remain so until it sets in Ottawa at 6:28am (EDT). This means our two Moon-gazers can watch the still-very-full Moon "together" for nearly 3 hours.

If the idea of getting up so early diminishes the romance from the Canadian perspective, our Moon-gazers can wait a few days – if they are happy to look at a Moon that is no longer full.

On 4 August, the Moon will rise in Jervis Bay at 7:38pm (AEST). It will be 6:02am in Ottawa (EDT). The Moon will be visible in both locations until it sets in Ottawa at 8:48am. Unfortunately this means the Canadian half of our Moon-gazing couple will be looking at the Moon during daylight (the Sun will rise in Ottawa on 4 August at 5:51am).

While arranging this date was tricky, it was only possible because our lovers are not on exactly opposite sides of the Earth. If they were, there would be no chance of viewing the Moon that the same time (for more than an instant and only then if they had a perfect view of the horizon). And one of them would have to be in a boat. Less than 4% of all land on Earth (and no part of the Australian mainland) is antipodal (diametrically opposite) to land: the antipode of Jervis Bay is in the North Atlantic Ocean; the antipode of Ottawa is in the Indian Ocean.

The biggest whale

Your Question: Is the Whale Shark the biggest whale in the sea?

Whale Sharks are certainly big. The largest recorded was over 12 metres long!

But Whale Sharks are not whales; they're sharks – the largest shark in the sea. Twelve-metre sharks might sound terrifying, but Whale Sharks are filter feeders. They eat plankton.

The Whale Shark is not, however, the largest shark that ever lived. That was Carcharocles megalodon, popularly known as the Megalodon. Fossils indicate that this species grew to 16 metres long. Unlike the gentle Whale Shark, Megalodon was the stuff of nightmares. A formidable hunter, Megalodon had the largest teeth of any shark, immensely powerful jaws and enormous speed. Thankfully, Megalodon lived 28 to 1.5 million years ago.

The now extinct <i>Carcharodon megalodon</i> had the biggest teeth of any known shark species. Palaeontologists have found fossil Megalodon teeth that are 18cm long!

The largest whale in the sea is the Blue Whale, Balaenoptera musculus. They are truly enormous. There is a complete skeleton of a Blue Whale on display at the Melbourne Museum. It's a whopping 17.2 metres long, but that's actually not that big in Blue Whale terms.

Melbourne Museum's Blue Whale is a Pygmy Blue Whale (the smallest of the three subspecies of Blue Whale) and it's not fully grown. It's only about half the length of the longest Blue Whale on record, which measured 33.58 metres! That is about as long as a Boeing 737 jet aeroplane. This not only makes Blue Whales the largest whales in the sea; it makes them the largest animal that ever lived!

Sharks and whales are very different creatures. Sharks are fish; most are ectothermic ("cold-blooded") and breathe underwater through gills. Whales are mammals; they are endothermic ("warm-blooded"), breathe air and feed milk to their young. Blue Whales, like (almost) all mammals, give birth to live young – the biggest babies in the world. A newborn Blue Whale is as big as an elephant!
