Friday Fish TimePosted: September 28, 2012
Did you know that only five days ago we celebrated the spring equinox? As ‘science types’ we all know that an equinox occurs twice a year, when the Earth’s poles are the same distance from the sun. Significantly, it marks the start of the best time of the year, in my humble opinion, with longer, warmer days leading in to summer.
Which got me thinking about hot gas and that big ball of it that makes living in Sydney so worthwhile for the next six months – the Sun. I therefore present the Ocean sunfish.
Mr Mola mola is the heaviest known bony fish in the world and the average adult weight is.. wait for it… 1,000 kg. They have an amazing body for a fish - a head and a tail with the main body flattened laterally. Their diet consists of only jelly-fish, which they consume in vast quantities. Females of the species can produce more eggs than any other known vertebrate.
They are native to the temperate and tropical waters of every ocean in the world. Spotting them off our coast may be difficult though, as they spend most of their time hanging out at depths greater than 200m.
And besides, you may get a little shock if one of these guys simply meandered up to you out in the deep blue…
