Dusky Whaler juveniles in Sydney 2011

Juvenile Dusky Whalers have once again been sighted in the Shelly Beach/Fairy Bower area of Sydney. Following on from sightings in 2004, 2007, 2008 and 2009, Gaetan Guilhon emailed to say that he had filmed juveniles in the same area on 28 May 2011.  View his embedded video below.

This week in Fish: Moorish Idols and sponge eaters

This week we feature two more movies of Kermadec Islands fishes and we ask the question "Which fishes eat sponges?".

Which fishes eat sponges?

A colleague just asked me this question. I had to confess that I wasn't sure of the answer.

This week in Fish: Back to reality

Returning to work after three weeks on fieldwork is not always easy.  Despite the excellent efforts of Amanda and Sally, there were many emails to answer and plenty of jobs that had to be done.  I have added a number of images and two movies in a feeble attempt to relive the Kermadec experience.

Kermadec wrap-up

Since I last posted to Fish Bits, I have participated in an amazing fieldtrip to the Kermadec Islands. I returned earlier this week and have now resumed adding content to the fish site.

This week in Fish: Baby Batfish

It was another big week with heaps of new fishy content added to the site.  Two of the highlights were the spotting of juvenile Roundface Batfish in Sydney Harbour and the addition of a stunning Halimeda Ghostpipefish image.  Follow the links below to read more about these and other happenings.  This will be the first and last Fish Bits post for May.  I will be participating in the Kermadec Islands expedition (more below) until early June.  Thank you as always to everyone who contributed during the week.

Batfish in Sydney Harbour

Sydney Harbour doesn't immediately spring to mind when you think of tropical fishes. That's why we were recently surprised to hear about juvenile Roundface Batfish that have been seen near Clifton Gardens and in Parsley Bay, in the outer harbour.

Shark blood production

In what part of the body is a shark's blood made? This was the subject of an enquiry that was recently sent to the Australian Museum.

This week in Fish: Pineapplefish and Surf Sardine

It was a short but action-packed week.  The highlights were adding an image of the Whale Shark sighted last week in Botany Bay and a movie of dolphins (I know they are not fish) off Manly.  Thanks to everyone who contributed.

Dolphins at Manly

Swimming with dolphins has to be high on the wish list for many people.  Gaetan Guilhon had the very good fortune to do just that at Manly Beach, Sydney, on a lovely April morning in 2011.   The footage shows a pod of about 50 Common Dolphins, Delphinus delphis.  Please don't tell me that dolphins aren't fish - I know that!  I was just so envious and excited I had to share this movie.  Enjoy!
