Comments on: Mussels… not your average shellfish! http://www.bay-keeper.com/2009/02/mussels-not-your-average-shellfish/ Say g'day to the Bay Wed, 08 Sep 2010 12:34:22 +0000 hourly 1 http://wordpress.org/?v=3.0.1 By: Nino http://www.bay-keeper.com/2009/02/mussels-not-your-average-shellfish/comment-page-1/#comment-32 Nino Mon, 27 Apr 2009 11:18:53 +0000 http://www.bay-keeper.com/?p=154#comment-32 Gee, that's tough one! There seems to be a few schools (pardon the pun) of thought about Argonauts. In this case I'm pretty sure we're talking about <em>Argonauta nodosa</em>, aka paper nautilus, an octopus-like animal, not one of the Greek heroes who sailed to fetch the golden fleece! It may just be that the one you met did arrive last year. Argonauts are believed to live longer than other octopus species which generally only live for 1 to 2 years. But it's not easy to tell one from another... if you found one in the same place in 2 different years you couldn't really be sure it was the same animal. Apart from that, there are some major changes happening since the Rip was deepened for the Channel Deepening Project in 2008. The tidal currents are now much stronger. We're likely to see a lot of changes in the seasonal movements of bouyant ocean-living species that can get carried into the Bay on the incoming tide, or flushed out on the outgoing tides. There's so much more to enjoy and learn about the Bay. Thanks for sharing your observations with us Alison! Gee, that’s tough one!

This is early for the usual winter influx of argonauts or has it been hanging around the bay since last year's flotilla visited us?

But I think you're mistaking me for someone else. Actually... I'm an OLD PUNK! Thanks for the kind words Karen. But I think you’re mistaking me for someone else. Actually… I’m an OLD PUNK!
