After a spectacular 4+ weeks in Australia it's time to say goodbye to all the wonderful people I've met and all the beautiful sea life I've observed.

I'm looking forward to applying what I've learned while in Australia back at the New England Aquarium and hope that through the continued work of those in Australia and in aquariums around the world we will soon unravel some of the mysteries that still surround these iconic creatures.

Now, I think it's best to end by letting the pictures and videos speak for themselves.

I spent my last two dives in Australia searching for leafy seadragons, but unfortunately couldn't find any. Regardless, it was good to see the diverse types of habitat that leafy sea dragons typically use and how these are comparable and different to what weedy seadragons prefer. For example, leafy seadragons tend to hang near these long pieces of algae above large mats of sea grasses whereas the weedy's I saw tended to preffer to be where the sandy patches meet the sea grasses.

As I previously mentioned, regardless of whether or not you see seadragons the diving here is always spectacular.

The temperate waters of southern Australia may not get the recognition that the tropcial reefs like the Great Barrier Reef does, however, the colors and diversity of fish, invertebrates, and algaes are absolutely magnificent.

I headed to a new location along the South Australian coast with a local expert to see if I could find some more leafy sea dragons. Unfortunately, the first dive of the day yielded no leafy seadragons, but we were able to spot two other syngnathids--This short-snouted seahorse (Hippocampus breviceps) and this pipefish

I did a night dive at a spot that is renowned for its spectacular nocturnal species and I wasn't disappointed. It was likely one of the most spectacular dives of the trip. I saw striped pyjama squid (Sepioloidea lineolata).

There were lots of hatchling blue ring octopus (Hapalochlaena lunulata) that were likely only a few days old.

and this pipefish hiding in the grass.

I went out for another dive in search of leafy seadragons and lucked out as we spotted four throughout the dive. Two were juveniles (probably 1 - 1.5 year olds) and two were adults.

One was even a large male with eggs on its tail.



It's quite remarkable to see how thick the males tail gets when it has eggs (even wider than the male weedy seadragons), and how many eggs it can hold (anywhere from 150-300 eggs).

Leafy seadragons are exceptionally well camouflaged and look so much like a floating piece of algae when they swim that I've heard stories here of how divers have missed them as they swam right in front of their mask. As you can imagine spotting them is much harder than finding weedy sea dragons.



Even without seeing dragons the dive was exceptional with a rich array of colorful and beautiful fish and inverts like this orange biscuit star (Pentagonaster dubeni) and this moonlighter (Tilodon sexfasciatus)

Since I'll be away for the next few days hunting for leafy seadragons along the coast of South Australia I likely won't have access to email so it may be a day or two until you hear of my journeys.

So, I thought this might be a good opportunity to show you some photos of the interesting, head scratching, thought provoking and down right humours things I've come across while down under ... while both above and below the water. Hope you enjoy.

For being such an iconic and extraordinary looking fish, our knowledge about seadragon life history is surprisingly limited. This is largely a result of their cryptic nature. You can imagine trying to undertake something as simple as trying to do a census to understand how many dragons there are in a given area.

Just spotting a cryptic species like a seadragon is a challange (just look at the photos above) let alone making sure that you get an accurate count of all the animals living in a given area.

Several years ago there was a program called Dragon Search (which we highlighted on one our graphic panels adjacent to our exhibit at the aquarium) that employed the help of local divers and beach goers to report seadragon sightings. While this wasn't a "scientific" assessment it did provide lots of valuable information about what habitats, depths, and locations sea dragons were being found in and what times of the year eggs were being seen and where/when juveniles were being spotted.

After this program ended there was still interest about reporting sea dragon sightings and the program still continues under Reef Watch's Feral or In Peril program. All the information gathered from Dragon Search has now been compiled and can be accessed through the Reef Watch website.

If you're interested in learning more I urge you to check out their website for more information.

I got to do my first dive in South Australia today. Unfortunately the visibility was pretty bad do to a fairly strong swell and therefore there was little chance of finding a leafy sea dragon. It was still quite a fun dive though and I got to see several interesting fish and invertebrates like this old wife:



And this bullseye:


In the evening, I gave talk sponsored by Reef Watch entitled, "In Search of Dragons." I talked a little about the New England Aquarium, our seadragon exhibit, and the efforts that many public aquariums are taking to breed sea dragons in captivity (a very big challenge at this point in time, especially since there are still many holes in our knowledge about seadragons). The talk went well and nearly 40 people attended. The attendees were a good mix of local divers interested in seadragons to local marine biologists who were quite knowledgable about sea dragons.



Tomorrow I'm off to do a dive at a place that is a pretty reliable leafy seadragon site (fingers crossed). Then I'm off to spend the weekend diving in search of leafy sea dragons and some other unique syngnathids that are native to South Australia.

Jeremy

I arrived in Adelaide, South Australia to a leafy seadragon reception at the airport. I spent my first day here at the Reef Watch Marine Creatures Expo.

Reef Watch is a community based monitoring program that utilizes "citizen scientists" to do systematic surveys at local reefs and intertidal areas to assess the health of these rocky reefs and contribute to adaptive management of the local coastal areas (similar to the Great Annual Fish Count that Aquarium divers reported on here).

In addition, they play a vital role in educating and engaging the public about the bounty and beauty of the South Australian marine environment. This expo was a way for them to let the public know about the important programs they're working on and to expose people to South Australian marine creatures and some of the marine scientists that research them.

The expo was broken into several stations detailing their programs on invasive/feral species, in peril/'of concern' (or rarely seen species such as leafy seadragons), and showcasing the diversity of local invertebrates, fish, and algae.

Overall, it was a very informative day and I learned a lot about the beauty of South Australia's temperate reefs.

I'm looking forward to experiencing more of it first hand in a couple of days when I do another dive.

I spent the last couple days exploring the majestic natural beauty of Tasmania as well as learning about some of its unique animal life.


Overlooking Tamar River (Photo: Jeremy Brodt)

I took a walk at Cataract Gorge

Spent some time walking around Dove Lake near Cradle Mountain.

I also visited the Platypus House which in addition to displaying everyones favorite egg laying mammal, conducts research on a particularly devastating fungus that has ravaged the platypus population in Tasmania.

I also got an up close experience with another monotreme when this echidna had a seat in my lap after I sat down to get a picture.

And what trip to Tasmania is complete without seeing the infamous Tasmanian devil.

It's now time to say goodbye to the beautiful state of Tasmania and head to Adelaide, South Australia where I will meet with members of the conservation group Reef Watch and conclude my trip with some diving to see the magnificent leafy sea dragons.

Jeremy

I went out and did another dive today, although this one was in a rocky pool. All my training looking for the cryptic seadragons is paying off since I'm now more a tuned to cryptic species like tiny thornfish.


Thornfish photo (Photo: Jeremy Brodt)

I also spotted this swimming anenome. At night these agile anemones move high up on the plant and extend their tentacles to catch floating prey and during the day they collapse and looks like a sack of beans.


Swimming anemone photo (Photo: Jeremy Brodt)

Like many of the dive sites where I saw seadragons, this dive location was also teeming with mysis shrimp. These tiny shrimp are primary diet of sea dragons and a popular food item for many other fish as well. In this video you can see hundreds of little mysis shrimp (all the white specks) swimming in the water column.



Speaking of tasty things, I spotted this rock lobster hiding in the boulders.

Today I visited a small aquarium called Seahorse World located in Beauty Point, Tasmania. They display over seven species of seahorses in addition to other local fish and invertebrates, and actively breed thousands of pot-bellied seahorses for research.

I also got the chance to do a dive to see a deep water temperate reef that was very similar to the habitat that we display our sea dragons in at the aquarium. The invertebrate life was pretty spectacular. There were loads of sponges and ascidians in addition to hundreds of butterfly perch and southern hulafish. Both species of fish we currently display in our exhibit. It was difficult to get a good photo of the general habitat since it was relatively dark and the visibility was low, but I was able to snap a shot of this cool little nubibranch and ocellata sea star.

I did my last dive with weedy seadragons today and was once again moved by how amazing and beautiful these creatures are. I am certainly going to miss my daily dives with dragons. It's difficult to describe how remarkable it is to see these creatures in their natural habitat so with that being said I'll leave you to enjoy some of my favorite weedy seadragon photos and videos.

Next stop Tasmania!

Our first dive today wasn't sea dragon related, but we still came across some great animals like this group of spider crabs (there must have been 50 or more on the surrounding stumps) and this soldierfish.

Soldierfish (Photo: Jeremy Brodt)

We did yet another sunset/evening dive in an attempt to catch some weedy sea dragon breeding behavior, but unfortunately the water visibility wasn't very good so it was harder to find dragons. We did find a few, but they often became distracted by our presence and would swim away.

Regardless, the dive was quite eventful thanks to a curious juvenile Australian fur seal that became interested by my presence.




And later in the dive I spotted this common gunard perch.

Even though I've been fortunate enough to see at least a dozen weedy seadragons each dive (starting here, and more here and here), it truly never gets old. Seeing such extraordinary animals in their natural habitat is truly awe inspiring.

On our dive today we were blessed with great visibility and therefore got an even better look at the dragons.


Weedy seadragons (Photos: Jeremy Brodt)

Not only was there an abundance of weedy seadragons, but we also saw a fiddler ray
and some cowfish.

However, my favorite sighting of the day was this snail that was apparently in quite a hurry based on the trail it left behind.

Today I dove at a new location to see seadragons. Although, near the beginning of our dive we came across a stargazer buried in the sand.

And this Forster's leaffish hidden in the weeds.

Then we stumbled upon more weedy seadragons



We did another dive just before sunset and saw lots of seadragons. Nearly all the males we saw had eggs on their tails and there were lots of juveniles that appeared to be popping out of the weeds.

In addition to all the dragons I got lucky and caught this large cuttlefish on video as it was swimming by.
