  1. Yep, part of my research looked at the predation of seahorses and the octopus was found to be a major predator. Dead seahorse number 2 underwater: So finding a dead Hippocampus underwater isn't impossible after all, just incredibly rare!!.
  2. Hmmmmm, and how many times have you found a dead seahorse whilst diving???? In the many hundreds of dives that I have done on seahorses as part of my PhD research I've been lucky enough to find 3 dead animals.... two of them had their heads missing and the other was so decompossed that any analysis on the eye structure would have been impossible!!! And to be honest, given my seahorses managed to survive for at least 4 years I'm pretty sure there eye sight was okay as they obviously hadn't starved to death! As John is aware, I've just finished a study on the impacts of flash photography on seahorses with the results to be published in a journal shortly. cheers, Dave
  3. Alex, The Spotted Handfish in the Derwent estuary in Hobart is regarded as one of Australia's most endandgered fish species. If you are interested in going for a dive on them drop me a PM and I'll put you in touch with someone who might be able to take you for a dive on a small colony of them. I dived it in Winter last year and whilst seeing handfish was fantastic, the 9 degree water wasn't so good! You will need a drysuit if diving in the Derwent! Also, Tinderbox Marine reserve is also a god macro dive just out of Hobart, I had a good dive there several years ago. cheers, Dave
  4. Not sure why they were merged together as A. tentaculata as I can't find a reference for it. There was probably a reason for a species merge on Fishbase however its odd that Kuiter doesn't reflect it in his new book which is the most comprehensive guide to syngnathids, Rudie obviously has his own reason for keeping them seperate. Genetic analysis would provide the most diffinitive answer!
  5. If you follow Rudie Kuiter's new book "Seahorses and their relatives - 2009) the species would be Acentronura brevperula. A. tentaculata is considered to be endemic to the Red Sea whilst A gracillissima is recorded from Japan. I've seen A.brevperula throughout the Indo Pacific and it is very variable in colour.
  6.

  7. It is a juvenile filefish/leatherjacket of some sort. Looks very similar to the pygmy leatehrjacket below that we get in southern Australia.
  8. Hi everyone, I need some help. It was recently brought to my attention a Romanian website that has stolen hundreds of my fish photo's to assist with sales in their aquarium fish business. Basically, about 90% of the fish and invertebrate image on their website have been stolen from my Marine Species database that I set up to help people with ID's: www.speciesspotlight.com This is the offending website: http://www.acvariidevis.ro/pagina/despre-noi Not only are they using my images, they have actually watermarked their website details onto each of my pics!!! This has really p1ssed me off. Some examples can be seen here: http://www.acvariidevis.ro/pesti/serranida.../potato-cod/269 http://www.acvariidevis.ro/pesti/serranida...land-groper/295 http://www.acvariidevis.ro/pesti/gobiidae/...finned-goby/173 The good people on Diveoz.com.au have given me some good advice so far however now I'm stuck. I've sent several emails to the company (office@acvariidevis.ro) and they won't reply. I emailed the company's ISP (http://www.itcnet.ro/) and sent them a 'DMCA Takedown Message' but they also won't reply. Anyone on wetpixel able to offer any more suggestions? Anyone on wetpixel live in Romania and own a baseball bat? thanks, Dave
  9. I was also scratching my head about this one when I first got the housing! To change the shutter speed you enter 'manual' mode and then you must hold down the Canon 'print' button (this is the button on the top left above the control pad). When the print button is held down you can move the left and right control buttons to adjust the shutter speed. Works really well. I haven't used this system with a strobe just yet but all I can say is that using a strobe is only going to improve image quality. I've got a small Ikelite DS51 that I might test out with it. cheers, Dave
  10. The first species is Chromodoris fidelis and the second is Chromodoris geometrica. cheers.
  11. I think it could be the same site, except were we stayed they never referred to it as Mainit Point. But there is a MASSIVE hotel being built there, I wrote a summary of my first dive there in this article which includes a surface shot of the site: http://www.daveharasti.com/Phils09/article/index.html I propose it's renamed to 'Cephalopod Bay' given that I saw 10 different species there in 5 days. I must have been lucky! I've dived it twice a day for 5 days straight last week and didn't see another boat the entire time! So it was still secret last week.... Leslie - Thanks for the Synchiropus kuiteri ID, I just found a shot of a juvenile in Kuiter's World Atlas of Fish and it's identical. Drew - Fish 2 has been stumped. I couldn't see any dorsal fin what so ever, I'll see if Rudie Kuiter recognises it. thanks, Dave
  12. I'm stuck on confirming the ID of the below 3 fish species taken on a recent trip to the Philippines Fish 1: About 2cm in length - Secret Bay - Anilao Fish 2: Some sort of Dragonet about 5cm long. not sure of species - Secret Bay - Anilao Fish 3: Another dragonet, about 1-2cm long - Photographed at Dauin. Is it possibly a juvenile Fingered Dragonet (Dactylopus dactylopus)? Any input appreciated. cheers, Dave
  13. I've just recently returned from Anilao where I had some of my best ever critter dives at Secret Bay. Whilst there, I photographed 6 species of octopus however I can't work out the ID of this species. The occy was pretty small, max length of about 8cm. Anyone know what it is? ta, Dave
  14. Scuba Snoopy Tracks Down the Tiger Tail Scuba Snoopy has a thing for seahorses. Not in that weird sort of fetish way, but more of a fascination for an animal that looks like a scientific experiment between a horse and a dragon that had gone horribly wrong. Plus Scuba Snoopy is bigger than seahorses so they don’t scare him! Scuba Snoopy (aka Snoops) had seen many seahorses in his time, ranging from the huge Pot Belly Seahorse in Australia that was almost as big as him, to the tiny pygmy seahorses in Indonesia that he needed a magnifying glass to see. But there was one seahorse that continued to elude Scuba Snoopy... the mysterious bad @rse Tiger Tail Seahorse of the Indo Pacific that had been avoiding him for many years. Snoops wanted this seahorse... and he wanted it bad! Previous leads had taken him throughout Indonesia and Thailand and on each occasion it was case of ‘you should have been here last week’; this seahorse was more of a Houdini than Bin Laden, it just didn’t want to be found! This time round Snoops had good hard intelligence, the sort of intel that James Bond would give his life for. There had been a recent sighting of the Tiger Tail running the show at Ducomi Pier located off Dumaguete in the central Philippines. A quick smashing of the VISA and Snoops was on his flight, off to finally have it out with his arch nemesis the Tiger Tail. 30 hours later, via a brief layover in Singapore Airport where Snoops was almost signed up as a F1 driver, Snoops was kicking back in the pool at Pura Vida resort, home to Sea Explorers dive centre. The next morning they were off on the hunt, now was the moment of truth for Snoops. He wasn’t getting any younger and these globe-trotting adventures around the globe were starting to take their toll on his body; he wasn’t the spritely young puppy anymore that he used to be! It was only 10 mins into the dive when the seahorse tracker (aka dive guide) started banging away like a bed head in Kings Cross; he’d found the goods! Snoops dashed over to encounter the tracker with a seahorse cruising around in front of him... but it was the wrong seahorse! This was just your run of the mill average Joe Blow ‘common seahorse’...didn’t the seahorse tracker realise that the Tiger Tail has double cheek spines whilst the common seahorse only has one??? Snoops was peeved!!! He’d flown all this way on the promise of a Tiger Tail only to be shown a boring #%#! seahorse that he’d seen a billion times before. This just wasn’t good enough and Snoops turned his back and swam off in disgust! 4 more days of searching and the Tiger Tail was still proving to be elusive, Snoops was at his wits end. All this way, all this money and the Tiger Tail wasn’t to be seen. Snoops did however manage to get rather up close with a curious flamboyant cuttlefish. This was pretty cool until the cuttlefish started to change colour and wrapped her tentacles around his body...even though it was doing a good job at matching his fin colour, Snoops was very reluctant as he wasn’t all that keen on interspecies relationships!!! There was one more dive to go, and Snoops was insistent that they went back to Ducomi Pier for one last look. It didn’t matter that the Tiger Tail hadn’t been seen there for the past 5 days; he was chucking all his bones in the one basket and hoping his Tiger Tail numbers would come up trumps. As Snoopy was approaching one of the pylons he encountered a Giant Snake Eel in the sand. Just as Snoops was checking him out all hell broke loose. Unbeknownst to Snoops, the snake eel was in cahoots with the Tiger Tail and lashed out dragging Snoops into his den. The world went dark for Snoops... was this it – could this be the end for Scuba Snoopy? But in a moment of ‘Bondness’, Snoops pushed his reg down the eels throat and purged... purged like he’d never purged before. With an almighty burp, the Snake eel spat Snoops out and sent him flying into one of the jetty pylons. However a miracle occurred! By divine intervention, Snoops had been thrown into the sacred pylon. There it was, right in front of his little black button nose, the holy grail of the seahorse world. The top dog, the underworld king, the Tiger Tail had been found clinging to a sponge under Ducomi Pier. Now was the moment of truth, was the Tiger Tail willing to cooperate or was Snoops going to have to open a ‘can of kick@rse’ and perform his Jackie Chan moves. But it was over in a flash... the Tiger Tail stuck out his tail with a “How do you do’ and Snoops was in... he’d been accepted into the brotherhood of seahorses. And that was it. Snoops had at long last tracked down his seahorse and could finally hang the sign “Mission Accomplished”. Finally, this little puppy dog could sleep in peace and not worry about whether the Tiger Tail would ever be found, his work here was done. So where to next for this aging Puppy Dog? One heard rumours that the sharks were calling again...the sharks with the big pointy teeth were asking who let the dogs out....
