Fangs, Babies & Butterflies

Just think - this beautiful baby sponge seen off Gaya island on 30th August 2008, may already be well on the way to being a giant barrel sponge capable of hiding Porcupinefishes or Lionfishes...

Anyway, I'm still catching up on my fish observations - this time data from 20th February this year. First a confusion to clear up: Until now, I have persisted in calling a certain type of Wrasse Oxycheilinus orientalis because a significant authority suggests it. However, having read further, I am pretty certain that what I have seen is actually called O. rhodochrous even if the first authority doesn't recognise it. And whilst reviewing my photos of the suspects, I realised that one was just wrong. Further investigation convinced me that in the past I have actually seen a second species (not yet listed for TARP by myself nor by Gerry Allen previously) called Oxycheilinus bimaculatus.

Alongside this are three more fishes not previously listed in TARP by either of us: Moray Gymnothorax zonipectis (normally only visible at night so very nice to spot on a daytime dive), Wrasse Pseudocheilinus hexataenia (which hides most of the time and only appeared to me in the background of a photo of another fish), and yet another large Grouper species (hooray!) Plectropomus leopardus.

Lastly, there were two special fishes which Gerry had already seen but I hadn't: Butterflyfish Chaetodon auriga (I sometimes wonder why the Butterflyfish presence seems to have dwindled since 1992), and the very localised (known only from the coast of Sabah and Palawan island) Fangblenny Meiacanthus geminatus; with its poison fangs, it has prompted some very good mimics - at least one of which (the juvenile of Scolopsis margaritifera) can also be seen in TARP.

In total then, my TARP list stands at 414 fish species, and the combined list total at 548 (it will take me a while yet to update this list on line).

Squeezing Sponges

I can't resist commenting now that we have official opinions about the upcoming impact of the global financial crisis on Sabah's tourism. Yesterday a drop was predicted which seems much more realistic to me. I feel sorry for those who depend on tourism income. Yet I also feel a little bit happier for the denizens of TARP who might just get a little less squeezed by all the attention they have been trying to get used to in recent years.

I've been investing huge amounts of effort reformatting my fish guide mock-up. Undoubtedly no one will now be wanting to invest commercial money in the project in the near future; after all, who would buy it? But as a not-for-profit conservation project a donor might be interested to cover the costs. And if I'm willing to make no profit and still can't get it published then maybe I will post the book in PDF format on-line so people can print their own copies: perhaps on waterproof paper or for laminating if they want to take it under water.

I'm also looking into obtaining photos of previously unseen fish (by me) via other outlets so as to improve the comprehensiveness of the guide. We'll see: they too are likely to be feeling the pinch and may not have much time now to help.

Here's a gorgeous Poripheran (sponge - possibly Family LEUCETTIDAE) which I hope will have a less pressured 2009 (photo taken on 21st July 2006 off Sulug island).

Sponge-heart

It could be blood vessels on the surface of the heart. In fact, it is a form of Sponge from the Family CRAMBEIDAE (possibly Genus Monanchora) taken on 6th July 2008 off Mamutik island.

Further to my second snorkelling session last week (28th July), I can now report back on two new species of fish uploaded to my Album and Checklist (totalling 366 species now), namely: The Moral eel I mentioned in an earlier blog (Echidna nebulosa), and an apparent predation escapee in the form of a small roughed up Rainbow runner - Elagatis bipinnulata.

I've also uploaded the panel for the Trevally - Caranx melampygus - from 26th July with the better photos from the 28th. Additionally, I've added panels for the Adult of Damselfish Neoglyphidodon oxyodon (modifying the Juvenile panel along the way) and the Initial Phase form of Parrotfish Scarus psittacus. Lastly, I've modified the panel for Lutjanus carponotatus having photographed a Juvenile (not sufficiently different to merit its own panel but confusingly different if seen small to merit inclusion alongside a parent).

Shock & Awe

My youngest son and I were glued to the television last Sunday, watching the first of the BBC's new three part series called 'Pacific Abyss'. Stunning and inspiring to say the least! Diving to the so-called 'Twilight zone' between 60 and 150 metres, it was astonishing to me that so much reef life - and several new fish species - could aggregate so far down. Talk about jealous! And for my 11 year old, hugely keen as he is on natural history, came fighting talk about becoming a marine biologist... Hopefully we'll find a way to watch the second in the series next Sunday.

My picture today is more mundane, but striking none-the-less: it is a series of pipes laid down by a Sponge which I think can be located in the family THEONELLIDAE, found back on 23rd June 2007 near the Hanging Garden off Gaya island.

Incidentally, I have withdrawn my experimental TARP fish identification key website for the time being - after reviewing it, I don't think it is fit for purpose and I will ponder its replacement further. The checklist and album remain in place.

Enjoyable Sabah Society presentation

I hope the attendees enjoyed last night's slide show at the Sabah Society on the delights of TARP's underwater environs as much as I did presenting it. The picture above seemed to catch the imagination of a number of people there: initally set up as a 'boring' shot of the overlapping edges of disc anemonies (family DISCOSOMATIDAE) it transpired later that the flash had reflected back off an apparently drab yet deeply orange (depth tends to reduce red tones to grey) sponge beneath them giving the sense of a lava back light. It was taken on 27th October 2007 on the southeast slope of Gaya island.
