Default Blue Dragon

Hieee all

Blue dragon Pteraeolidia ianthina perched/sleeping on a funnel weed Padina gymnospora




Normally this species of nudibranch exhibits colouration that is closer to the purple hue, whereas this one was displaying colouration that is nearer to cyan and had a blue-ish tint to it.

cheers and enjoy.

c'mon guys where art thou's pictures??

The Blue Dragon has evolved ways of harnessing solar energy. While feeding on solitary hydriod Ralpharia it swallows microscopic plants called zooxanthellae, Within the nudibranch the plants use the sun's enerygy to produce sugras, passing on a considerable portion to the nudibranch for it's own use. Adults are blue to brownish purple. Juveniles are white. This species often gather in clusters for 2-3 weeks around egg masses on large submerged rocks encrusted with coraline algae. this nudibranch can inflict a sting, using the hydriod's untriggered stinging cells in its body.

I actually don't always take pictures in supermacro mode, actually my settings are mostly macro.

I just remebered when i was starting out this woman told me this "golden" rule,

Get Low, Get Close and Shoot Up


that has been my golden rule so far. Bouyancy will be a major factor in getting good shots IMHO

one thing i find useful is to know what you are shooting; and to capture the "finer" part to photograph instead of just a downwards ID shot.

Waisj, if you don't mind, perhaps you can share why you don't think these are your "better shots" and how you think the shots can be improved - i.e. "self critic". This will help the rest of us learn on how to improve our own shots!

hi there KTHAN, you are actually quite very close Flabellinas actually belong to the Flabellinidae family, whereas this species belongs to the Glaucidae family. cheers

WOW.. KNG you are really twisting my arm on this....

none ther less, will try my best to throw my 2 cents in this topic we are in.

First of, i guess there are normally 2 types of nudibranch shots that underwater photgraphers are looking for. (besides the normal ID shots)

1. A nudibranch in motion
2. A nudibranch that is still , but stands out within it's surroundings. (colouration, poses) and stuff

why i considered my shots failures,

First off, although the nudibranchs are in motion, i was not able to "convey" the motion through my photographs. -> major failure

The first of the 3 shots that i posted ,are a classic example of trying to squeeze too many things into a frame, i was actually trying to "Squeeze" the Aeolid and a cone shell into the frame, miserablly failed by not being able to adequately controll the DOF. Portraying a shot that is neither here nor there

The second shot, no motion there either. compostion could have been better, couldn't even "show" that the nudibranch was moving. Neither could i "isolate" the nudibranch from its surroundings. thus effectively creating a very flat picture, nothings stands out and nothing captures the EYE, you almost couldn't even ID the Species, miss the most important "feature" of the aeolids, the rhinophores and it's appendages and the gills.

The third shot, could almost feel the motion there, but the rhonophores are not shown, neither does it stand out from its surroundings,
which is just a bad case of background usage. A tip, if i had actually waited for a while more and actually shot from the left side when the aeolid just reaches the edge of the coral head, the shot could have been better, thus creating creating contrast and motion

Please feel free to add what ever 2 cents that i have included, so everyone would benefit from this
