Critters of the Lembeh Strait | SEA WARS – The Flamboyant Cuttlefish Strikes Back (Part II)

Posted on by

 

In part I of this series, we saw a newly hatched flamboyant cuttlefish (Metasepia pfefferi) getting snatched up by a small mantis shrimp, a surprising choice of meals since they are widely (but perhaps wrongly) believed to be toxic. In this latest episode II, we see a reversal of roles when an adult flamboyant cuttlefish snatches a mantis shrimp to feed on, so it’s not always predictable who is the hunter and who is the prey between these 2 species! The slow-motion part of this underwater video shows in amazing detail how the flamboyant carefully extends its two feeding arms, then at lightning speed grabs its prey and grips the mantis with its suckers, waiting until the mantis tires before consuming her crispy crustacean meal.

How to Photograph ‘Fangblennies’

Posted on by

Fangblennies make interesting subjects as they often can be found in bottles where we can separate them easily from the distracting or unappealing background. They’re often under-appreciated as they’re relatively common in the mucky sites of the Lembeh Strait. Giving them a little bit of time to get used to the camera in front of them, they will pose for the camera very easily. Sometimes they even yawn! There are different opinions on why the yawning happens – either to display the impressively big mouth and scare away possible enemies, or to stretch the jaws, or just because they’re tired.

So here’s how to shoot them: Just get very close to fill the frame with the subject and then wait….at first they might hide in the bottle or hole they hang out in, but after a little while they will come back out. So take some test shots while they’re still in the bottle to get your exposure and background color right, after that is done you just have to wait until they’re in the right spot and then – bang!

Being patient sometimes pays off – after waiting almost 20 minutes and firing at the exact moment of action, I got the lucky shot…Striped poison-fangblenny (Petroscirtes breviceps) – Canon 7D, 60mm macro, ISO 160, f16, 1/200sec, 1x INON Z-240 with DIY fiber-optic snoot

The two enlarged, grooved canine teeth for which fangblennies get their name are situated in the lower jaw. The fangs can get very large and while not especially dangerous to most people, fang blenny bites can be quite painful. Fortunately, because of its small mouth, envenomation of humans by this animal is unlikely. That being said, some of the species we see here in Lembeh have fangs up to 1cm long – I’m sure you heard that before: look, but don’t touch! The two most common species we have here are the striped fangblenny (Meiacanthus grammistes) and the striped poison-fangblenny (Petroscirtes breviceps), which mimics the former – they look very similar at first sight, but upon closer inspection you can tell the difference. Meiacanthus grammistes has a small blueish-black spot near the head.

The striped poison-fangblenny (Petroscirtes breviceps) can also change color at will and sometimes you can get different images within seconds:

Sometimes fangblennies also make a nice black and white image – The striped poison-fang blenny (Petroscirtes breviceps) yawning for the camera (this is a screen-shot from footage shot with the SONY A7RII, 90mm macro lens)

When diving coral sites in Lembeh, we also often see the “smiling” bluestriped fangblenny (Plagiotremus rhinorhynchos) which mimics cleaner wrasses. This species can also change color at will, and can be orange as in the image below or display black and blue stripes to blend in with the cleaner wrasses. I like to shoot them with narrow depth of fields (low f-numbers) and by moving the strobe around, the coral they sometimes sit in can create dramatic shadows even without snoots.

Almost all of these fangblennies are not skittish and fairly large (around 10cm/3inches) so pretty much all macro lenses are suitable for getting good shots.

Critters of the Lembeh Strait | Episode 14 – 2015 | Crustacean Station Part 1

This week’s episode is all about crustaceans. Watch as porcelain crabs use their delicate filter appendages to try to catch food floating in the water, and marvel at the sheer diversity of this family of critters ranging from box crabs (also known as ‘shame-faced crabs’), porcelain crabs and slipper lobsters to outrageously decked-out crabs sporting sponges on their heads! Enjoy this close up and personal glimpse into the world of crustaceans.

Critters of the Lembeh Strait | Episode 13 – 2015 | Eye Spy A Little Eye

Our eagle-eyed guides seem to be magic – where you might only see a bare sandy slope, they find a cornucopia of beautiful underwater animals to show you. In this video you first see these talented guides’ eyes (‘how did he find that?!’, everyone says), and from there we move on to close-up footage of some of the most fascinating critters’ eyes. Mantis shrimp are featured, with the most complex eyes on the planet, along with other striking critter ‘peepers’ such as those of the puffer fish, crocodile flathead and, one of our favorites, the footage of the blue-ringed octopus’ eyes with the chromatophores pulsating and changing color is mesmerizing.
