Fascinating fish, intriguing coral and hidden venom

Next day was the end of another leg. We hauled in at Lautoka, Fiji’s second largest city. The morning was spent getting one set of passengers off the ship. In the afternoon, a different set of passengers was embarked. Meanwhile, those of us that were continuing the voyage, the in transit passengers, were sent off on a trip to get us out of the way. It was not a great trip. We have done some coach trips that set the bar low and this one was right down there. We were driven to a marina. Given some fruit. Shown how to open a coconut. Driven to a shop and finally brought back to the ship. This was stretched over nearly four hours. The shop, a multi-floor upmarket emporium, was aimed exclusively at tourists to the extent that prices were all in US dollars.

Now the ship was full of strangers again. We spent much of the afternoon doing safety drills, listening to safety briefings and generally being bombarded with information that we had already received twice before. Outside, big black stormy clouds were brewing. Rainy squalls were all around us.

Next morning we were intending a landing at another small Fijian village called Nabukeru. This time the weather was against us. For the most part, we have been remarkably lucky with the weather on this trip. Today it did not work out for Nabukeru. The swell and wind were just a bit too much. We repositioned to an alternative landing site on the north coast but this was deemed to be just as bad. A group of locals, meanwhile, had come out in their small boat to see what we were messing around at. They were bouncing around in their small white boat without any care for the sea state or wind. They shouted “Bula” to us in loud, cheerful voices. This is the Fijian greeting. Often delivered as an explosive shout with wide open arms. All to no avail though. We waved them goodbye and headed all the way back to our landing site of two days previously close to the village of Yasawairara. Here there was better shelter from the land and we could finally put the zodiacs out.

The rest of the day was just about hanging around the beach and the village. For Diane and I, it meant two more snorkelling trips. While many others were lying on the beach or buying souvenirs in the village, we were in the water.

The visibility had improved a little. This helped with the photography. I had found a setting to do with focusing. This helped as well. Unfortunately, I also managed to put the camera in a low-resolution jpeg mode. This did not help. Once you are in the water, it is a bit late to start messing with settings. It is difficult to see well enough for this, so I just tend to assume (hope) everything is set correctly and off we go. Since then I have been studying the manual some more. Partly to help get the right setup but also to find a way to lock everything so that I cannot inadvertently mess it all up when I jump I the water.

My ability to identify fish is still woefully inadequate. Like with bird identification, Google helps a lot. There are also some fish experts on the ship. One thing I have learned, is to not touch things underwater. There are many reasons for this. Much of the coral is quite fragile and also has sharp edges. Possibly worse than this however, are the wide variety of poisonous creatures. The Lined Surgeon fish looks very nice. Bright colours. Easy to spot. Very photogenic. But possesses sharp, venomous spines, or “scalpels,” located on both sides of its tail base for defence against predators.

There was a wide variety of fish on the reef. And a wide variety of corals. I know even less about corals than fish. Corals, somewhat surprisingly, are animals. Although they look like plants or rocks and are sessile (fixed in one spot), they are, in fact, animals. Individual corals have a stomach, mouth and tentacles used for capturing food and defending themselves. They also have a symbiotic relationship with algae. The algae live in the tissue of the polyps and provide oxygen and food (glucose, glycerol, amino acids) through photosynthesis. This process also gives the coral its vivid colours. Over thousands of years, the calcium carbonate skeletons of the coral polyps build up to form reefs. Some of which are enormous.

I saw several schools of yellowfin goatfish. During the day, they often form large, inactive schools for protection. This is great. They stay still so that you can photograph them.

Chevron butterflyfish are very pretty. They feed almost exclusively on the polyps and mucus of the corals.

Surgeonfish are generally herbivores that consume turf algae. They are often found grazing on coral and rocks.

Doublebar Goatfish have a big spot around their eye – making them look like they have big eyes.

A school of Indian Mackerel swept in. These are strange looking fish. They are a reasonable size (20 – 30 cm) and were swimming in a school of 30 or more. They were moving fast and my first impression was that they had plastic bags on their heads. On closer inspection, they were swimming with their mouths open.  These fish are ram feeders. They swim with their mouths wide open to strain plankton and macroplankton from the water using their gill rakers.

Lying on a patterned section of coral was a lizardfish. These are ambush predatory feeders.  Normally they camouflage themselves against the sea floor. This one apparently did not realise that on the regularly patterned coral, it stood out like a sore thumb.

Finally, there was a sabre squirrelfish. These are nocturnal and this particular one was hiding in a hole. I waited patiently for it to come out. Good job I did not reach in for it. They have small spines that secrete venom for protection. While not deadly to humans, their stings can be painful. Do not touch things underwater.
