Into the Wet Tropics 1.0

Most people don’t picture Australia as a place of lush tropical rainforests, but it may surprise some of you that there are some small pockets about the place. One of the biggest is the Wet Tropics World Heritage region of far North Queensland. With Cairns in about the middle, and Cooktown to the North and Townsville to the south, it covers only about 1/1000th of Australia’s land mass. So, the plan was to be joined by co-contributor Phil Lewis who was to be driving up from Brisbane- heading out to Cooktown then exploring southwards back to Brisbane over two weeks.

I arrived earlier by a couple of days so I met up with my mates the Heiner brothers. Andy and Henry are about as far from normal as one can get. Great guys they do things rather… differently. For example, I was met at the airport by them in a small sedan with a massive furry mustache attached to the front. Thrift shops are never driven by when a Heiner is in the car. More on that later…

The first destination was the Cascades near Cairns. This is a section of Freshwater Creek that flows between pools and cascading riffles. Setting up the camera, I jumped in to come face to face with loads of Jungle Perch (Kuhlia rupestris) but the water was milky and they kept just out of range. A Macleay’s water snake (Pseudoferania polylepis) was foraging around the boulders. Only having the macro lens at the time, I snapped a head shot.

The Macleay’s water snake is harmless to humans, eating mostly fish.

Bullrout (Notesthes robusta)

Not far away was a large Bullrout (Notesthes robusta). Bullrouts are also known as Freshwater Stonefish, and, like their marine cousins have sharp venomous spines that can cause intense pain if handled or trodden upon.
Sitting on a rock, it began to swim away. I managed a few photos before it swam in front of a pair of boulders. An enormous eel was residing in there, so big in fact I reckon I could not have fit both my hands around it. I declined to try this experiment. The Daintree was not too far up the road, so we packed up and headed over there.

The Daintree would perhaps be Australia’s most famous rainforest. One of few places on a large landmass where rainforest meets the sea it is home to a bunch of remarkable habitats otherwise found in places like New Guinea and parts of Melanesia. The streams empty right into the sea with little or no estuary in between. This is important for a few species of rather amazing little gobies. The species I wanted to see the most were the Stiphodon cling gobies. Like all freshwater cling gobies, they live in fast flowing coastal streams, scraping algae from the rocks. In the wet season, males become intensely coloured. Pairs spawn in the streams, and newly hatched fry are swept out to sea where they develop before returning to the streams to continue growing to adulthood. In only 1987, Gerald Allen found Australia’s first Stiphodon specimen south of Cairns at Innisfail. For years, no more were found. Recently they were re discovered in many Daintree rivers and a bunch of species were added to the list. Otherwise Stiphodon are far more abundant outside Australia in PNG, Indonesia and Polynesia/Melanesia all the way to Japan.

Walking up one of the creeks, it wasn’t long before I found a heap of Stiphodon atratus – the Black cling goby. Several striped females were grazing from a rock, while males displayed around them. With a black body and purple/blue/green highlights they were amazing to watch. I put on my mask and slipped into the water to photograph them.

Males would claim rocks in the sunlit areas, driving away others. Occasionally they would display to females by hovering with their heads up, showing the electric blue fin and tail margins. Conditions were terrible: low, tannin stained water made photography hard. Silt was easily disturbed and the tannin made everything yellow, throwing the white balance of the camera way out. Significant colour correction was needed to get the white balance to look normal. Also, the tannin robbed the strobes of efficiency, making them fire for much longer, blurring the movement of the fish.

But time was running out. I had to get back and meet Phil in Innisfail as he was soon due to arrive. We met a few hours later and set out for the “Boulders”, a lovely park with clear, fast water flowing through large blocks of granite. It was well and truly dark by then, and the frogs were out in force with the arrival of a small storm. Immediately we heard a heap of Common Mistfrogs (Litoria rheocola) calling earnestly along the creek. But we walked past them and on to the riffles downstream. The first frog I saw was a greenish Waterfall Frog (Litoria nannotis). Only a sub adult, it clung to the granite boulder easily. This species lives almost exclusively in waterfalls, clambering about with extreme ease like a gecko, jumping into the water when threatened.

On a nearby boulder, an Australian Lacelid (Litoria dayi) sat, calling with a short, sharp creaking grunt. When we approached, it crouched down, eventually closing its eyes. The name Lacelid comes from the pattern on the lower eyelid, visible only when it is closed.

Australian Lacelids were thought to belong to the New Guinea genus Nyctimystes but recent evidence places them in the “standard” Australian treefrog group Litoria. Either way they are unique little frogs.

Moving along, we dodged massive eels, disturbed a platypus and found a bunch of common mistfrogs calling on the rocks and leaves over the stream. Here they were greenish, those I have seen an hour or so south were more brown.

It was now time to go, we had a huge morning ahead as we had planned to go to the Daintree again.

The next morning, we awoke at the Heiner house in Innisfail to Andy running around yelling excitedly. Apparently a cassowary was just outside. So I grabbed my camera and we headed out into the rain. Sure enough, a large cassowary was pecking away at the neighbor’s tree. I managed a few photos before it slipped through the trees and into the jungle.

So we set off in Phil’s car. He had just bought it, no more than 11 days before. While he was in the bank in Innisfail I checked the oil. It was white. Phil had mentioned an overheating problem, and this was the answer. A blown head gasket at least. This is not the kind of thing you drive around on, so we called a tow truck and got a lift to a mechanic in Cairns. So for the rest of the trip we had no access to Phil’s car. A real spanner in the works but the journey was far from over…
