I’m Aiman Azmi, a student born and raised in Peninsular Malaysia. I have been observing and collecting fish around me since I was a kid, I’d eagerly follow my father, a biology professor, on any fish collecting trips he would go on and have been fascinated by freshwater ecosystems ever since. The habitat I chose to write about is a freshwater swamp in Tanah Merah. Situated close to the border with Thailand, Tanah Merah is a district within the state of Kelantan, Malaysia. The words “Tanah Merah” translate to mean “Red Earth”, and even as far back as the 7th …

Zaheer Afie Biotope, Biotopes of Borneo, Uncategorised Leave a Comment

Due to work and college commitments , I had almost no free time to do anything other than rest. With the COVID-19 situation happening globally, Brunei was also affected, borders were closed and we couldn’t travel internationally, thus I decided back to go to the jungle to release some stress. The border closures resulted in the Bruneian government opening up the Temburong bridge (now formally named as Sultan Haji Omar Ali Saifuddien Bridge). Temburong Bridge links the 3 mainland districts of Brunei with the Temburong exclave and is the longest bridge in Southeast Asia, 30-kilometre (19-mile) long. As there is …

Biotopes of Zambia | Neolebias lozii, a critically endangered fish from the Barotse floodplains

Chris Englezou Biotope, Biotopes of Africa, Uncategorised Leave a Comment

Neolebias lozii, also known as the Banded Neolebias is a species of critically endangered Characin in the Distichodontidae family. The two sites where the species has been found are less than 2 km apart and the streams meet <5 km downstream, and the area of occurrence consists of only a few km of streams 1 to 2 m wide in the dry season. In terms of the alien invasive threat, the streams are classified as a single location, but would be classed as two separate locations in the event of an agricultural chemical pollution event or road tanker spill. The …

Biotopes of Brasil | Rio Xingu, home of the Zebra Pleco

C.E. Fish Essentials Biotope, Biotopes of South America, Uncategorised Leave a Comment

The Zebra pleco Hypancistrus zebra is endemic to the middle of Brazil’s Rio Xingu (pronounced shin goo) and is among the list of catfish species at risk from the Belo Monte dam. It lives at a depth where the surroundings are, at best, pretty gloomy, if not completely dark. It lives in the cracks, gaps and natural caves found in the very specific type of rock found in the river. This is dark brown to black hard igneous rock that, in shallower water, is set in tan-coloured sand. There is very little submerged wood, there are virtually no plants and …

C.E. Fish Essentials Biotope, Biotopes of Africa, Uncategorised Leave a Comment

Ecology The Ropefish, also known as the Reedfish is the only species in the genus Erpetoichthys, and is an incredibly hardy, nocturnal species. Due to its poor vision, the Ropefish relies on its excellent sense of smell to locate food. It’s closely related to the Polypterus genus and both these are some of the last surviving relatives of very ancient species. Fossils of earlier relatives have been found that date back to the Triassic Period, which occurred during the early development of the dinosaurs, more than 200 million years ago. This species is a freshwater species also found in brackish …

Located deep inside the Labi jungle in Belait District, our latest adventure takes us to visit three different waterfalls, each located in the upper stretches of the Mendaram River; our final research point was at the third waterfall, the location of which can be seen on the map below. On 24th March 2018 we commenced our journey at around 08:30, the sun was already shining but I assume that it rained the night before as parts of the road were wet and gradually drying. Before we hiked uphill, approximately 100 metres from the parking spot, we managed to come across …
