Biotopes of Hong Kong | Hill Stream Habitats | Blue Neon Stiphodon

Jeffery Chan Biotope, Biotopes of Hong Kong, Conservation Leave a Comment

Hill stream habitats in Hong Kong are home to some of the most endearing and enigmatic fishes on Earth. These oxygen-rich, cool mountain streams or often, torrential rivers, provide crucial habitat, not only for exclusively freshwater dwelling species, but also form important migratory routes and nurseries for anadromous, amphidromous and catadromous fishes, those which migrate upriver, those with complex breeding strategies involving both fresh and saline systems and those which migrate downriver to the sea to spawn, respectively. One Hong Kong hill stream species which is particularly fascinating is the goby Stiphodon atropurpureus. From their striking iridescence, their adaptation of …

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 Japan | Stiphodon percnopterygionus

Marcelo Fernandez Biotope, Biotopes of Japan 1 Comment

The first time I saw a photo of a Stiphodon sp. I felt a sensation of observing a masterpiece of art, I have always been amazed (and still feel the same today), those colours of the males combined with the characteristic iridescent lines near the mouth make them special and unique. This “drawing” made them practically perfect. Then researching and looking for information, over time, I understood a little more about their biology, I now knew their real size, how they always tried to be on top of the rocks to control everything visually from there. Of course, the characteristics …

Years ago, when I went to this beautiful province for the first time, I asked myself which fish would inhabit the Iguazu Falls, although I like all the fish, my thoughts were oriented (as always) towards the aquarium fish.

Marcelo Fernandez Biotope 2 Comments

A Killifish that can only be found in one single lagoon  Who would believe that there are fishes around the world that exist only in one very small lagoon and nowhere else?
