Before I start, thank you to all the people who have started following my blog recently! I hope you’ve been able to get out and see some herps yourself!

“Mudskippers” aren’t a reptile or an amphibian. They’re a family of fish – though amazingly, one that can breathe air and spend some of its time on land. Mudskippers are one of the neat sights that you can see on the mudflats of Bangkok’s rivers, along with fiddler crabs, several species of water birds, and (at night) several species of water snakes. As a little break from the herps, here are a few mudskippers I photographed on the Chao Phraya River one day.

First, some Goggle-eyed Gobies (Boleophthalmus boddarti).

Then a few Giant Mudskippers (Periophthalmodon schlosseri).

Here are both species of mudskippers with a fiddler crab, the other most common resident of the mudflats:

Other neat things on the river include terns:

One day there was a jellyfish explosion. I’ve never seen jellyfish on this river on any other day, but this day there were thousands of them!

Here are some monitor tracks in the mud. They are almost prehistoric looking.

I haven’t out to Bangkok’s mudflats or mangrove groves at night, so I haven’t personally seen the Dog-faced Water Snakes, Mangrove Pit Vipers, and Brackish Frogs that can live in this intersection between freshwater and the sea. But that would be a great project for anyone who has access to such a spot in the dark. Bangkok’s brackish waters are quite an interesting ecosystem.
