Of the top ten posts of all time, number five is my personal favorite. As you might imagine, it deals with catfish—those bewhiskered masters of freshwater survival. Catfish live on all continents (other than Antarctica—where they once lived) and they thrive in virtually every freshwater habitat worldwide. The siluriformes have even left freshwater and begun to reconquer the ancient oceans from whence all chordates originally sprang. They are a phenomenally successful family—one of life’s greatest success stories. When Earth life finally leaves home and blasts off into the greater firmament, I am sure catfish will find a way to tag along in our fresh water supply (assuming we can ever look up from our stupid I-phones and celebrity folderol for ten minutes to make such a thing happen).
Ferrebeekeeper has featured all sorts of catfish posts: catfish in art, the politics of farm-raised catfish, colorful catfish, venomous coral reef catfish, even terrifying underworld gods that are catfish! There are upside-down catfish, and catfish which care, and even wild catfish living in Brooklyn (both at the beach and at the reservoir). Tune in later this autumn when we will go all celebrity chef and cook a delicious catfish! I guess what I am saying is that I really like catfish! I admire their astonishing versatility. The secret to their success is straightforward but hardly simple—they have a vast array of astonishing sense organs which allow them to thrive in environments where other fish are lost. Even if their habitat is dark, turbid, or chaotic—the numerous senses of the catfish (some of which are not possessed by humans) allow it to evade predators, find food, and carry on a social life which is often surprisingly elaborate. You can read all about these astonishing senses in Ferrebeekeeper’s fifth top post of all time “Sensitive Siluriformes: How Catfish Perceive the World.”
After you are done reading (or re-reading) the original post, I hope you will pause to reflect on how astonishingly beautiful and sophisticated life is. Most people I talk to initially dismiss catfish as lowly bottom-feeders (or possibly talk about them as delicious sandwiches), but they are magnificent organisms which live everywhere based on senses we are just beginning to understand. They are also related to us: distant cousins who stayed closer to the traditional ways of our great, great, ever-so-great grandparents the ancient lobe-finned fishes of the Silurian. But despite their adherence to a traditional aquatic lifestyle the catfish are hardly unsophisticated cousins!
