Shane's World

Greetings and welcome to Shane's World. The goal of this resource is to provide a place where the aquarist and scientist alike can learn and exchange information on Siluriformes (catfishes). When Planet's owner Jools and I discussed this at length (in the mid 1990's), Shane's World was born! Here we have articles from me and a great number of other folks from right across the catfish world. They are roughly grouped into general catfish articles ('Catfishology'), those relating to Geography, Reproduction and Species categories as you see below. Dive in!

Latest Catfishology Articles, alternatively, show all 45 or popular articles.

General articles from authors who just want to write about catfish in the aquarium and the wild. The 'Catfish Basics' series is especially useful for the aquarist new to the catfish hobby. Most recently added articles:

Visually comparing Synodontis petricola & S. lucipinnis by Birger Kamprath (uploaded September 19, 2009)
An in-depth look at telling this two species apart using only techniques applicable to live fish.

The Siluriformes are a large and diverse group of fishes consisting of well over 30 families and 2,500 species. They can be found on every continent with the exception of Antarctica. Their habitats range from the frozen rivers of Siberia to the steamy swamps of Borneo. Species have been found in the Himalayas and Andes at altitudes of over 14,000 feet, while others live in the oceans among the coral reefs. Catfishes range in size from some of the smallest known fishes to the largest. Scoloplax dicra is fully-grown at 1/2 inch while the European wels (Silurus glanis) grows to 16 feet and can weigh 650lbs. These amazing fishes reproduce in about every way we know fishes reproduce. Among the Siluriformes we find mouthbrooders, livebearers (of a sort), bubblenest builders, egg scatterers, cuckoo spawners, nest builders, fish that carry their eggs attached to their mouth, and even catfishes that feed their fry with a body slime.

With so many species coming from such diverse locations and habitats, it is no wonder that finding good solid information about a certain catfish can be tricky. The articles beyond this page come from myself and others with an interest in these fascinating fishes. Among the authors are well known aquarists and scientists, but I want to stress that it is not necessary to be an expert or have a Ph.D. to contribute to the world's collective knowledge on catfishes. If you believe you have something to contribute to this section of this site please drop me a line.
