Glass catfish

The first trait we notice about Kryptopterus bicirrhis is of course its transparency hence the common name of 'glass' or 'ghost' catfish. The body is virtually transparent with scattered patches of pigment on the head and underbelly. We can see the swim bladder inside the body cavity adjacent to the pectoral fins and other internal structures, such as the vertabral column, can be seen.
In its native waters of southeast Asia you would think that such a soft bodied fish would stand out and prove an easy meal for predators, but to the contrary the glass cat can prove itself to do a disappearing act in the more murky river waters of its habitat
