Striped eel catfish (Plotosus lineatus) school

   The head and body range from dark brown to grayish-brown. The body has no scales or bony plates. Two pale stripes run along the sides of the body, extending onto the head. In larger specimens, the stripes are less pronounced. Four pairs of barbels surround the mouth. The serrated, spiny rays of the first dorsal and pectoral fins are connected to venom glands, and a sting from them can cause a very painful wound.
