Male Heteroclinus kuiteri can reach a maximum length of 6 centimetres (2.4 in) SL. The colouration of the blennies varies, with both male and female bodies being primarily brown. The blennies are sometimes uniformly brown in colour, but can also possess a white-brown mottled band from the eyes to the tail, or approximately 8 dark brown bands along the body (most frequently shown in females), which become darker on the back. https://en.wikipedia.org/wiki/Heteroclinus_kuiteri Photo R.
