Whilst all these fish have a limited sucking ability – they are able to swallow their food – it is not necessarily correct to assume that they can attach themselves to a submerged object by suction; though their behaviour may give that impression, the orientation of their fins and a flow of water can give sufficient downward force to temporarily attach themselves to an object.
