Hold on tight!


The first discovery on a recent rockpooling trip to Mousehole was this beautiful little fish, a Cornish Sucker or Cornish Clingfish (Lepadogaster lepadogaster). It possesses one of my favourite adaptations to seashore life, with its pelvic fins having evolved into a highly effective sucker, with which it attaches itself to rocks. This not only prevents it from being thrown about by wave action but also presumably acts as an effective protection against predators, as when pressed flat against the rock and attached with limpet-like suction, it is virtually impossible to shift.
