The butterfish is well suited to life on the rocky shore – it can survive out of water between the tides by hiding under rocks and seaweeds. As its name suggests, it’s a slimy fish and very difficult to pick up! In the winter, the female butterfish lays a ball of eggs and both parents take turns guarding them. Tiny larval fish hatch out and join the plankton.
