There are all sorts of interesting, weird and wonderful creatures in the ocean Here a few examples:
l The tentacles of the giant Arctic jellyfish can grow up to 36m in length.
l The four-eyed fish swims at the surface of the water, with each of its two eyes half in and half out of the water. The fish looks for insect prey on the surface, while watching for danger below.
l When danger threatens the porcupine fish takes big gulps of water and swells up to four times its usual size.
The stiff spines stick out to make the fish look like a spiky football. - sstg.org; frontiernet.net; pembrokeshiremarinecode.org.uk
