Can someone post a summary of the poem "Seal" written by William Jay Smith?

The poem 'Seal' by William Jay Smith starts with a description of the seal's actions and asks the reader to watch it with him. Action words or verbs used include 'dive,dart swim.' The poet describes some of the scenery the seal passes (watery room, seaweed.) The poet gives a vivid and action-filled description of the skilful way in which the seal moves in water (with a  swerve,flicker,twist,flick.) He describes how the seal can dive to the bottom and flash back up again in terms of measuring the time it takes the reader to eat or think or speak. The whole poem is full of the speed of the seal and ends up at the reader's feet,like the seal, who turns up there with a mouthful of the fish he has caught on his travels!
