❥ Human beings are monstrous, the shark is just large
❥ The poet is humbled and unsure of his own superiority (contrasts him insulting the shark at the start)
❥ Poet questions himself (is he a monster, an intelligent being who has failed to use that intelligence usefully?)
❥ As well as seeing the shark in a new light, he has also seen himself in a new light
