Leviathan meaning and symbolism

What’s the metaphorical meaning of leviathan whats the deeper meanings of it? In general, what is this? Thank you

A leviathan is a huge whale, for as the largest of mammals, symbolizes or typifies a particularly large creation (Tehilim 104, 25-26), which compared to its Creator is laughably small, even like a toy (see Job 40, 29).
