[Cloverfield] What is Clover's evolutionary background?

Very little about Clover was revealed in both the marketing campaigns for Cloverfield and the film itself. All we really know about him is that he is a newborn and he comes from the sea. 

So, hypothetically, what would Clover's evolutionary history be? Where is his place in the animal kingdom?  Is he a reptile? Arthropod? Amphibian? Mammal? Fish? What time period is his genus from?
All we really have to go on is his design and where he lives, so this should be interesting.

Fairly confident that the creature is simply ripped into existence during the events of the Cloverfield paradox when the particle beam tore a hole in the fabric of spacetime the creature is pulled through from another dimension or just fabricated from nothingness.

This is allued to due to the creature appearing in New York at the exact moment that the particle beam incident occurs.
