The hag moth larva is only about 3/4 of an inch long so not sure what you saw that was the size of the palm of your hand...perhaps you could take a photo for Id.
Starfish bug thing by: Mandy
I went into my basement to do laundry. When I walked over to my dryer I saw what looked like a flat starfish. I freaked and ran (deathly afrais of spiders). Later I went back down and it was on the side of the dryer and spread out about the size of my palm. Wish I new what it was, Oh yeahand I live in South jersey. never saw it before.

Monkey slug larva it is! by: Moni

Donalda has described your critter completely. These larva feed on many woody shrubs and trees throughout the whole eastern half of the US.
Some researchers do not feel this caterpillar can sting. If you are sensitive it is always wise to be careful.
Hag moth Larva by: Donalda
I believe your caterpillar is the Monkey Slug (Hag Moth Larva) - Phobetron pithecium, of the family Limacodidae. It is about the size of a large thumb nail. The curly "arms" are actually just lobes of hairy flesh atop the caterpillar. If you turn the caterpillar over you'll see the usual legs and head,as shown in your picture. It very often is mistaken for a leaf gall.
Those hairs on the "arms" are capable of stinging, so this caterpillar is very well defended.
