I got the best of both worlds!

  • If im not feeling this whole air and lungs thing, I simple just get into the water and use my gills . Pretty cool huh ?

  • if I somehow get upside down , I simple flip my telson, or tail and flip back over, or I can use it to steer while im in the water .

I get around by...

  • Using my 8 pedipalps as walking legs .

  • Using my 2 "pusher legs" while taking a swim .

Bon Appetit !

  • Mollusks

  • Annelid Worms

  • Bits of fish

Sadly I don't have jaws, so I have to grind them using my gristles on my legs and a gizzard that contains sand & gravel .

Greatest Enemies..?

  • Sea Turtles

  • Sea Gulls
