I found this claim unbelievable, but it is mostly true. It isn't quite the whole egg, it is just the yolk. But that's still a very large cell!

It's analogous to the mammalian egg, but a lot bigger. (And IIRC the egg is the largest cell in humans.)

i guess if it's fertilized then it will soon have more cells
