Apple Snail eggs

Thank you Machi for the ID suggestion and link.

I'm thinking apple snail because the eggs seem large. http://en.wikipedia.org/wiki/Pomacea_hau...
I don't know exact species, but that might be somewhere to look.

Thank you Scott.

Moved to "others" category.

Thank you KatKiloueka, you are right, I use to have an aquarium with fishes and a couple of snails, and the snails would deposit the eggs in a yelow sac of the same shape of the spotting

Thank you Cindy and Gerardo

Frogs lay their eggs in the water, so it's probably some sort of insect eggs

Very cool spotting!

Nice spotting, Luis!
