What are these things?

Came across these yellow snails on Cabilao Island, Philippines last weekend. They're about fingertip size and seem to be hanging by threads. Not sure sure what was going on in this series... mating? Also, came across a nudibranch. Not sure if it was caught by these snails or vice versa?

Wentle traps usually lay their eggs in masses on the Tubastrea. The orange blob on the line in picture 2 looks like eggs to me. But not sure what the tarsan impression is for.

thanks Alex... interesting... Wondering what the nudi was doing? Making a meal of the eggs?
