Fertilization in a Sea Urchin Egg

[@tortul1462]

Hello. May I ask. It was not stated in the video. The influx of Sodium ion and also the water that causes the vitelline envelope to rise are primarily environmental right? Because these are all happening in the ocean. So technically this fertilization evolved to occur in salt waters. Right? Pls confirm ( - 3-)❤
