The Lurker *new mod idea

My imagining of this mob would be a deep stone colored alligator-like-creature that would blend in to skulk and the deep dark biome. This mob would be visible but hard to notice if the player is carelessly traversing the deep dark. The lurker would make a small jump forward from its hiding place when the player gets close. I imagine this mob would scare the player enough to make them act sporadic which could set off some skulk shriekers. I imagine this mob wouldn’t be very strong health wise but could deal a heavy blow with their powerful bite.
