Emerald Tentacle Snail

Size 3mm extended crawling length. Beautiful little snail. It has a flat shell that is partly covered and may not serve to retract totally. It has two dark, parallel stripes on its head that lead to the beautiful, almost glittery emerald tentacles. The tentacles seem too large for its body. It could be a juvenile. The animal was found crawling on my boots in dense rainforest habitat.
