Distribution and habitat

Echinolittorina hawaiiensis is endemic to Hawaii. ^[2] It is abundant in clusters on rocky shores just above the waterline.

Anatomy and morphology

The shell of Echinolittorina hawaiiensis can be up to 1cm in size, and is round and cone shaped. ^{[2] [3]} The shell of Echinolittorina hawaiiensis has a sometimes sculptured shell due to environmental polymorphism. sculpture. ^[4] The shell also traps water, which allows the snail to hibernate for long periods. They develop into planktonic trochophore larvae. ^[2]
