Species Profile
Scaphander punctostriatus, common name the giant canoe bubble, is a species of sea snail, a marine opisthobranch gastropod mollusk in the family Scaphandridae, the canoe bubbles.
The Giant Canoe-Bubble faces significant population declines primarily due to habitat degradation from coastal development, pollution, and climate change impacts on marine ecosystems. Bottom trawling and dredging activities destroy the soft sediment habitats essential for this species' survival and reproduction.
