Stenohaline animals rely on behavioural adaptations such as moving out of the area, burrowing in the sand and closing their shells or physiological adaptations such as excreting excess salts. Zebra Snails live on intertidal rocky shores. The shell of Conus magus is a very important aspect in its life. There has been little published on this species.

Birds, such as the thrush (Turdus philomelos ), use stones as anvils to break open the snails, and it is possible to count the proportions of different snail types taken by the birds in the shell debris around an anvil; these proportions can then be compared with those in the local habitat. They actively scrape the algal growths off rocks, and this tends to cause erosion over time. Horse Conchs capture and smother their prey with their bright orange-red foot. However, the handsome homes of snails (gastropods) are built only at great cost. The encounter of those gametes produce yolky fertilised eggs, which will further develop into lecitotrophic (yolk feeding) larvae. Gills Snails adapt to an aqueous habitat through the use of gills that take in oxygen given off by underwater plants, while filtering nutrients into their systems through breathing water.

The cats eye sea snail (Turbo Smaragdus) Its a filter feeder that feeds on Microlagae, detritus, and small algae. This helps snails stay damp throughout the day and assists in movement, reproduction and breathing. In both situations, by secreting extra mucus and sealing themselves into their shells, snails protect themselves with trapped humidity and filtered oxygen. When the snail is threatened by a predator or is exposed above the tide, it withdraws into its shell and the operculum seals the opening.
