The spotted whelk co exists with many other organisms on the kaiua stream such as: gracilaria secundata, maomona lilliana, chione structchburyl, and cominella Glandiformis. This could be because of behavioural adaption such as living in big clumps together so that a predator be put off by their size together and increase their chances of survival of abiotic factors such as sun exposure, salinity concentration or the tide coming in and out. The upper end of the stream has shallow water and is very dry. Here it is seen cleaning necklace weed during an early morning low tide. Presence of other organisms: other organisms that live along side spotted whelk are: chitons, oysters, oyster borers, neptunes necklace, algae, plankton, small fish and other spotted whelks. P. Structural: they have a “flap” that is covered in mucus that closes when it is high tide to make sure that no excess water gets inside it or to close it when it is exposed to the sun to stop it from drying out or when the salinity concentration is high. My kite graph tells me that at the 0m there are 0 mud flat snails on the high tide of the stream. To prevent being washed away it has a strong attachment to rocks, these are structural. Like all organisms in the mollusc family, the mud flat snail has a large foot covered in mucus to help it grip onto rocks and cement itself into place when waves crash against the rocks.

The mudflat snail is a omnivore and is also a scavenger and uses it siphons to detect food from over 10m away. Structural: It also has a “flap” covered in thick mucus to make sure that it does not dry out when the tide is low and the salt concetration of the water is high, or make sure excess water does get int its shell. It has high resistance to rust, corrosion and tarnishing, which requires minimal maintenance. My kite graph shows this as the shape of the kite that the mudsnail makes is a long skinny kite. Lives in groups to prevent moisture loss and in turn dessication by covering the lower layers of leafs. Where are they found: they are only found in New Zealand.
