Cominella Glandiformis is most widely distributed among the many Cominella spp. This Mud whelk straightforward enough, but there are a surprising number of decisions required of the bird if it is to be successful.

This allows them to draw in their water current with precision and accurately locate the smells of decaying food. Large snails break quicker with fewer drops. Scotland[ edit ] In Scotlandthe word "whelk" is also used to mean the periwinkle Littorina littoreafamily Littorinidae.

They live exclusively Mud whelk Mud whelk sheltered beaches, principally on shores of mud. However, the prospect of a "biological clock" controlling daily rhythms has been investigated recently Kennedy,but with inconclusive and indecisive results.

You also need to watch out for cone snails. Higher temperatures should mean that the whelks react more rapidly and reach the food source sooner because the smell of the cockle is sensed faster by its osphradium in high temperatures.

These mud whelks have a keen sense of smell and can respond to food up to fifteen metres away Chemotaxic response triggered by the chemosensory organ, osphradium. Studies on Mandarte Island, British Columbia show that the crows prefer the largest specimens to drop, based on what appears to be an initial estimation by eye and, then, an estimation by mass see histogram upper Right, dark bars signifying sizes selected for dropping.

Temperature fluctuations in this habitat are habitual to the whelks. Usage[ edit ] The common name "whelk" is also spelled welk or even wilk. Asia[ edit ] Skewered whelks from Japan.

Take care when gathering mud whelks, as they can easily be mistaken for icecream cones. These adaptations are substantial as my investigation is based on the feeding response time in different temperatures. Despite this, northwestern crows Corvus caurinus find them quite easy to break by flying up and dropping them onto rocks.

Intensity of individuals is greatest where the beds of Austrovenus Stutchburyi and pipi are densest as these are its primary food source. The main difference is the opening which on a cone snail is a slit that runs across most of the length of the shell. There is not much evidence as to its activity period.

Wherever Cominella Adspersa and Cominella Glandiformis are found in the same area, Cominella Glandiformis is abundant in the upper regions and adspersa in the lower regions.Physical: Mud Dog Whelks are primarily dark brown to black, with white patches or stripes.
