(pomacea diffusa). the first was aimed at determining growth performance and adaptability with a natural vegetable source (dehydrated lettuce, d ) compared with a composite diet of high content of fishmeal (d = ). snails of three different shell lengths (s ± , s = ± , and s = ± mm) were fed at two different...

locomotion other (foot and mantle) overview d anatomy digestion senses nerves respiration circulation reproduction other shell mantle cavity: the mantle cavity is formed by a fold of the backside of the bodywall (roof) and the head neck and body of the snail (floor). it can be considered as a sac, loosely

attached to the inside of the shell and enveloping the head-neck and the gills-lung area of the body. the top of the mantle cavity (the part away from the shell opening or the posterior part) is separated in two chambers, the left one forms the lung and right one contains the gill (ctenidium) with the...

pila overview afropomus asolene felipponea lanistes marisa pila pomacea saulea the old world (africa and asia) genus pila contains around species. the type species is pila ampullacea (linné, ). the status of some at least pila members is still unclear and it remains to be seen wether or not these snails

could be classified in a seperate genus: turbinicola (annandale & prashad, ) or that it's more justified to create a sub-genus pila (turbinicola). the type species is turbinicola saxea (annandale & prashad, ). older pila snails have a calcified inside of the operculum (shell door). this is characteristic...

apple snail (ampullariidae) genera and species. colour genes the common spiketopped apple snail or pomacea diffusa is know in many colour variations. this page is my effort to clear this a bit out and to help people understand the basic mechanisms that determine the colour variations in these apple snails

. remember, however, that there is not much known about colours in apple snails, and that this page is more a sort of hypothesis of how the possible mechanisms could work. play with the genes: in the interactive example below, one can switch on and off the colour genes. these genes are available in at...
