Much more of a snail can be observed if it is induced to extend fully. The simplest method is to place the shell in water with its aperture facing up. A brief glimpse of behind the head, where the penis is usually located on males, may be had as the snail stretches out to grip the substrate and turn the shell.

This pitcher plant (Nepenthes tomoriana) is endemic to Sulawesi where it can be found growing exclusively on ultrabasic rock substrates. South Sulawesi, Indonesia.
This guy certainly knows the meaning of flamboyant colours.
Metasepia pfefferi has been recorded from sand and mud substrate in shallow waters at depths of 3 to 86 m. The species is active during the day and has been observed hunting fish and crustaceans. It employs complex and varied camouflage to stalk its prey. The normal base color of this species is dark brown. Individuals that are disturbed or attacked quickly change colour to a pattern of black, dark brown, white, with yellow patches around the mantle, arms, and eyes. The arm tips often display bright red coloration to ward off would-be predators. Animals displaying this colour pattern have been observed using their lower arms to walk or "amble" along the sea floor while rhythmically waving the wide protective membranes on their arms. This behavior advertises a poisonous nature, the flesh of this cuttlefish contains a unique toxin. Lembeh Strait, North Sulawesi, Indonesia.
This is the largest of my local Limacodids with regard to length, girth and appetite. Although polyphagous (eat several things), they are most noticeable as voracious banana leaf munchers.
Cup Moth larvae are often highly ornamented and brightly colored. Two main types can be distinguished: larvae armed with rows of protuberances bearing stinging spines called nettle caterpillars, or non-spined forms where the surface of the larvae may by completely smooth, called gelatine caterpillars. The larvae of this family bear no prolegs on their abdominal segments. The larva attaches itself to the substrate by means of an adhesive ventral surface. The movement is like a slug hence their generic name.
A stinging slug caterpillar (like this one) generally bears warning colouration and stinging hairs. These hairs can inject a venom from poison sacs carried at their base that are used as defensive weapons. Reactions can range from a mild itching to a very painful sting.

You will notice I have given each individual a descriptive superhero-style name in the title of the image. This species has been dubbed "Submarine" with its row of blue portholes along its flanks. This is for my own reference mainly because practically none of these caterpillars are identified (maybe even ever formally) and this will allow me to group the growing number of images I have into their like-kinds including the various instars I have captured. The names will be included as tags.
