This serves either as a warning, when they are poisonous or contain stinging cells, or to camouflage them on the klasifikasi invertebrate colored hydroids, sponges and seaweeds on which many of the species are found. Lateral outgrowths on the body of nudibranchs are called cerata.
These contain an outpocketing of digestive gland called the diverticula. Sensory organs and nervous klasifikasi invertebrate edit ] The upper pair of tentacles on the head of Helix pomatia have eye spots, but the main sensory organs of the snail are sensory receptors for olfactionsituated in the epithelium of the tentacles.
