Insects are the most recognised group of invertebrate animals of the Slovinski National Park. Among the hundreds of insects species ascertained here, there has been proved the presence of 30 species being under strict protection - most of them are coleopters Coleoptera. The group of useful and commonly known ants Formicidae is represented by: southern wood ant Formica rufa, red wood ant Formica polyctena. In the late summer at the nearby meadows, there appear the webs in great quantities of a characteristic spider from the family of cross spiders Araneidae - wasp spider Agriope bruennichi (this spider is under strict protection in Poland). The world of mollusca (malaco-fauna) of the Slovinski National Park is represented by almost 70 species belonging to 2 phylums: snailsGastropoda and mollusca Bivalvia. Edible mussel Mytilus edulis common in the Baltic forms the largest submarine bank; on the other hand, freshwaterswan mussel Anodonta cygnaea (being under strict protection) is the most rear mollusc. An inconspicuous crustacean amphipod crustacean Talitrus saltator is also a very interesting invertebrate. This nighttime "beach cleaner" (it feeds with dead organic material) is unfortunately about to extinct, mainly because of being trampled by careless tourists.
Park's water reservoirs are immensely diversified and create convenient conditions for the existence of many fish species, both freshwater and the sea ones. In total, in the sea and fresh waters within the borders of the SNP, there has been proved the presence of approximately 60 fish species as well as 3 lamprey species. In the lakes of the SNP, beside the representatives of ichtchyofauna typically of freshwater character, one can meet sea fish; on the other hand, in the Baltic seaside zone freshwater fish can be found. In the water ecosystems of the SNP there also live bi-environmental species, these are the ones, which spend part of their lives in the sea and the other part in inland waters. To this category belong migratory fish such as salmon Salmo salar, brown trout Salmo trutta and eel Anguila anguila, or the representative of cyclostomatous - sea lamprey Pteromyzon marines.
