Habitat & Geographic Range
Kleiner Leuchthai
Native to Asia and Europe and South America, inhabiting ecosystems characteristic of the region.
Distributed across Chile, Norway, and Taiwan.
Meldenflureule

The cigar shark, also known as the cookiecutter shark (Isistius brasiliensis), is a small but remarkable shark in the family Dalatiidae, found throughout warm oceanic waters worldwide in tropical and subtropical latitudes. Reaching only 40–50 centimeters in length, it possesses oversized jaws with large, triangular lower teeth arranged in a saw-like series that cut distinctive circular plugs of flesh from much larger prey—including tuna, dolphins, whales, billfish, and even submarine cables and human bodies. It does not kill its prey but instead latches on, rotates its body, and excises a characteristic cookie-cutter-shaped bite. The cigar shark is bioluminescent, emitting a green glow from photophores on its ventral surface that may serve as counter-illumination or to attract prey from below. It undertakes diel vertical migrations, ascending to shallower waters at night and descending to mesopelagic depths during the day. The species is classified as Least Concern by the IUCN, with a vast oceanic distribution and no targeted commercial fishery. It is occasionally taken as bycatch. The geographic epithet brasiliensis refers to Brazil, where early specimens were described, but the species' range is circumglobal in warm oceans. The cookiecutter shark's feeding strategy is one of the most unusual among elasmobranchs.
Meldenflureule
The clover cutworm (Anarta trifolii) is a noctuid moth in the family Noctuidae, order Lepidoptera, with a wide distribution spanning Europe, Asia, Africa, and North America. The species has a characteristic cutworm larva that severs plant stems near the soil surface or feeds on leaves and developing seeds, causing significant damage to crops. Primary host plants include clover (Trifolium), alfalfa, beet, and various other broadleaf crops and weeds, making A. trifolii an agricultural pest of moderate to significant importance in affected regions. Adults are brownish-grey moths with subtle wing patterns typical of the noctuidae family, and like most noctuids, they are nocturnal and attracted to light sources. The species is highly mobile, with adults capable of long-distance migration that enables rapid colonization of new agricultural areas. A. trifolii inhabits a broad range of open habitats including agricultural fields, meadows, steppes, and disturbed grasslands across its extensive range. Its polyphagous larval diet and migratory adult behavior contribute to its wide geographic range spanning multiple continents. In Europe, it is found from the Mediterranean to Scandinavia; in North America it occurs in both Canada and the United States. A. trifolii is classified as Least Concern on the IUCN Red List, with populations considered stable and the species benefiting from the widespread availability of agricultural host plants. Natural enemies include parasitoid wasps and tachinid flies, along with pathogens including nuclear polyhedrosis viruses used in biological control.
