Habitat & Geographic Range

Asiatic elephant

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 9 distinct biome types spanning the Australasia and Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across India, Indonesia, Myanmar, Sri Lanka, and Thailand. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Cigar shark

Habitat

Native to Asia and Europe and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Chile, Norway, and Taiwan.

Asiatic elephant

Smaller than its African cousin, Asiatic elephants range across South and Southeast Asian forests and grasslands from India to Indonesia. Distinguished by their smaller ears, rounded back, and a single finger-like projection on the trunk tip. Deeply interwoven with Asian cultures, they have been used in religious ceremonies and as working animals for millennia. Endangered, with fewer than 50,000 remaining in the wild.

Cigar shark

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.
