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.

Colonial tunicate

Habitat

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

Range

Distributed across Mexico, Norway, Sweden, and United States.

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.

Colonial tunicate

<em>Symplegma reptans</em> is a colonial tunicate in the family Styelidae with known occurrences in Mexico, Norway, Sweden, and the United States. This species has not been evaluated by the IUCN. Colonial tunicates in the genus <em>Symplegma</em> form encrusting sheet-like colonies on hard marine substrates, including rocks, shells, and artificial structures, in shallow coastal environments. Each colony is composed of multiple filter-feeding zooids embedded in a common tunic, through which nutrients and metabolites are distributed. The presence of <em>Symplegma reptans</em> across both the North Atlantic and Pacific coastal regions suggests either a wide native distribution or a history of introduction through maritime vectors such as ballast water and hull fouling. As a sessile filter feeder, this species contributes to water column filtration and nutrient cycling within benthic communities. The reproductive biology of <em>Symplegma reptans</em> likely involves both sexual reproduction via larval dispersal and asexual proliferation through budding within established colonies. Biological traits of this species remain poorly documented in the scientific literature.
