Habitat & Geographic Range
Alequim
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.
Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Common Elephant Tusk
Native to Europe, inhabiting ecosystems characteristic of the region.
Distributed across Denmark, Norway, and Sweden.
Alequim
O tubarão-branco é o maior peixe predador da Terra, podendo atingir 6 metros de comprimento e 2.000 kg, habitando águas costeiras e oceânicas frias em todos os principais oceanos. São predadores de topo que empregam ataques de emboscada por baixo, direcionados principalmente a mamíferos marinhos, peixes de grande porte e aves marinhas. Apesar de sua terrível reputação, ataques não provocados a humanos são extremamente raros. Classificado como Vulnerável (VU), com populações em declínio devido ao corte de barbatanas, captura acidental e pesca direcionada, apesar das proteções legais vigentes em muitas jurisdições.
Common Elephant Tusk
<em>Antalis entalis</em>, the common elephant tusk, is a marine mollusc in the class Scaphopoda, family Dentaliidae, classified as Least Concern by the IUCN Red List. The species is native to European waters and has been documented in Denmark, Norway, and Sweden, inhabiting subtidal and deep benthic zones of the northeastern Atlantic Ocean and North Sea. As a scaphopod, <em>Antalis entalis</em> is characterized by its distinctive curved, tusk-shaped shell that is open at both ends, allowing the animal to partially burrow vertically into sandy or muddy substrates with only the narrow posterior end projecting into the water column. The species feeds on foraminifera and other microscopic organisms in the sediment, capturing prey with specialized tentacle-like structures called captacula that extend through the broader anterior opening of the shell. Scaphopods have limited locomotion and typically remain partially buried throughout their lives. <em>Antalis entalis</em> plays a role in benthic communities as both a consumer of meiofauna and a prey item for predatory fish and invertebrates. Historically, elephant tusk shells of related species were used as currency and ornament by Indigenous peoples of the Pacific Northwest coast. Biological traits of this species remain poorly documented in the scientific literature.
