Habitat & Geographic Range
Testere
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 6 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.
Distributed across Colombia and Venezuela. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
Epaulard
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 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).
Testere
<em>Pristis pristis</em>, the largetooth sawfish or common sawfish, is a large elasmobranch fish in the family Pristidae, once widespread across tropical and subtropical coastal and freshwater habitats in the Americas, Africa, Asia, and Australia. The species is now documented primarily in remnant populations, including in Colombia and Venezuela. Characterized by its distinctive elongated rostrum lined with paired rostral teeth resembling a saw, the largetooth sawfish typically inhabits shallow coastal waters, estuaries, mangroves, and freshwater rivers and lakes, using its rostrum to detect and stun prey. It is a generalist predator, feeding primarily on fish and crustaceans. The species can reach lengths of up to 7 meters, making it one of the largest of all elasmobranch fishes. <em>Pristis pristis</em> is assessed as Critically Endangered on the IUCN Red List, having experienced catastrophic population declines of over 90% across most of its historical range. Primary threats include overfishing and bycatch, habitat loss through coastal development and river modification, and the international trade in rostral teeth. The species has been extirpated from numerous countries and regions where it was once common. International conservation efforts including fishing bans and habitat protection are underway to prevent further decline and facilitate recovery.
Epaulard
The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
