Sri Lankan Elephant (Elephas maximus maximus)

  • IUCN Status: Endangered
  • This elephant subspecies in Sri Lanka faces escalating conflict and dangers.
  • Development projects fragment migration routes between protected parks where over 75% of forests were cleared over past decades.
  • With habitats no longer able to support populations, elephants increasingly raid crops causing retaliation killings.
  • Train collisions and wire fences electrocutions kill over 100 elephants annually.
  • Urgent mitigation is required to ensure coexistence and prevent extinction of Sri Lanka’s beloved tuskers.

Sumatran Orangutan (Pongo abelii)

  • IUCN Status: Critically Endangered
  • The Sumatran orangutan numbers under 14,000 as palm oil and paper pulp deforestation destroys over 80% of the Indonesian island’s old-growth in two decades.
  • Forest fires threaten remaining peat swamps refuge habitat.
  • Females birth an infant only once every 8-9 years, meaning habitat with adequate fruit for orangutan survival requires protection for generations.
  • Without vastly expanded habitat conservation of intact forests, the iconic ape risks extinction.

Tiger (Panthera tigris)

  • IUCN Status: Endangered
  • Endangered The tiger faces extinction across Asia from overhunting and habitat loss over past centuries.
  • Nine subspecies reduced to surviving in fraction of historic range, with three subspecies already extinct.
  • Wild tiger populations plunged over 95% to dangerously low population numbers around 4,000 total remaining across fragmented pockets and isolated reserves.
  • Captive tigers cannot restore wild populations alone.
  • Conserving interconnected landscapes and preventing poaching are paramount to safeguard the species in the wild.

Whale Shark (Rhincodon typus)

  • IUCN Status: Endangered
  • Endangered Despite growing tourism interest, the majestic whale shark faces extensive threats from fisheries.
  • As filter feeders, whale sharks are vulnerable to entanglement and boat strikes.
  • But the iconic species’ mass migration events make monitoring and protection difficult.
  • Additional survey work to identify key sites and behavior patterns is vital to balance fishing industry concerns with enforcement policies that enable whale shark population resilience worldwide.

White Rhino (Ceratotherium simum)

  • IUCN Status: Near Threatened Both white rhino species the Northern & Southern white rhino faced catastrophic poaching pressure reducing wild populations to under 20,000 today across southern African nations.
  • Intensive protection and oversight facilitated slight population recovery for the southern subspecies.
  • However with only two aging northern white rhinos surviving under guard, the subspecies is functionally extinct.
  • Stopping wealthy criminal trafficking networks financing rhino poaching is paramount to protect all surviving wild rhinos.

Whooping Crane (Grus americana)

  • IUCN Status: Endangered
  • Endangered Whooping cranes stand five feet tall with immense white wings spanning over seven feet.
  • Hunting and habitat destruction decimated populations down to just 21 wild birds by 1941.
  • Their migration route from Canada to Mexico spans thousands of miles over land and water.
  • Conservation efforts established a second flock taught migration routes by guiding aircraft.
  • However with only about 800 across 2 isolated wild breeding populations today, whooping cranes remain vulnerable to continue their ancient migrations.

Yellowfin Tuna (Thunnus albacares)

  • IUCN Status: Near Threatened
  • A prized target species for industrial tuna fisheries, yellowfin stocks declined over 50% since 1950 in the Atlantic and Indian Oceans.
  • As apex open ocean predators, managing yellowfin populations and long term recovery requires balancing multi-national commercial fishing interests with scientific biomass data.
  • This recognizes the interconnected impacts tuna overexploitation has on broader pelagic ecosystems.
  • Rebuilding yellowfin abundance ensures future fish supply and helps mitigate climate influences on oceanic food chains.

 

 

Albacore Tuna (Thunnus alalunga)

  • IUCN Status: Near Threatened
  • Albacore tuna are found widely in tropical and temperate waters globally.
  • They are the only tuna that do not have heat exchangers which allow them to maintain muscle temperature above water temperature.
  • Young albacore feed on jellyfish and fish larvae before transitioning to fish and cephalopods.
  • The albacore population has faced concerning declines recently due to high fishing pressure, with harvest rates above maximum sustainable levels.

Beluga (Delphinapterus leucas)

  • IUCN Status: Near Threatened
  • Belugas inhabit Arctic and sub-Arctic waters.
  • They are highly social, living in pods that can contain over 1,000 members.
  • Belugas lack a dorsal fin and use sonar for navigation and finding holes in sea ice.
  • Overhunting previously devastated numbers, and current threats are climate change, pollution, and habitat disturbance.
  • Some populations are recovering under protection while others remain endangered.
