North Atlantic Right Whale: A Species on the Brink.
North Atlantic Right Whale: Urgent Endangered Status
The North Atlantic right whale is one of the most endangered large whales on the planet. Current estimates place the population at fewer than 400 individuals, with NOAA’s most recent abundance estimate around 380 whales. Of those, only about 70 are reproductively active females. This is the demographic that determines whether the species can recover, and their numbers are critically low.
Why Their Numbers Are Falling
Right whales face multiple human‑driven threats, but two stand out as the primary causes of decline.
Entanglement in fishing gear
Entanglement is one of the leading causes of injury and death. Whales can drag heavy gear for months or even years, which leads to exhaustion, deep wounds, infections, and reduced ability to feed or reproduce. Entanglement is a major driver of the ongoing Unusual Mortality Event, which has documented 170 affected whales since 2017, including 43 confirmed deaths, 40 serious injuries, and 87 sublethal injuries.
Vessel strikes
Right whales spend long periods resting or swimming just below the surface making them extremely vulnerable to ships, could be due to the lacking of a dorsal fin, Vessel strikes are a major cause of serious injury and death and are directly tied to population decline.
The Numbers Behind the Crisis
• Approximately 380 whales remain
• Fewer than 400 overall
• Only about 70 breeding females
• Calving intervals have increased from a healthy 3 years to 7–10 years
• Since 2017, at least 43 whales have died in the Unusual Mortality Event
These numbers show a species struggling to replace itself. Even a single death has population‑level consequences.
In early 2026, researchers documented more than 115 individual right whales in Southern New England waters. This represents over a quarter of the entire population. The group included two mothers with calves and the well‑known female Calvin, who has survived eight entanglements and still produced four calves.
These sightings triggered a voluntary Slow Zone, urging vessels to reduce speed to 10 knots to prevent collisions. It was a reminder that even small changes in human behavior can protect the whales that remain.
Right whales evolved for a quiet, predictable ocean. Today they face shifting prey due to climate change, habitat disruption, chronic noise, and high juvenile mortality. Even with protections in place, the species cannot recover unless entanglements and vessel strikes are dramatically reduced.
Why Saving Them Matters
Right whales are more than a symbol of the ocean’s past. Large whales act as ecosystem engineers, helping fertilize phytoplankton that produce at least half of Earth’s oxygen and support global fisheries. Losing them weakens the entire marine system.

The Oceans Gentle Giant: The Whale Shark
ENDANGERED SPOTLIGHT: THE WHALE SHARK
By Amanda — The Ripple Effects Marine Ecosystem Conservation
The same whale shark that recently traveled more than 1,200 kilometers from Madagascar to Seychelles is part of a species now officially listed as Endangered. Its long‑distance journey, tracked by researchers with the Madagascar Whale Shark Project (2025), offered a rare look into the migration corridors these giants depend on. It also underscored a growing concern: even the largest fish in the sea is struggling to survive in a rapidly changing ocean.
Whale sharks are found in warm, tropical waters around the world, from the Indian Ocean to the Pacific. They move between feeding grounds, coastal nurseries, and offshore highways that scientists are only beginning to map. Their size is legendary—reaching lengths of 40 feet and weights of 20 tons—yet their diet consists almost entirely of plankton, krill, and tiny fish filtered through a mouth nearly five feet wide.
Despite their enormous size, whale sharks face threats that their gentle nature cannot protect them from. Many feed at the surface, placing them directly in the path of shipping traffic. Propeller scars are common, and vessel strikes remain one of the leading causes of injury. They are also vulnerable to bycatch in tuna fisheries, where large nets sweep through feeding zones. In some regions, illegal hunting continues for their meat, fins, and oil.
Climate change adds another layer of pressure. Shifts in ocean temperature alter plankton blooms, forcing whale sharks to travel farther for food. Their slow reproductive rate—maturing around 25 to 30 years old—means populations cannot recover quickly from losses. According to the IUCN (2024), global numbers continue to decline.
Whale sharks have no natural predators once they reach adulthood. Their only true enemies are human‑driven: ships, nets, habitat loss, and warming seas. Juveniles may occasionally fall prey to larger sharks or orcas, but such events are rare.
Scientists consider whale sharks a vital indicator species. Their movements reveal the health of plankton systems, the productivity of coastal waters, and the stability of migration routes that many marine animals rely on. They also support eco‑tourism economies that depend on responsible wildlife encounters.
There is still hope. International protections under CITES, expanding marine protected areas, and satellite‑tagging programs are helping researchers understand where whale sharks travel and what they need to survive. Each migration recorded—like the recent Madagascar to Seychelles crossing—adds another piece to the conservation puzzle.
Whale sharks are peaceful, curious, and ancient. Their skin is thicker than a bulletproof vest, and each one carries a unique constellation of spots like a fingerprint. They have crossed oceans for millions of years, long before humans ever charted the sea. Their decline is more than a statistic; it is a warning about the state of the waters we all depend on.
Saving them means protecting the routes they travel, the food they rely on, and the ecosystems that sustain them. The urgency is real, and the window is narrowing. But with coordinated conservation efforts, the gentle giant that crossed an ocean may continue to do so for generations to come.

The Sawfish
Sawfish are among the most evolutionarily distinct and threatened marine animals on the planet. All five species in the family Pristidae are currently listed as Critically Endangered due to rapid population declines across their historical ranges (IUCN, 2024).
Despite their shark‑like shape, sawfish are rays, belonging to the order Rhinopristiformes. Their defining feature — the tooth‑lined rostrum — is both a sensory organ and a feeding tool. The rostrum contains electroreceptors that detect the weak electrical fields produced by prey buried in sediment (NOAA Fisheries, 2023). This adaptation allows sawfish to hunt effectively in low‑visibility coastal waters.
Historically, sawfish occupied tropical and subtropical coastal zones worldwide, including mangrove forests, estuaries, river mouths, and shallow continental shelves. These habitats are essential for juveniles, which rely on sheltered, low‑salinity areas for survival (IUCN, 2024).
Today, sawfish have disappeared from more than 80% of their former range, with remaining strongholds limited to northern Australia and parts of the United States (NOAA Fisheries, 2023).
Sawfish use rapid lateral movements of the rostrum to stun or injure prey such as fish, crustaceans, and mollusks. This feeding behavior influences prey distribution and sediment structure, making sawfish an important ecological component of coastal and estuarine systems (NOAA Fisheries, 2023).
Sawfish declines are driven by several overlapping pressures:
The rostrum easily entangles in gillnets, trawls, and longlines. Bycatch is the leading cause of sawfish mortality worldwide (NOAA Fisheries, 2023) .Mangrove removal, dredging, shoreline development, and altered freshwater flow have destroyed critical nursery habitats. Habitat loss is a major factor in the collapse of sawfish populations (IUCN, 2024).
Sawfish rostrums, fins, and other body parts are sold illegally as curios, trophies, or for traditional uses. International trade of all sawfish species is banned under CITES Appendix I, yet illegal trafficking persists (CITES, 2022).
Sawfish mature slowly, live long lives, and produce relatively few offspring. These traits limit their ability to recover once populations decline (NOAA Fisheries, 2023).
As apex or near‑apex predators in shallow coastal ecosystems, sawfish help regulate prey populations and maintain ecological balance. Their disappearance can trigger cascading effects throughout estuarine and nearshore food webs (IUCN, 2024). Protecting sawfish also protects mangroves, estuaries, and coastal habitats that support countless other species — including commercially important fisheries.
What Recovery Requires
- Enforcement of gillnet restrictions and bycatch‑reduction measures
- Protection and restoration of mangrove and estuarine habitats
- Stronger monitoring of illegal wildlife trade
- Public awareness and science‑based outreach
Sawfish have survived for millions of years, but their future now depends entirely on human action. Conservation efforts in Australia and the United States show that recovery is possible when habitat protection and fishing regulations are enforced.

The Angel Shark
The Angel shark is one of the most unique sharks on Earth, a flat, ray-like predator that spends most of its life buried under the sand. This hidden lifestyle makes it a vital part of the seafloor ecosystem.
The Shark Trust: https://www.sharktrust.org
iSea (Greece): https://www.isea.com.gr
SUBMON: http://www.submon.org
The Angel shark (Squatina squatina) is now critically endangered, a dramatic fall for a species that once thrived across the eastern Atlantic and Mediterranean. Today, the Canary Islands are the last place on Earth where they are consistently seen, a collapse driven by decades of human pressure. Historical overfishing removed huge portions of the population before protections existed. By catch from bottom trawling remains the most destructive threat; angel sharks lie buried in the sand and cannot escape nets, making them “invisible victims”. Habitat degradation from dredging, coastal development, and sediment disturbance destroys the clean sandy seafloor they depend on for camouflage, hunting, and reproduction. Late maturity and small litters means they cannot recover quickly. Angel sharks are keystone ambush predators that help regulate fish populations and maintain the natural rhythm of coastal ecosystems. Losing them destabilizes the entire food web. With over 90% of their historical range lost and only one stronghold remaining, the angel shark is on the edge of functional extinction. Protecting sandy habitats, restricting bottom-contact fishing and supporting conservation programs in the Canary Islands are now the only path forward.
Vaquita
This is the Vaquita (Phocoena sinus), the world’s smallest and most elusive porpoise. They are the most endangered marine mammal on the planet. Unlike dolphins, they don’t leap alongside boats or seek out human interaction. They are quiet sonar-reliant creatures that prefer to stay hidden. This ghost like nature made it difficult for scientists to confirm their existence until the 1950’s. That same invisibility makes protecting them nearly impossible, as they navigate a habitat that has become a battlefield. Unlike their cousins in the cold Atlantic, the vaquita has adapted to the warm, shallow waters of a tiny corner of Mexico. Barely five feet long this “Panda of the sea” only swims in the northern Gulf of California.
THE FINAL TEN:
The vaquita population has fallen from nearly 600 individuals in 1997 to only a handful today. By 2024, surveys estimated just six to eight remained. But recent 2025-2026 monitoring brought a rare sign of hope. Using high-powered “Big Eye” binoculars and an extensive network of underwater acoustic sensors, researchers confirmed between seven and ten vaquitas, including at least one or two calves.
The Urgency:
Even though the Zero Tolerance area was created to protect the last vaquitas, enforcement has never matched the urgency of the crisis. Reports show that illegal gillnet fishing continues inside the protected zone at nearly the same levels as before the ban. Conservation groups and independent investigators have repeatedly warned that the rules exist on paper, but not in practice. In early 2026, a new threat emerged. Mexican regulators proposed shrinking the protected area by more than 85 percent- limiting gillnet restrictions to only the smallest core refuge. Experts warn this would be catastrophic for the species. Conservation biologists describe the proposal as “ an extinction risk the vaquita cannot afford, ”arguing that reducing protection now would undo years of progress. International bodies have also raised alarms. CITES sanctioned Mexico for failing to stop illegal fishing, and a 2025 environmental compliance review found that enforcement in the Upper Gulf remains inadequate. While the government has partnered with groups like Sea Shepard and installed tracking devices on some vessels, these efforts have not been enough to stop illegal nets from entering vaquita habitat.
The message from scientists is clear: the sanctuary must expand, not shrink. The vaquita is still alive, still reproducing, an still fighting- but without strong, enforced protections, even their resilience won’t be enough.
I have to give recognition to the group Viva Vaquita, please look them up at vivavaquita.org their email is vivavaquita@gmail.com there soul purpose is to save the vaquita. Check their Facebook too.
The Cause and Effects
The crisis facing the vaquita isn’t cause by climate change or habitat loss- it comes from the illegal trade in totoaba swim bladders, which can sell for tens of thousands of dollars on the black market. Because vaquitas share the same waters as totoaba, they are caught in the gillnets used to poach these fish. When a vaquita becomes entangled, it can’t reach the surface to breathe and drowns.
For many local fishermen, the situation is complex. Legal fishing often isn’t enough to support their families, while illegal nets offer life-changing income but carry enormous risks. This conflict between conservation, poverty, and organized crime sits at the center of the vaquita’s struggle.
