The Gulf of Mexico Rice’s whale, one of the rarest marine mammals on Earth, is being pushed toward extinction by an industry with few guardrails and growing power. Fewer than 100 individuals remain, and the main threat to their survival comes from fossil fuel exploration and the vessels that service offshore drilling sites in the Gulf.

Unlike migratory whale species, the Rice’s whale doesn’t leave the Gulf. It lives, feeds, mates, and gives birth in these waters. Its limited range makes it especially vulnerable, Reuters reports. Vessel strikes alone—resulting from the constant back-and-forth of oil and gas support ships—are projected to kill nine whales and seriously injure three more over the next 45 years, according to a new federal analysis.

Drilling activity blocks whale feeding and breeding grounds.

New Drilling Rules Boost Output, But at What Cost?

A recently implemented change by the U.S. Interior Department expands the allowable pressure differential for oil extraction between reservoirs from 200 psi to 1,500 psi. Officials estimate this deregulation could unlock an additional 100,000 barrels of oil per day in the Gulf over the next decade. But environmental advocates argue that the regulatory rollback increases risk—not just to workers, but to fragile marine life.

"This change makes more money for paper pushers, but makes the work more dangerous for tool pushers out in the water," Scott Eustis of Healthy Gulf told Reuters. And the environmental costs could be profound.

Oil and gas ships strike whales and kill them.

Government Failures and Legal Battles

In 2024, a federal court ruled that the government’s prior biological opinion—an assessment required under the Endangered Species Act—failed to adequately protect marine species. That court decision forced the National Marine Fisheries Service to revise its approach to managing oil and gas activity in the region. The court cited the agency's flawed assumption that another catastrophic spill like the 2010 BP Deepwater Horizon disaster was unlikely, despite its own data suggesting otherwise, Earthjustice reports.

But even after the ruling, conservationists say the revised assessment still falls short. It permits harmful operations with little more than theoretical safeguards. Earthjustice and other advocacy groups filed another lawsuit in 2025, arguing that the new biological opinion once again fails to protect critically endangered Rice’s whales and other marine life like the Kemp’s ridley sea turtle.

Court rulings have demanded stronger whale safeguards in the Gulf of Mexico.

Industry Pushback Versus Environmental Urgency

The National Ocean Industries Association (NOIA), a trade group representing offshore energy producers, criticized the “jeopardy finding” for Rice’s whales in the latest biological opinion, calling it inconsistent with science and economically disruptive. NOIA president Erik Milito defended the Gulf's energy industry as environmentally responsible, MarineLink reports, saying it generates low-carbon oil and supports coastal conservation efforts through federal revenue sharing programs.

But scientists disagree. More than 100 experts have warned that without stronger protections, the Rice’s whale could become the first great whale species to go extinct due to human causes. The Center for Biological Diversity stresses that even the death of a single breeding female could lead to population collapse.

Industry pressure is weakening science-based protections.

A Species on the Brink

Rice’s whales are particularly vulnerable because they spend significant time near the surface. That trait, combined with the noise pollution from seismic air guns and heavy vessel traffic, disrupts their communication, navigation, and ability to care for young. The current biological opinion, while acknowledging these threats, fails to mandate meaningful mitigation measures. It projects thousands of sea turtle deaths and serious harm to sperm whales, manta rays, and other imperiled species, yet still allows oil and gas activity to proceed.

As oil exploration pushes farther offshore and deeper below the seabed, the potential for devastating accidents grows. But so far, federal oversight has trailed behind industrial ambition.

The Rice’s whale is listed in NOAA’s “Species in the Spotlight” initiative for critically endangered animals in need of immediate, targeted action. That action has yet to materialize in policy strong enough to reverse its decline. As lawsuits mount and protections remain weak, the fate of this elusive whale—and the broader Gulf ecosystem—hangs in the balance.
