BP vs the Dwarf Seahorse

The Center for Biological Diversity filed a petition on Wednesday seeking Endangered Species Act protection for the dwarf seahorse (Hippocampus zosterae)—a victim of myriad troubles in its tiny world:

  • BP’s oil disaster in the Gulf of Mexico
  • Seagrass beds destroyed by shrimp trawlers, pollution, and climate change
  • Commercial collection for aquariums, curios, and “medicine”

These one-inch-long (2.5-centimeter-long) seahorses live only in the shallow seagrass beds of the Gulf, off Florida, and in the Caribbean.

Long before BP unleashed its oil and dispersants, all three regions had been hard hit by destructive fishing practices, lousy boating practices, and pollution. Since 1950, Florida has lost more than half—in some places more than 90 percent—of its seagrass beds. The numbers aren’t a whole lot better for the rest of the Gulf.

The IUCN Red List finds insufficient data—a fact in BP’s favor—to assign a listing to the dwarf seahorse: 

There are no published data about population trends or total numbers of mature animals for this species. There is very little available information about its extent of occurrence or its area of occupancy. There have been no quantitative analyses examining the probability of extinction of this species. As a result, we have insufficient data to properly assess the species against any of the IUCN criteria, and propose a listing of data deficient.

This species may be particularly susceptible to decline. The information on habitat suggests they inhabit shallow seagrass beds that are susceptible to human degradation, as well as making them susceptible to being caught as bycatch. All seahorse species have vital parental care, and many species studied to date have high site fidelity, highly structured social behaviour, and relatively sparse distributions. The importance of life history parameters in determining response to exploitation has been demonstrated for a number of species.

Dwarf seahorses can’t live anywhere but in seagrass. They live only a single year. Whether we have data or not, the truth is BP probably took out most of the 2009 year-class and its 2010 year-class offspring in the northern Gulf last year.

 

 

WHO DOESN’T LOVE A POSITIVE STORY—OR TWO?

“Great journalism really does make a difference in this world: it can even save kids.”

That’s what a civil rights lawyer wrote to Julia Lurie, the day after her major investigation into a psychiatric hospital chain that uses foster children as “cash cows” published, letting her know he was using her findings that same day in a hearing to keep a child out of one of the facilities we investigated.

That’s awesome. As is the fact that Julia, who spent a full year reporting this challenging story, promptly heard from a Senate committee that will use her work in their own investigation of Universal Health Services. There’s no doubt her revelations will continue to have a big impact in the months and years to come.

Like another story about Mother Jones’ real-world impact.

This one, a multiyear investigation, published in 2021, exposed conditions in sugar work camps in the Dominican Republic owned by Central Romana—the conglomerate behind brands like C&H and Domino, whose product ends up in our Hershey bars and other sweets. A year ago, the Biden administration banned sugar imports from Central Romana. And just recently, we learned of a previously undisclosed investigation from the Department of Homeland Security, looking into working conditions at Central Romana. How big of a deal is this?

“This could be the first time a corporation would be held criminally liable for forced labor in their own supply chains,” according to a retired special agent we talked to.

Wow.

And it is only because Mother Jones is funded primarily by donations from readers that we can mount ambitious, yearlong—or more—investigations like these two stories that are making waves.

About that: It’s unfathomably hard in the news business right now, and we came up about $28,000 short during our recent fall fundraising campaign. We simply have to make that up soon to avoid falling further behind than can be made up for, or needing to somehow trim $1 million from our budget, like happened last year.

If you can, please support the reporting you get from Mother Jones—that exists to make a difference, not a profit—with a donation of any amount today. We need more donations than normal to come in from this specific blurb to help close our funding gap before it gets any bigger.
