Though, Obama administration in San Francisco had vowed once earlier that it would shift the Pacific loggerhead to a critical habitat within one year, it has been found that the government has failed in delivering its promise. It is thus, as per a new report that the administration has been facing legal case by conservation groups.

September 2011, the species was listed as endangered when the government said a critical habitat would be designated to ensure its safety. But, failure of the same took it to U. S. District Court on Tuesday, which is also asking for protection of the Atlantic loggerhead.

The latter nests in Florida and is amongst threatened species. However, loggerhead sea turtles are 250-pound reptiles that are long-migrating, swimming some 7,000 miles from Japan to feeding grounds off Mexico and Southern California and sometimes to Bay Area waters.

Fishing as well as water pollution has been taking their lives, thereby considerably reducing their numbers. It is being suggested that they be protected from fisheries and oil spills so their trajectory toward extinction could be reversed.

A spokeswoman for the National Oceanic and Atmospheric Administration Connie Barclay affirmed, "Its biologists have been working steadily on the task. Identifying critical habitat in the marine environment is particularly complex and it can take longer than we want".
