Thousands of 'penis fish' exposed on California beach

LOS ANGELES, United States — Thousands of marine worms dubbed "penis fish" for their shape and color appeared this week on a California beach after a strong winter storm exposed them.

The creatures -- more commonly known as fat innkeeper worms -- covered Drakes Beach, 50 miles north of San Francisco.

Despite their eye-catching appearance, the pulsating worms which reach around 10 inches are adept at digging U-shaped burrows on beaches and marshes, using the tunnels to catch food.

Found almost exclusively in California, they are themselves considered a culinary delicacy in South Korea, with reputed aphrodisiac effects.

"Yes, the physical design of the fat innkeeper worm has some explaining to do," wrote biologist Ivan Parr. "But the fat innkeeper is perfectly shaped for a life spent underground."

Parr explained in a column on the Bay Nature website this week that fossil evidence of the animals dates back at least 300 million years.

"They are preyed on by otters, flounders, sharks, rays, gulls, and humans," the latter of whom eat them as sashimi, fried or grilled.

In this case the worms were caught out by heavy rain.

"We're seeing the risk of building your home out of sand," noted Parr.

"Strong storms... are perfectly capable of laying siege to the intertidal zone, breaking apart the sediments, and leaving their contents stranded on shore.

The beach is named after Francis Drake, who is believed to have landed here in 1579 during his circumnavigation of the globe.

'Penis-head' fish discovered in Vietnam

HANOI -- A new species of fish with a penis on its head has been identified in the Mekong Delta in Vietnam, researchers said on Wednesday.

Phallostethus cuulong is the newest member of the Phallostethidae family -- small fish found in Southeast Asian waters that are distinguished primarily by the positioning of the male sexual organ.

Male phallostethids have a copulatory organ, termed the priapium, under the throat for holding or clasping onto females and fertilizing their eggs internally, according to conservationists.

"We have scientifically identified a new penis-head fish in Vietnam," researcher Tran Dac Dinh from Can Tho University told AFP.

The fish was known to Vietnamese people in the Mekong Delta but had not been described scientifically before a team identified the species last year, he said.

Greenpeace urges action on slumping tuna stocks

BANGKOK — Greenpeace Wednesday accused the tuna industry of failing to stop the decimation of fish stocks, and called for an end to fishing methods that also accidentally snare turtles, dolphins and sharks.

Five tuna species are classed as “threatened” or “near threatened” with extinction due to overfishing, according to the Red List of Threatened Species, prompting environmental groups to appeal for fewer industrial-scale boats.

As big players in the multi-billion dollar industry gathered for a trade conference in Bangkok, Greenpeace urged tuna brands to source fish sustainably and end “destructive” fishing methods that see other marine life caught.

“It’s an urgent situation. There are simply too many boats… there needs to be a radical cut if we are going to reverse the decline in stocks,” Sari Tolvanen, a campaigner with the environmental group, told AFP.

“You would think the industry would be concerned about declining stocks, but it’s sitting on its hands.”

Greenpeace says tuna populations can rebound if they are given adequate protection.

The group wants a ban on “fish aggregating devices” that lure marine life into vast bucket-like nets with the result that 10 percent of each catch is made up of species other than tuna.

The tuna industry—from the factory-sized boats to supermarkets—says it recognizes the problem of dwindling stocks and follows quotas limiting catch to mature fish in waters where stocks are abundant.

In the United States, the world’s largest canned tuna market, major brands have pledged to work with their suppliers to reduce the amount of marine life netted accidentally.

In-Soo Cho, chief executive of StarKist, the U.S.‘s largest tinned tuna firm, urged the Bangkok conference to recognize how “precious this limited source of food is,” but warned plunging tuna prices threatened profits.

The Atlantic bluefin species, which can live to 40 years old and grow to more than four meters long, is in the gravest danger of disappearing with stocks estimated in some areas to have halved over four decades.

It is so highly prized by sushi-loving Japanese that a 269-kilogram fish went for a record 56.49 million yen in January auctions.

International agreements to tighten fishing controls are coming into effect, with the European Union, whose waters provide 60% of the global haul of bluefin tuna, mulling laws to protect the endangered species by slashing quotas.

But they can do little to prevent illegal fishing of at-risk species, which also include bigeye, classified as vulnerable, along with yellowfin and albacore, both ranked as near threatened.

“As with any industry there are bad actors,” said Susan Jackson, head of the International Seafood Sustainability Foundation (ISSF)—a coalition of conservation groups, scientists and the tuna companies.

“But we must aim to prevent tuna stocks and their ecosytems being exposed to unnecessary pressure,” she said, adding the industry will still “thrive” with tightened controls on catches.

One ISSF idea is to equip boats with tablet computers to record hauls and help build a detailed picture of global tuna stocks and the scale of accidental catches, she added.

Five main species of tuna make up the annual worldwide catch of 4-4.5 million tons.

Destined mainly for supermarket shelves, the abundant skipjack accounts for 60% of the total.
