torpedo ray

Ever hear of the torpedo fish? It was popular in Medieval bestiaries. I think that's where they actually got the weapon's name from.

It’s the torpedo ray! Its name comes from the same word that gives us “torpid”.

A big win for the oceans: Bay Ternay is saved!

It is with a very happy heart that I write this happy ocean story. As you may have read, I took a year off after graduating from Boston University in 2011, and I moved to the Seychelles Islands to work with an NGO on coral conservation. Our camp base was located in Bay Ternay, which is located on the main island of Mahe. 

The Bay is honestly my favorite place in the whole world. It was established as a marine park in 1979, and it is paradise, and a place I will hold forever dearly in my heart.  With no direct coastal road,and tricky access, this park retains its exclusivity and natural beauty. Mangroves, seagrass beds, and extensive coral reefs constitute the park… Anything you could think of, I have probably seen in this park: whale sharks, manta rays, schools of hundreds of devil rays, humphead parrotfish, hundreds of green and hawksbill turtles,squids,  dolphins, sharks, torpedo rays, moray eels, guitarfish, groupers… It’s all there. The biodiversity of the place is unreal.

The 1998 El Nino event was devastating for corals all around the world.  Water temperatures were up to 4C above normal seasonal maximum, and exceeded 30C over a significant period of time. Seychelles experienced about 90% coral mortality. The NGO I worked for found that coral cover increased from 10.25% in 2005 to 36.42% in 2012 on reefs across Mahe. Coral cover inside marine parks was much higher than outside them. The Bay was recovering extremely well.

Unfortunately, the land had been sold to Emirates in 2007, which had huge plans of building yet another 5 stars resort, meaning the Bay would be completely dredged and destroyed to accommodate for the private residences, spas, and marinas. The Seychellois fought for the preservation of this unique place. They recognized the importance of biodiversity and marine ecosystem for not only the ocean but for the economy of the country. The island did not need another huge hotel, while many remain half-full most of the time. Many tourists visit Seychelles for its natural resources and diving. But it was hard for them to be heard. And I was about to explode sitting on my couch, not knowing what to do thousands of miles away to protect the place I love. 

(This was Emirates’ projected resort constructions. As you can see, the coral reefs, seagrass and mangroves would have been entirely destroyed).

Last week, the greatest news came to me. Perseverance won. The President of Seychelles put his foot down and stopped the project from going forward due to its high environmental consequences. 

“ All the scientific arguments suggest that such a project will affect the environment of the area. Naturally, as the President of this country, it is my duty and responsibility to take the best decision in the interest of the Seychellois people, and for the protection of our heritage. I have decided that there will be no such project at Cap Ternay.“

I literally cried tears of joy. The thought that I may not be able to ever go back to that place was making me sick to my stomach. But now it’s safe! The ecosystem will continue to recover, and all the marine life will continue to grow and prosper. I applaud the government of Seychelles, but mostly I applaud all the citizens that never gave up since this project came to light.

I know this may not mean a lot to you guys, but this just goes to show that anybody can be heard and can make a difference for places or causes that do matter. I hope you all get a chance to travel and explore the Bay, and fall in love with it like I did.

The Pacific Electric Ray, Torpedo californica.

The Pacific Electric Ray is found only in the west coast of the United States. Typically found in sandy bottoms, rocky reefs, kelp beds and occasionally we will catch them aboard the R/V Robert G. Brownlee in the San Francisco Bay Estuary. Basic characteristic of this species is their round mobile body that has a very large first dorsal (top) fin and kidney shape electric organs on the side of its head. If provoked these species are able to control a charge causing numbness in humans and stuns its prey. This charge can measure up to 50 volts!

Like most chondrichthyes (cartilaginous) fish they posses pores (ampullae of lorenzini) that sense magnetic fields given off by other living organisms. Like our local leopard sharks these rays are ovoviviparous. Ovoviviparous is the process in which the embryos (feeding on the nutrient in the yolk sack) develop inside eggs that are held with in the mother. The mother is able to produce a litter of offspring (approximately 20). Starting around 7 inches, these unique species can grow up to 36 inches (males) and 54 inches (females) and living as long as 24 years.

Marbled Electric Ray (Torpedo marmorata)

Electric rays are an order of marine cartilaginous fish known for their ability to generate electrical discharges. The shock can be used to stun prey and predators, and can range from 8 to 220 volts depending on the species (which is comparable to dropping a mains-powered hair dryer into a bathtub.)

The ray produces its electricity with a pair of specialised organs located on either side of the head, which consist of 400-600 columns. Each column is composed of a stack of around 400 gelatinous ‘electroplates’ which function like a battery connected in a parallel circuit.
