With only 51 known reef manta rays off Guam’s shores, the death of a male ray named “Streaker” in Tumon is “impactful,” said Julie Hartup, executive director of the Micronesian Conservation Coalition.

“He is one of our main males,” Hartup said. “So to have him gone is definitely going to be felt within the population.”

Streaker was found dead in April after it appeared he had been hit by a Jet Ski or boat, according to Hartup, who was able to identify him from video taken by divers in the area. Hartup said that unfortunately, Streaker's remains could not be located.

Hartup said while the reef manta ray is not on the endangered species list, MCC is working to change that because of their “micropopulation.”

The value of Streaker could be priceless, according to Hartup, who said studies have shown a single ray is worth about $5 million in ecotourism or potential tourism.

Rays such as Streaker, who Hartup estimates was at least 10 years old, can live for up to 30 or even 40 years and reach a length of up to 3 meters long. Female reef manta rays give birth to an offspring every three to five years, she said.

The rays are targeted in Asia and Indonesia for their gills, which are used for medicinal purposes in some cultures.

Hartup said the community can help keep the rays safe by not chasing them. “Let them come to you,” she said.

The reef manta rays are found primarily on the leeward side of the island, she said.

For those looking to do more to help the plight of the manta ray locally, the Micronesian Conservation Coalition offers an Adopt a Manta program where individuals or businesses can pledge money to help support and fund the study of the animal.
