One-of-a-kind hybrid fascinates scientists

Rare whale-dolphin hybrid discovered in Hawaii, scientists say New Hybrid Whale-Dolphin Discovered Off Hawaii

The marine scientists tagged the hybrid with satellite tracking Global Positioning System, along with a companion, to see where they might go.

Scientists who found the specimen tracked numerous species during a study off the island of Kauai previous year.

"Hybrids among different species of whales and dolphins have been previously recorded, but this is the first case of a hybrid between these two species, and only the third confirmed case (with genetics) of a wild-born hybrid between two species in the family Delphinidae", or oceanic dolphins, Baird said.

Both pigmentation and morphological characteristics suggested it may be a hybrid resulting from a melon-headed whale and a rough-toothed dolphin mating, scientists explained in the new report.

The hybrid was especially rare because of its melon-headed genes: The toothed-whales are rarely seen in these Hawaiian waters, the researchers wrote.

They were doing field work in the waters near Kauai when they spotted a pod of melon-headed whales and rough-toothed dolphins swimming alongside each other.

It didn't, for example, have the rounded head of melon-headed whales, and yet its beak was shorter than those of rough-toothed dolphins. "We were able to get a biopsy sample of the animal" as reported by express.co.uk.

Baird said this is unlikely to be the start of a whole new species of dolphin, however, because male hybrids are often sterile, and because only one of its kind has been spotted so far.

It's unknown whether this new animal - which the researchers named Steno bredanensis - could produce viable offspring, but in any case, one hybrid animal does not make a new species.

So, the bad news is, we don't have a new species of whale-or dolphin-on our hands.

News of the hybrid spotted in the wild during navy-funded research to study the effects of sonar, proves the "genetic diversity of the ocean", Sea Life park curator Jeff Pawloski said.

While some news organizations have described the hybrid as a new species, research biologist Robin Baird says in order for that to happen other things need to occur, including more widespread hybridization.

Killer whales (Orcas) are also Delphinidae or dolphins. "And to know she has cousins out there in the ocean is an fantastic thing to know".

A likely scenario for how the hybrid came to be a melon-headed whale getting separated from its group and ending up travelling with rough-toothed dolphins. For instance, perhaps when the mother was looking for a mate, she was unable to find a suitable one among her own species.

Scientists don't know how old it is but believe it's close to adult age.
