The so-called wolphin has been confirmed by scientists after it was spotted on a research trip near Kauai island.
Baird told BuzzFeed News that the team will head back to Kauai in August, where they will try to determine whether the female melon-headed whale seen swimming alongside the "wholphin" a year ago is its mother.
"One of the pair of melon-headed whales seen on two occasions had pigmentation and morphological characteristics suggesting it may be a hybrid between a melon-headed whale and a rough-toothed dolphin", the researchers wrote in their new report.
The team was able to obtain a biopsy, using a crossbow equipped with a special dart that prevents deep penetration and returns a skin sample.
Despite it being a hybrid of a melon-headed whale and a rough-toothed dolphin, scientists have said not to call it a "wholphin". But there is something unmistakably charming about a dolphin and a whale hitting it off and producing dolphin-whale offspring, as has been sighted off the coast of Hawaii.
The term was first used in 1985 at Hawaii's Sea Life Park for a hybrid between a false killer whale and an Atlantic bottle-nose dolphin.
The researchers were in the area to study the marine mammals and other creatures that live in the area around the Pacific Missile Range Facility.
In August 2017, scientists conducted a wide survey of the waters of Kauai in which they observed the whale and dolphin species residing in the area with the help of boat-based efforts and passive acoustic monitoring.
According to the new report, this is the first case of these two species mating.
He said: "That isn't the case, although there are example where hybridisation has resulted in a new species".
'I always thought they were out there in the wild existing - it only makes sense, ' he said.
"It isn't and shouldn't be considered a new species", Robin Baird, a biologist with the research group, told HuffPost in an email. "And to know she has cousins out there in the ocean is an fantastic thing to know".
It's unclear if this is true for this latest hybrid animal.
"To know she has cousins out there in the ocean is an incredible thing to know", said Sea Life park curator Jeff Pawloski in response to the new discovery, which he said was proof of the "genetic diversity of the ocean".
Despite the name, melon-headed whales aren't actually whales - they're part of the dolphin family, and they tend to swim in large pods with hundreds of others of their kind.
The hybrid was only traveling with one companion - a melon-headed whale.
