The previously spotted calf was not in evidence during that interaction. But the observation of Sædis caring for a pilot whale calf marks the first time scientists have directly witnessed maternal behavior between the two species.Īccording to the study, Sædis has not had a calf of her own and was seen interacting with another pod of long-finned pilot whales later in the year. They are closely related to the extinct blunt-snouted dolphins. Between these two species, the animals are found in marine waters all over the world. The genus consists of 2 extant species, the Short Finned Pilot Whale and the Long Finned Pilot Whale. Orcas and long-finned pilot whales regularly interact, specifically during predation events, Newsweek reported. Pilot whales are large aquatic mammals belonging to the Globicephala genus. This specific positioning indicates a maternal relationship, according to Elizabeth Zwamborn, a researcher at Dalhousie University who spoke to Halifax City News.
“The echelon position allows a calf to make fewer tail-fluke movements than when swimming on its own and overcome physical limitations during high-speed travel - in other words, the calf is ‘carried’ by the pressure wave created by the adult’s larger body.” “The orca was swimming with the pilot whale calf in the echelon position, which means the calf was swimming right behind the pectoral fin of the orca,” Marie Mrusczok, the lead author of the paper, told Newsweek. The pilot whales (Globicephala macrorhynchus) are the most common cetaceans in the Canary Islands. The relative positions of the adult orca and pilot whale calf clued the researchers into the special relationship. Short-finned pilot whales, scientifically known as Globicephala macrorhynchus, are members of the dolphin family and one of the second largest, following the killer whale. Other blue whales often grow to be around 90 feet long and weigh around 200,000 pounds. One sea creature that can be spotted is an incredibly unique and astonishing mammal known as the Short-Finned Pilot Whale. No other pilot whales were in the vicinity. Antarctic whales can reach 110 feet long and weigh 330,000 pounds. A female orca known as Sædis was swimming alongside the pilot whale calf and two other pod members. The researchers published their account of the behavior on Feb. Scientists studying orcas off the west coast of Iceland observed an adult orca caring for a juvenile long-finned pilot whale - a unique behavior for both species.
