NARWHAL:

The narwhal is famous for its spiraled tusk that can extend two to three meters. The tusk is mostly an attribute of males, although some females may exhibit one as well. The function of this unusual tooth has sparked scientists' curiosity, and it is now believed that the tusk has significant sensory capabilities and may contain up to 10 million nerve endings.  [Less] [Link to this slide]

TRACKING:

Jack Orr and his research team remove the excess attachment cables after looping and swaging them around the pins used to attach the satellite transmitter tag through the dorsal ridge of a narwhal in the North Baffin Island region....[More]

TRACKING:

Jack Orr and his research team remove the excess attachment cables after looping and swaging them around the pins used to attach the satellite transmitter tag through the dorsal ridge of a narwhal in the North Baffin Island region. The tags will help better understand where narwhals go.  [Less] [Link to this slide]

STRESS-FREE?:

Once a narwhal is captured it takes several experienced and focused people to take blood samples and other measurements as well as attach the satellite tags. The process must be fast to minimize stress to the narwhal. Although the animals usually remain calm, they can sometimes put up a fight, especially if a female is captured and is anxious to find her calf in the vicinity. Holding the tail firmly is particularly important.  [Less] [Link to this slide]

RELEASE:

The research team is getting ready to release a narwhal after attaching the satellite tag and taking other measurements. This is a critical moment, and the team needs to be in control. The narwhal is anxious to go and will try to roll and swim away upside down, which can damage the tag in shallow water.  [Less] [Link to this slide]

The narwhal's molting skin is softer in texture than its typical skin, and the animal shows premolting signs over most of its body (close-up of narwhal molting).

DATA:

The Inuit are an integral part of narwhal research tagging expeditions in Nunavut. After the narwhal has been released, Sandie Black (left), head of veterinary services at the Calgary Zoo, goes over data recorded during the tagging process with Natasha Mablick and Syzula Ikkidluak....[More]

DOUBLE TUSK:

In Pond Inlet the double tusk of a narwhal. Double-tusked narwhals are most commonly males although females can also have them. They are rare, and it is estimated that approximately 1.5 percent of narwhal are double tusked....[More]
