Hubbs' beaked whale

Hubbs' beaked whale (Mesoplodon carlhubbsi) was initially thought to be an Andrews' beaked whale when discovered by ichthyologist Carl Hubbs; however, it was named in his honor when it was discovered to be a new species. This species has the typical dentition found in the genus, but its main outstanding features are a white "cap" on the head and very extensive scarring. The species is known from 31 strandings and one possible sighting.

Hubbs' beaked whale
  • Size

    They reach a length of 5.4 meters (18 feet) and weigh 1500 kg (3300 lbs) for both males and females. They are around 2.5 meters (8 feet) long when born, the longest in proportion for any beaked whale: 46% of the mother's length.

  • Feeding

    Their preferred diet is primarily deep-water squid, but also benthic and benthopelagic fish and some crustaceans, mostly taken near the sea floor. In a recent study, gouge marks in the seafloor were interpreted to be a result of feeding activities by beaked whales.

  • Life History

    Very little is known about the life histories of beaked whales. There are currently no data available on their reproductive rates.

  • Behavior

    Little is known about their behavior due to the infrequency of sightings (only one known); they probably travel in small groups like the other species. Due to the extreme amount of scars present on adult males, there probably is more male competition compared with other members of the genus.
