In general, it can be said that these animals are much less completely adapted to living in the water than are the cetaceans,Color-pattern features are useful in taxonomy, even lending themselves to cladistic analysis (,We use cookies to help provide and enhance our service and tailor content and ads. Among extinct Cetacea, the close-spaced succession of Eocene archaeocetes suggests species durations of 1–2 Ma. They are also know to move farther into polar ice fields than other rorqual species.Minkes are the smallest of the finback whales, growing to a maximum of 10.2 meters long. Minkes are fast swimmers. Paper SC/55/O2-revised presented to the IWC Scientific Committee. 1967, 12: 279-291. Marine mammals of the world. These include one bear, the polar bear, and two otters, the sea and marine otters.

The RefSeq genome records for Balaenoptera acutorostrata scammoni were annotated by the NCBI Eukaryotic Genome Annotation Pipeline, an automated pipeline that annotates genes, transcripts and proteins on draft and finished genome assemblies.This report presents statistics on the annotation products, the input data used in … (2001). Cooler regions seem to be preferred over tropical regions.Although not considered "coastal", these baleen whales rarely venture farther than 169 km from land. Marine mammals of the world.

For each whale, the fluke and one lateral side was examined.A total of seven epibiotic species were found: the caligid copepod,Information on the epibiotic macrofauna on large whales has been reviewed repeatedly in the cetacean literature [,The abundance of epibiotic organisms on a host population is affected by a complex interaction of physical and biological factors and changes in the epibiota may serve as a biological indicator of ecosystem shifts that may be difficult to observe by other means.

Of those that are known, Hallas [,Common minke whales are commonly observed in the waters off Iceland between April to November, although their abundance is at its peak in June and July [.The current study, which forms part of a larger co-ordinated programme of collaborative research on the ecology and biology of common minke whales, set out to provide baseline information on the species composition, geographic distribution and abundance of the epibiotic macrofauna on minke whales in Icelandic waters during the summer period.

Peak months for births are December and June. Numbers have also been on the rise since the early 1900's because close competitors (other rorqual species) have been overhunted.A second form of minke whale called the dwarf minke has been found off Australia/ New Zealand/ South Africa.
