2.4 Comparative Marine Biology:
Seals, Seabirds, Whales and Penguins
The wildlife of Antarctica is uniquely adapted to withstand the harsh
conditions of this region. The seven penguin species are the Adelie, Chinstrap,
Emperor, Gentoo, King, Macaroni, and Rockhopper. The six seal species
are the Antarctic fur, Crabeater, Leopard, Ross, Southern Elephant and
Weddell. Six species of whales belonging to the southern baleen group
make their home in Antarctica for at least part of the year: Blue, Fin,
Humpback, Minke, Sei, and Southern Right. Six different species of toothed
whales are commonly seen in Antarctic waters: Sperm, Orca, Southern Bottlenose,
Southern Four-tooth and Hourglass, and Southern Right Whale dolphins.
There are more than 40 species of flying seabirds and landbirds, with
Skuas, Petrels, Gulls, and Cormorants among the more common. Banding and
recovery studies show that some Antarctic birds travel throughout the
Students will compare and contrast features of several Antarctic animals
Have students brainstorm a complete list of Antarctic animals. Record
list on chalkboard; discard any animals that are not found in the Antarctic!
Discuss methods of grouping these animals, then rewrite list under category
- Working in teams of 3-4, students will research a particular grouping
of animals. Using the Worksheet to organize their findings, students
may also want to add a section-a collection of "Weird" or
"Amazing Antarctic Facts"!
- When the research and chart are completed, teams can present their
- Additional class discussion topics:
- ways animals in Antarctica are uniquely adapted to their environment
- ways in which the wildlife in Antarctica are threatened by outside
- implications if any one species were removed from the food web
Use satellite images of the Southern Hemisphere and references on migration
to trace the migration routes of various species of sea animals and birds
that spend at least part of the year in Antarctica.
