Explain to students that each colored line represents an actual North Pacific blue whale's migration. Two examples of their behaviors include geotropism, the growth of plants against the force of gravity and phototropism, the growth of plants toward the light. For animals, seasonal migration usually refers to movement to a warmer climate during the winter and a cooler climate during the summer. “Humpbacks arguably make the longest documented migration of any mammal,” says one marine biologist.
Privacy Notice | Blue whales can dive for about 10-20 minutes each time and not in really deep one, and its only about 100 metres. Students study whale migration routes using a map scale. On the west coast, blue whales can be seen feeding in the summer months. Write their responses on the board, then refer to their list and ask: Which of these animals use the ocean during their migration?
This species therefore classified into A1 for endangered and it means critically endangered. Unfortunately, this dilemma didn’t last very long and in the 1860’s boats and harpoons were designed specifically to capture large whales and put into production. The competition still continue because they got lot money from blue whales and they do that until near extinction. Organisms travel great distances in search of food, mates, or places to raise their young. In the Northern Hemisphere, they can be seen in the northeast Pacific, from Alaska to Costa Rica, and migrate towards the northwest of the Pacific too. The gentle giant of the sea, the blue whale is instantly recognisable with a long, streamlined shape, mottled blue or grey back and pale underbelly. Without more information about where and when these whales are traveling, it can be difficult to keep these populations safe. Blue whales is the largest animal in the world (larger than elephant though) and during 20th century was almost exterminated due to commercial whaling. Laminate the individual sheets of the MapMaker Kit map so you can re-use it for several years.
Explain that many marine organisms migrate because of seasonal environmental changes. Although often overlooked, plants also have unique behaviors. On the West Coast, the Eastern North Pacific stock of blue whales is thought to winter I the waters off of Mexico and Central America, and feed during the summer in the waters off of the coast of the western United States. Many species of marine animals migrate seasonally, annually, or several times over the course of their lifetimes. Even blue whales easily found in all oceans in the world, their populations had varied challenge, except in the North eastern Pacific (include Alaska down to Central America) population of blue whales is in dangerous situation and only in there the population is increase. However, despite their massive size and weight, blue whales and their travel patterns remain largely a mystery to scientists all over the world. Explain to students that each colored line represents an actual North Pacific blue whale 's migration. Ask students: Why do animals migrate? Ask: Why did the three whales travel different distances and different places? Any interactives on this page can only be played while you are visiting our website.

Females give birth to a single calf about 7m long and weighing 2.5 tonnes. Have each group draw their whale's migration route on a printed World Physical MapMaker tabletop map. movement of a group of people or animals from one place to another. In 1904-1905, first blue whales was taken off in South Georgia. ... where you can get a glimpse of blue whales, finback whales, humpback whales and orca whales, along with other marine mammals.
