Baleen whale

Some people may not believe this, but whales have been around for over 50 million years; however, they have not always like they do today (WGBH). Scientist have found over seven different species that whales could have originated from. Some species have had four legs with a furry tail; others have had two flippers and a blubbery tail (“The Evolution”) Here are some hypotheses for how whales have became whales: evolution (depending on religion and beliefs) or whales have just always been apart…

fossil of a whale. Whales in the mountains How did the whale get there? It's not like it decided it would one day swim to the mountains, and it definitely didn't fly there. Luckily, a paleontologist was on the construction site to monitor the area, and found it to be a 4 million year old whale fossil. This creates the explanation for how the whale came to be there. The whale never moved. It was the earth that did. The tectonic activity in the area caused the well-preserved whale to be pushed…

They like to go to the Antarctic Ocean in the summer and MIGRATE north in the winter where it is warmer. Their APPERANCE grayish blue with tiny eyes. Their teeth are called baleen it is the same thing as your…

Blue whales are interesting animals. The physical characteristics of blue whales set them apart from many animals. The habits of blue whales, including their diet, migration, and mating, are unique. The endangerment of blue whales has been a changing topic over the years. Blue whales are the largest animals on Earth today, they even beat the dinosaurs. A blue whale weighs about 200 pounds and it’s length is about 3 school buses back to back, meaning it can range from 82 to 105 feet.…

The Humpback Whale Having no teeth has its disadvantages. Instead of having teeth like my distant cousins, the killer whales, who have the privilege of having a jagged row of teeth, I use my baleen to filter minuscule plankton, krill, and small fish from the water. Right now, I am traveling with a group of whales (called a pod) from Alaska to the warm waters Hawaii, with the intention of finding a mate. A small school of fish swim below me, their color so dim that they blend in with the water.…

CLASSIFICATION AND FUN FACTS ABOUT DOLPHIN 10-B SOPHIA LEE REBECCA CZEKALSKI/ VICTORIA MORGAN Dolphin’s kingdom is Animalia. Spinner dolphins are multi-cellular and heterotrophic so they are classified under Animalia. This means they rely on other organisms for food. The cells that frame these animals don’t have a cell wall and most of the cells are organized into tissues, which are then put into particular groups of organs for function. Dolphins can take part in many complex…

impact has lead Eubalaena glacialis, or the North Atlantic Right Whale, population to be classified as critically endangered. Habitat fragmentation, fishing entanglement, whaling, and shipping are of the main direct human impacts that have affected the North Atlantic Right Whale population. This leads to a decrease in population because of mortality, injury, or other health impacts. Despite conservation efforts the North Atlantic Right Whale population has not seen much growth with estimates of…

The mammalian order Cetacea is composed of two parvorders, the Odontoceti (toothed whales) and the Mysticeti (baleen whales). They compromise of over 80 known living species of whales, dolphins and porpoises (Reiss & Marino, 2001; Simmonds, 2006). The compelling sets of characteristics they have acquired over their 55-60-million-year evolution including echolocation ability and complex social organisation (Hof, Chanis, & Marino, 2005) have created great belief that this order contains some of…

Sharks: Killing Machines? People across the world are stereotypical about sharks, some people think sharks are large man-eating monsters that live to kill, and many people believe that if a shark spots them they will automatically attack without hesitation. This is why I have decided to take the time and do some research and clear up the false information about sharks, since beginning my research I have uncovered that sharks are only known to attack humans when confused or curious. The more I…
