The Killer Whale (passage adapted from NOAA and Ocean Today)The killer whale, also known as an orca, is the largest member of the dolphin family. They are one of the mostrecognizable marine mammals with their distinctive black and white bodies. Orcas have the largest dorsal finof any marine mammal. Orcas have anywhere from 40 to 56 interlocking teeth - each one around threeinches long. Their teeth are conical shaped and used for ripping and tearing, but not for chewing. They onlyhave one set of teeth and their teeth are not replaced once lost. Orcas are also conscious breathers. Thismeans that they have to remember to take a breath every time they need air. Orcas swim to the surface ofthe water and then breathe by opening the muscular flap of the blowhole. When closed, the blowhole iscompletely airtight. A killer whale uses its paddlelike pectoral flippers to steer and stop. A killer whale'spectoral fins contain 5 digits much like the fingers on a human hand. Their skeleton is made of both bone andcartilage.33550killer whale, or orca(Orcinus orca)length 8 m (26 ft)Which organisms are more closely related?The killer whale and the megalodon.The great white shark and the megalodon.None of the organisms are closely related.The great white shark and the killer whale.SourceWhich statement does NOT accurately compare the megalodon to the other the modern-day organismsThe great white shark and the megalodon share similar characteristics in their teeth pattern, skeletal structure, and method for obtaining oxygen.The great white shark is smaller in size as compared to the megalodon.O The killer whale and megalodon are similar in size.The killer whale and the megalodon share similar characteristics in their teeth pattern, skeletal structure, and method for obtaining oxygen.Which statement does NOT accurately compare the megalodon to the other the modern-day organismsThe great white shark and the megalodon share similar characteristics in their teeth pattern, skeletal structure, and method for obtaining oxygen.The great white shark is smaller in size as compared to the megalodon.The killer whale and megalodon are similar in size.The killer whale and the megalodon share similar characteristics in their teeth pattern, skeletal structure, and method for obtaining oxygen.1 metre3 feet© 2010 Encyclopædia Britannica, Inc. Scientists use physical evidence to infer evolutionary relationships between seemingly different organisms and between modern and extinct organisms. You will analyze examples ofanatomical evidence and embryologic development to explain these relationships.Use the reading below to answer questions 1 and 2.The Megalodon (passage adapted from The Smithsonian)The Megalodon was the largest fish ever known. Its appearance is described as a streamlined yet powerfultorpedo-shaped fish with a conical snout, large pectoral and dorsal fins, and a strong crescent-shaped tail.The Megalodon had many rows of teeth. Megalodon teeth are triangular, serrated, and symmetrical. Theirteeth constantly shed and were replaced with new ones. The Megalodon obtained oxygen by continuouslyswimming to push oxygenated water over its gill slits on both sides of its head. Their skeleton was mostlymade of cartilage (a hard but flexible material). Cartilage is much lighter than bone and allowed the Megalodonto stay afloat and swim long distances while using less energy.The Great White Shark (passage adapted from The Smithsonian and NOAA)The Great White Shark (passage adapted from The Smithsonian and NOAA)Shark ancestry dates back more than 400 million years. These animals are uniquely adapted to their oceanenvironment with six highly refined senses of smell, hearing, touch, taste, sight, and even electromagnetism.The torpedo shape of the great white is built for speed. They can have up to 7 rows of triangular, serratedteeth. Great White Sharks use their gills to extract oxygen from the water. They are also a special type offish known as "elasmobranchs", which translates into fish made of cartilage-based tissues. Their cartilaginousskeletons are much lighter than true bone.The Killer Whale (passage adapted from NOAA and Ocean Today)The killer whale, also known as an orca, is the largest member of the dolphin family.
