You can tell by their bones.
Without the specific cladogram provided, I can't determine which animal is more closely related to sharks. However, in general, based on evolutionary relationships, animals like rays and skates (which are also cartilaginous fish) are typically more closely related to sharks than bony fish or other vertebrates. If the cladogram includes these categories, look for the group that shares a more recent common ancestor with sharks.
yes. they are closely related to sharks
Sharks and dolphins are not related as sharks are fish and dolphins aquatic mammals. Sharks originate from small fish and dolphins from land living ferret like animals. Their spines both bend in different directions; dolphins move up and down and shraks from side to side. Dolphins are much closer related to dogs than they are to sharks.
shark are scared of dolphin.
They aren't any relationship between them as sharks eat dolphins.
No, they are not. Dolphins are a mammal, and sharks are not.
dolphins enemies are bull sharks tiger sharks dusky sharks and great white sharks.sharks can kill dolphins.
Dolphins VS sharks, hmmm. Sharks are pretty strong but dolphins are better. Sharks have pretty sharp teeths but dolphins are much more smarter faster and can kill sharks by smashing their strong beaks right into the sharks gills. Sharks can swim ten to twenty miles per hour but dolphins can swim up to thirty miles per hour, let's go for the dolphins. Sharks has sharp teeths but dolphins has a really strong beak that can kill sharks. The dolphins is now the winner.
Great White shark,tiger sharks,bull sharks,orca whales
Dolphins are related to killer whales because the are. Asking why is nonsensical. Being related is a simple description of what is. "Killer Whales," proper name Orcas, are the largest member of the dolphin family.
Typically, sharks and dolphins avoid each other. On occasion however, sharks such as the great white will hunt baby dolphins. Dolphins are tough creatures and sharks have learned to ignore them, for the most part.
Dolphins hide from sharks and dolphins can also sense danger.
