Question

5 different species of shark and whale​

Answer 1

Answer:

Sharks

• Cold-blooded (most shark and fish species are cold blooded animals)
• Lay eggs (sharks are known to be able to lay up to 100 eggs during a single reproductive cycle while fish can lay several thousand eggs in a single year)
• Have gills (sharks use to gills to breathe underwater, but can suffocate above the water as they are not designed to live above the surface)
• Sharks swim from left to right (the sharks body is streamlined and well designed for swimming underwater)
• Smaller average size compared to whales (sharks are typically smaller than whales likely burn significantly fewer calories due to being small and cold-blooded)
• Sharks can replace their teeth dozens of times of the course of a lifetime
• Sharks can sense electrical signals of other animals in the ocean.
• Sharks have serrated teeth for hunting (sharks are known for having serrated teeth which they use to bite their prey and tear the flesh off it)

Whales

• Warm-blooded (whales are marine mammals and thus are warm-blooded animals that need to maintain a high calorie diet in order to stay warm and keep sufficient blubber levels)
• Whales have blubber (since whales are warm-blooded they need blubber to keep their vital organs warm when they are in cold environments.
• Give birth (whales give birth to their children rather than laying eggs)
• Have blowhole(s) (whales must come to the surface to breathe and can drown underwater)
• Whales swim by moving their tails up and down (the spine of whales appears to be designed for walking/running rather than swimming, so they move their back/flukes up and down to swim)
• Whales are generally larger than sharks
• Whales have either teeth or baleen plates (not all whales use their teeth to chew their prey and some species will only use their teeth to grab onto their prey and will swallow their food whole)
• Whales have hair (some species are born with hair that falls off shortly after birth)
• Whales produce milk (to feed their young)
• Some whales are equipped with echolocation
