As If The Name Shark, Was Not Intriguing Enough
Sharks are some of the most graceful, powerful, and beautiful predators within the sea. Many people have become blinded by Great White Shark hysteria, from movies, and they forget to appreciate the mystery and intrigue, surrounding these fish. Hollywood has implanted an image within our minds that is hard to erase, but through the power of communication, we hope to change that image. Becoming knowledgeable about interesting shark facts will not only help to change the image scorched into your brain, but it will allow you to have a little fun, while learning.
10 Interesting Shark Facts
1. Bigger is not always better
Etmopterus perryi, also known as the dwarf lantern shark, is the smallest known species of all sharks. Fully grown dwarf lantern sharks measure in at a whopping 6 inches (15 cm), on average, when fully grown. This species can be found in the ocean, around Columbia and Venezuela. They usually stay in deeper waters, and sightings have been limited. Dwarf lantern sharks are capable of producing light to attract prey, which is an ingenious tool. Not much research has been done on these amazing fish, but perhaps in spreading this knowledge, we can help spark interest.
2. That is fast
On land, cheetahs are among the fastest mammals alive. They have been clocked at spectacular speeds of up to 75 mph (120.7 km/h). Shortfin mako sharks are among the fastest known for their speed in the ocean. These beautiful and intriguing sharks are estimated to keep steady speeds of about 21.75 mph (25 km/h), but they are also capable kicking it up a notch. They have speed bursts of up to 49.71 mph (80 km/h). That may not compare to the speed of the cheetah, but considering that they have the weight of the ocean around them, this is a remarkable feat. On average, this species of shark grows to about 13 ft (4m) and is still capable of recording these fast speeds.
3. Curiosity like a toddler
Sharks are curious creatures. They act much in the same way as a human toddler. Children are curious by nature, and they continually place items in their mouth. If it tastes good, they may continue eating, but if not, it usually erupts out of their mouth, like an active volcano. This same type of system can be seen in sharks. This is an interesting shark fact because many individuals view sharks in a negative sense, but this technique of learning is impressive. Rather than eating something that does not agree with them, they will often take a “test bite” out of their prey. If it is nasty, they will spit it out, and if not, it is dinner time.
4. Who needs sleep?
Humans need sleep on a daily basis to function properly. According to experts we should get at least 8 hours of sleep per night, if not more. As infants, and toddlers, that number increases dramatically, but the same can not be said for sharks. Sharks never sleep! Saltwater is less dense than fresh water. This means the sharks body is more dense than the water around them, and they can sink. Instead of sleep, they have a process referred to as resting. Sharks become increasingly still during this time, but constant movement is vital to their way of life.
5. Millions of Years
Sharks have been around for an extremely long time. Some fossils that have been examined, have dated back to over 400 million years. Just to put that into perspective, that is before the time of dinosaurs. Life expectancy of a shark, in the wild, is approximately 20-30 years, although, some experts believe that certain species can live up to 100 years. Sharks have adapted, evolved, and remained, when other species have become extinct. That is why this is interesting shark fact number 5.
6. Dental Bills Would Be Outrageous
Teeth, teeth, and more teeth. Sharks are capable of losing teeth at an alarming rate, but replacement teeth grow in quickly. Dental bills for humans can be awfully expensive, and they only have one set of permanent teeth. So, a shark’s dental bill would be unimaginable.
7. Brotherly/Sisterly love
Galeocerdo Cuvier, also known as the Tiger Shark, is an aggressive predator. Females produce many eggs, however, only 2 pups from each litter are born. Tiger sharks have two uteri. Once the first pup is born, it begins eating the other eggs, whether they are fertilized or not. This process continues until 1 pup remains from each uterus, resulting in only 2 pups being born.
8. What in the world?
Although sharks often take “test bites”, some crazy items have still turned up in their stomachs. Shoes, half of a horse, and chairs are some of the wacky items that have been recovered. Despite having a keen sense of smell, their aggressive feeding habits, often cause them to eat items that should not be eaten. In fact, tiger sharks are often referred to as the “garbage cans of the sea”.
9. Over 400 Species
Sharks come in a variety of shapes and sizes. Different species have unique characteristics which contribute to their staying atop the food chain. Some sharks are filter feeders, while others are active hunters. There are some that are small in length, and others that are gargantuan in size. There sheer numbers, and the still unknown species, are what makes this interesting shark fact number 9.
10. Humans are the greatest threats to sharks
Sharks do not have many enemies within the ocean, rather, their enemies come from land. Destroying of habitats, fishing, and shark-finning are all ways in which humans threaten shark populations. Man and fish can live together in harmony, through proper education, communication, and actions.
