Sharks
When many think of sharks, they think of the movie Jaws or a dangerous man-eating fish. In reality, sharks is a large group of fish that includes very small to much larger fish. Some can be harmful to man and others are harmless. To delve into this interesting and diverse group of cartilaginous saltwater fish that have sharp teeth and a bad reputation, ask your questions in this category.

What do people hores and sharks have in common?
Horses and sharks, despite being vastly different animals, share some common traits. Both species possess streamlined bodies that enhance their ability to move efficiently through their respective environments—horses on land and sharks in water. Additionally, both are highly adapted predators in their ecosystems, playing crucial roles in maintaining the balance of their habitats. Finally, both horses and sharks exhibit social behaviors, forming bonds within their groups for protection and social interaction.
Sharks are not extinct primarily due to their adaptability and evolutionary success, having existed for over 400 million years. They possess efficient hunting skills, diverse feeding strategies, and a wide range of habitats, allowing them to thrive in various marine environments. Additionally, their reproductive strategies, such as producing fewer but more developed young, help ensure their survival despite environmental changes. Conservation efforts have also played a role in protecting certain shark populations from overfishing and habitat loss.
What is the evolutionary relationship between sharks and fish?
Bony fish and sharks were, until very recently, thought to have evolved during the Silurian period, after the extremely severe Ordovician-Silurian mass extinction.
But we now have jawless fish fossils (ostracoderms) from the Early Cambrian!
Paleontology science believe bony fish (the very first gnathostome infraphylum) was the first to evolve. But we may be wrong.
Fossil register of life in Earth is VERY, VERY scarce. And even more when we talk about life forms more than 400,000,000 years old...
There are very consistent paleontologic theories to point a common ancestor of bony fish and sharks from the Late Ordovician, and they point to sharks evolving first because of the evolutionary emergence of cartilaginous skeletons, which would be a developement - and a design improvement - of the jawless fish primitive notochord.
But we have not yet found any fossil register of this vertebrate common ancestor.
In the meantime, we still have lampreys from the Early Cambrian with rice and sauce, or «À Bordalesa» (an unique Portuguese delicacy!)...
It depends entirely on the species of shark. For instance, the Great White shark is Carcharodon carcharias, the bull shark is Carcharhinus leucas, the scalloped hammerhead shark is Sphyrna lewini, while the scalloped bonnethead (another species of hammerhead) is Sphyrna corona. There are over 470 species of sharks in the world. Regroup, rethink your question, and reask it.

Are there sharks in lake mishigen?
Supposedly a man caught one there but there were no witnesses to the catch. If there are they would be bull sharks since they are the only shark that can live in fresh water. However they would be extremely few and far between so the chances of seeing one is very slim.
Are there sharks at the San Onofre State Beach?
Actually, they are in the sea. All seas, the world over. The area around San Onofre is no different. While three of the top four shark species (Great white sharks, bull sharks, and tiger sharks) noted for unprovoked attacks on humans frequent the area, your chances of being attacked or killed by a shark is minimal. You really are more likely to be struck by lightning. There are other species of shark, such as Sand sharks, Leopard sharks and Hammerhead sharks that ply these waters.

Will your jack dempsey try to eat your bala shark?
yep your 10 inch jd is going to eat your 15inch bala shark... think about that for a min. not to be rude but research the fish your planning on buying. A jd might eat a baby bala but a goldfish would eat a baby bala, a goldfish would eat a baby jd to. Fish eat smaller fish no matter what the species is. All in all a fullgrown jd and a full grown bala would be fine together.

How deep do sharks go under water?
The way the shark is built allows them to swim so deep into the oceans. The form their body takes makes them the perfect specimen for ocean life. The shark can swim as much as 6000 feet below the sea level.
