A tetrapod is a vertebrate animal with four limbs. "Tetra" means "four" and "pod" means "foot".
Amphibians, reptiles, birds and mammals are all tetrapods; even snakes and other limbless reptiles and amphibians are tetrapods because they descended from animals which had four limbs. Whales and other cetaceans are also tetrapods because they are mammals have two front limbs and the two hind limbs are vestiges.

Yes, sharks have paired fins, including pectoral fins (located on their sides) and pelvic fins (located on their underside). These fins help sharks with stability, steering, and maneuvering in the water.
What is the color of shark's blood?
Shark blood is red due to the presence of hemoglobin and other oxygen-binding proteins, similar to the blood of most vertebrates. However, some deep-sea sharks have adaptations that make their blood appear greenish or even clear to help them camouflage in their environment.
Bala shark's take a long time to grow they grow 8" every year until fully grown. but in order for them to grow big they need room to grow the smaller your tank and the more fish you have in their stops it from growning. when getting fish use the rule 1' per a gallon so you got to think this fish will grow and know how big it will get so you are per pared for it.
Sharks are opportunistic feeders and can feed at any time of day or night, depending on the species. Some sharks are more active at night, while others prefer to feed during the day. Their feeding behavior can also be influenced by factors such as tides, water temperature, and availability of prey.
Sharks are primarily crepuscular and nocturnal feeders, meaning they are most active during dawn and dusk, as well as at night. However, some species, like tiger sharks and great whites, may also hunt during the day. Sharks feed opportunistically and will actively seek out prey when hungry.
What does the spiny dog shark eat?

How many years have sharks been around?

Sharks have been around for about 409 million years but before they evolved they were around for 890 million years. TRUE!
Over 400 million years!
Shakrs have been alive for a very long time. They have swam the waters of earth since about 409 million years ago. This period of time was before our first dinosaurs came to be infact.
most sharks eat from dusk to dawn. If you'll notice, 99.9% of all shark attacks happen after dusk. Need anything else answered? Just contact me at sharkruler5000@gmail.com. I'm a huge shark fan!!!!
What kind of sharks have spots?
Leopard sharks are known for their distinctive spots, which are present along their bodies. These spots serve as a form of camouflage to help them blend in with their surroundings as they hunt for prey.
Do you need to have gills to breathe underwater?
Yes, you do need gills to breathe underwater. Gills process the water through them that makes the water allowed to go through the animal's body without drowning them. Gills are the only thing that keep the animals that live underwater, alive. they also don't make you breath the air in-you breath the oxygen in the water!

Some shark species can swim close to shore in shallow waters, but they generally do not come onto land. Sharks rely on water to breathe and move, so they are not adapted to survive out of the water for extended periods of time.
What is the difference between a dolphin fin and shark fin?
A dolphin fin, also known as a dorsal fin, is curved and typically sits upright on the dolphin's back, aiding in stability and steering. A shark fin, on the other hand, is more triangular in shape and helps sharks maintain buoyancy and make sharp turns while swimming. Sharks also have multiple fins, such as pectoral and pelvic fins, for additional maneuverability.
Well it depends what shark it is.

How do sharks reproduce sexually or asexually?

Why some sharks are not edible?
Some sharks contain high levels of mercury and other toxins that can be harmful to humans if consumed. Additionally, some shark species are endangered and consuming them can contribute to their decline in population. It is important to be cautious when consuming shark meat to avoid potential health risks and to protect vulnerable shark species.
What are the main parts of a shark's respiratory system?
Quite simple. I have studied sharks for 5 years. Im only ten. They dont have lungs. They have to keep moving to force water through their gills. Other sharks like the White Tip Reef Shark can suck it in. So they force it through their gills and the gills extract the water molecules and let the oxygen molecules that have evaporated in the water flow down to the heart. The heart pumps them through a network of veins to the body cells The body cells turn the nutrients into energy. When the body cells do this the make a waste gas called carbon dioxide (c02) The heart can pump two ways so it pumps up the c02 back to the gills that extract them back into the water. It has to do that each breath.
Yes, sharks have predators such as larger sharks, killer whales, and some types of fish. Though sharks are apex predators in the ocean, they are not immune to being hunted or attacked by other marine creatures.
