What fish has poison spikes?

The Scorpion or Dragon fish in tropical waters, many species, deadly &

Similarities between respiratory system of insects and fish?

Both respiratory systems rely on diffusion to exchange gases. In insects, air enters through spiracles and travels through a network of tracheal tubes, while in fish, water is taken in through the mouth and passed over gills where gas exchange occurs. Both systems are efficient at extracting oxygen from the surrounding environment to support metabolic functions.

What mammals are fish?

No mammals are fish. Mammals and fish are distinct groups of animals with different characteristics. Mammals are warm-blooded vertebrates that have hair or fur, while fish are cold-blooded aquatic vertebrates that have scales and gills for breathing underwater.

Which group of fishes are most closely related to the ancestral amphibians?

The group of fishes most closely related to ancestral amphibians are the lobe-finned fishes, which include the coelacanths and lungfishes. These fishes share certain characteristics with amphibians, such as limbs with digits and lungs or lung-like structures, indicating a close evolutionary relationship.

What is the respiratory medium of people and fish?

Humans primarily use air as their respiratory medium, extracting oxygen from the air and releasing carbon dioxide. Fish, on the other hand, use water as their respiratory medium, extracting oxygen from the water through their gills.

Where in Alabama were dinosaur fossils found?

They uncovered it while were searching on a recent road cut in southeastern Montgomery County. The specimen found is believed to be a juvenile. The dinosaur measured in life about 19 ft in length.

How did fish evolve?

Fish were the first chordates (organisms with a spinal cord), and also the first vertebrates (organisms with a spinal column). Developing a spinal cord gave them an advantage over their arthropod enemies, because they could swim faster and were much more agile.

It is difficult to say exactly when the first fish evolved or which was the first fish, but we do know that the earliest fish evolved between 400-500 million years ago. They were jawless, with gills and scales but no fins. Eventually fish greatly diversified and occupied almost every water environment. They developed fins and a strong tail to help them swim better. They were also the first animals to develop jaws and teeth, enabling them to eat other animals.

The following lists the possible evolution of the fish over time:

About 460 to 480 million years ago: The first jawless fish evolve. (It's worth noting here that this starting point is hotly debated in the scientific community.)

About 450 million years ago: The first jawed fish emerges.

About 390 million years ago: The ancestors of the bony fish evolve.

About 380 million years ago: The first shark-like fish evolves.

About 360 million years ago: The early offshoots of the bony fish (Osteichthyes) evolve into the first amphibians (intermediates between fish and reptiles).

About 175 million years ago: The first true bony fish emerge.

Between 190 and 135 million years ago: The first modern sharks evolve.

Carnivore fish lives in amazon?

One example of a carnivorous fish found in the Amazon is the piranha. These sharp-toothed fish are known for their scavenging and hunting habits, often feeding on smaller fish, insects, and even larger prey when in a group. Their aggressive feeding behavior has earned them a fearsome reputation.
