We need to familiarize because this is very important in this topic . And also it gives a know about them.
Gross morphology refers to the study of the structure and form of organisms or organs that can be observed with the naked eye, without the need for microscopic examination. It involves examining the size, shape, and arrangement of tissues and organs in both plant and animal specimens. This field is crucial in various biological and medical disciplines, as it helps in understanding anatomical features and identifying abnormalities. Gross morphology can be assessed through dissections, imaging techniques, and physical examinations.
chondrichthyes and osteichthyes are the two classes of gnathostomata where fishes also lies
Fishes do not exactly float, except when they die. Although fishes can move upwards and downwards by rising and sinking, sort of like a helium filled balloon. To do this, fishes need to reduce its overall density by reducing its volume without increasing its mass. For this, fishes have what we call a 'swim bladder'. This an organ that expands and contracts, just like a human lung. When the bladder is inflated, the fish has a maximum volume and is pushed to the surface. When its deflated, it has a minimum volume and sinks. In this way, fishes are capable of rising and sinking and also staying at a particular level. Hope this helped :)
Oviparous fishes lay many eggs to increase the chances of offspring survival, as only a few may actually develop into adults. Viviparous fishes invest more energy in developing fewer offspring to ensure their survival by providing them with nutrients and protection during gestation. This leads to a higher likelihood of offspring reaching maturity compared to oviparous fishes.
fish need to be more streamlined than land mammals because they need to be able to stream quickly through water. They need to be able to do this for many reasons such as to either catch their prey (if they are large carniverous fish) or escape from their predator.
so that we will know where they come from
Familiarizing oneself with the morphology of fishes is essential for understanding their anatomy, physiology, and ecological roles. This knowledge aids in species identification, which is crucial for conservation efforts and fisheries management. Additionally, understanding fish morphology can enhance research in evolutionary biology and help address environmental changes impacting aquatic ecosystems. Overall, it provides valuable insights into biodiversity and the health of marine and freshwater environments.
The sentence you just used; as well as: "You really need to familiarize yourself about the horrors of SMART @$$es like me."
Try to familiarize yourself with your surroundings, they will always be changing.
A Life
Just so you can prove yourselves worthy.
Thats what i need to know :(
No
the fishes need filtering every week or 2 weeks

Fish need oxygen to live.
