Fish Habitats and Adaptation
Fish are known to inhabit varying aquatic habitats from pools formed by large rivers to the main rivers, streams, lakes, ponds and the oceans. There are distinct characteristics that the fish have that allow them to live adequately within the habitants that they are in. The various adaptations that fish have formed over the years as they evolve allow them to have temperature tolerance, ability to breath, tolerance to salt and also movement to search for food as well as a defense mechanism.
The focus of this paper will be on the fresh water fish as is seen on the diagram and will highlight the most outstanding adaptations that evolution has endowed them with for their survival. One common aspect is the camouflage that fish has which makes then blend against the background to avoid predators and any potential harm...
The other adaptation is the streamline shape of the body which gives them the ability to swim freely and easily through the water to find food and also escape from potential danger or hunter. The streamline bodies enable the fresh water fish to dart at insects at the surface of the water for food. The caudal fin is also an adaptation that enables them to gather higher speeds while swimming as it gives the fish the forward thrust that it needs. The pectoral and the pelvic fins are also an adaptation that fish have acquired over the years and these two enable them to glide through water for hundreds of yards without thrusting hence cutting down on the energy demand from the body. A large mouth size is also an adaptation for these fresh…

The female wolverine delays implantation; the egg cells float in the uterus for some time attaching to the uterus wall. Delayed implantation means that the young can be born at the right time, from January to April, regardless of when mating takes place. The female produces one litter every two or three years. She digs out a den in a snowdrift, in a tree hollow, or under a rock,
Fishes to Frogs: Respiratory Adaptation Respiration Evolution: Fishes to Frogs The energy needed to sustain life depends on the reduction of oxygen during glycolysis, thereby producing ATP, water, and carbon dioxide. As multicellular organisms began to evolve and grow in size, the ability of the inner-most cells to receive enough oxygen to carry out cellular respiration was compromised. The absorption of oxygen through the outer cellular layers, called cutaneous respiration, evolved
This provided the context for an extreme diversification of fish across the world. Within the evolution of the jaw, there are general patterns of predatory and defense mechanisms, as well as the construct of the armor of modern fish. With the evolution of jaws in fish, there was much less of a need for body armor for protection. Rather, the fish stepped out of the prey position and into a
Physiological Evolution of Fish The anatomy of a typical fish adapted from Moyle, P.B., & Cech, J.J. (1982). How fish has evolved physiologically to become suited to its environment Fishes have been around for utmost 500 million years during which time they have managed to adapt to any type of aquatic habitat. Physiologic features the fish posses that make them more adapted to the environment they live in are not universal to all
Evolution and Adaptation of the Owl Over the years studies have endured to study the owl in its natural environment and in the controlled environment. Much has been found about owls but more can still be learnt. Owls are said to belong to the Aves as their phylogenetic and two distinct families of owls have been pointed out, the Barn owls and the other types of owl. There are 17 known
