Several aquatic animals have appendages, such as flippers, that are used as a source of locomotion. Depending on the type of animal, flippers come in different sizes and are usually associated with the same type of bone joints.
Several aquatic animals have appendages, such as limbs, that support their body while they spend time on ground. They are usually small because they spend most of their time in the water.
The ball and socket joint of an aquatic animal allows the bones connected to it to move in all sorts of directions. It is usually associated with the shoulder or hip area and connect to appendages such as flippers, limbs, or tails.
The main purpose of an aquatic animal's ribcage is to protect its inner organs, such as the heart, from damage or injury. The ribcage is connected to the backbone of the animal and is made of mostly bone.
Aquatic animals use their skull to protect their brain from damage and injury. The skull may contain paired eyes and nostrils that aid the animal in capturing prey or avoiding its predators.
This course details the quantitative treatment of chemical processes in aquatic systems such as lakes, oceans, rivers, estuaries, groundwaters, and wastewaters. It includes a brief review of chemical thermodynamics that is followed by discussion of acid-base, precipitation-dissolution, coordination, and reduction-oxidation reactions. Emphasis is on equilibrium calculations as a tool for understanding the variables that govern the chemical composition of aquatic systems and the fate of inorganic pollutants.
Seahorses and seadragons both live in oceans. They also both come in different shapes and sizes. They both have hard, rigid bodies and move very slowly. Both seahorses and seadragons reproduce with the males carrying the eggs instead of the females. Both can change colors to match their environment. Seahorses can grab onto plants while seadragons cannot.
Goldfish love to eat small aquatic plants. Some common plants that they eat are called duckweed and elodea. People that own goldfish can feed them processed fish flakes instead.
Goldfish have fins to swim with, a tail to steer and swim with, and gills to breathe with. They also have scales for protection. Goldfish live in water.
Goldfish live in the water. They use their gills to breathe. Goldfish swim in water to move around. This goldfish has pectoral fins, pelvic fins, anal fins, and dorsal fins that it uses to swim. The tail is used to steer the goldfish wherever it is going.
