Saltwater Fish

Feather stars and sea lilies are related but not the same. They both belong to the class Crinoidea, but feather stars can crawl and swim while sea lilies are sessile, anchored to the seafloor by a stalk.

caudal fin-the tail

pectoral fin-the tail on the ventral side of the shark just above the pelvic fins

pelvic fin- the underside fins that serve as the "arms" of the shark

dorsal fin-the top fin that is usually seen on the surface of water in shark attacks

Puffer fish are primarily carnivores, feeding on a diet of small invertebrates, algae, and plants. They are not herbivores as they do not solely consume plants, and they may also consume other marine animals.

The lionfish belongs in the nekton group. Nekton are aquatic organisms that are able to swim and move independently of water currents, unlike plankton which are drifters, and benthos which dwell at the bottom of a body of water.

Salmon are prey for a variety of animals, including larger fish like trout and pike, as well as mammals like otters, bears, and seals. Birds such as eagles and osprey also feed on salmon. Additionally, humans are significant predators of salmon for both subsistence and commercial fishing.

Tiger sharks are carnivores, with a diet consisting of a vast array of prey, including fish, seals, birds, crustaceans, squid, turtles, and dolphins.

The largest red fish species is the red drum (Sciaenops ocellatus), also known as redfish. The largest recorded red drum caught on rod and reel weighed 94 pounds.

Cyanobacteria, also known as blue-green algae, are a type of bacteria that can live in both fresh and saltwater environments and are capable of photosynthesis. They play a significant role in aquatic ecosystems by producing oxygen through photosynthesis.

Running water typically has more oxygen than standing water because the movement of the water helps to aerate and oxygenate the water. Freshwater usually contains more oxygen than saltwater due to differences in solubility and temperature affecting oxygen levels.

Blue Jays have broad, fanning wings that allow them to turn quickly in their forest habitat. However, they cannot fly swiftly in open spaces. Like other birds, the Blue Jay has very light bones that enable flight. The Blue Jay's wedge-shaped tail can be fanned open to allow quick stops and turns mid-flight.

Salt water will rust steel faster than fresh water or refrigerated water. This is due to the corrosive properties of salt, which accelerates the oxidation process that leads to rust formation on steel surfaces.

No, sharks are not herbivores. They are carnivorous predators that primarily feed on other fish, seals, and marine mammals.

Some insects that eat plankton include water boatmen, backswimmers, and certain species of beetles. They often feed on plankton in freshwater environments such as ponds, lakes, and streams. These insects play a crucial role in controlling plankton populations in aquatic ecosystems.

Fossils of ocean fish found in inland locations suggest that those areas were once covered by an ocean. This could be due to geological processes like plate tectonics or changes in sea levels over time, where the location of the ocean shifted.

A habitat provides an organism with food, shelter, and water.

Saltwater fish have special cells in their gills that actively pump out excess salt ions through a process called osmoregulation. This allows them to maintain a balance of salts inside their bodies despite living in a high salt environment. Additionally, they have efficient kidneys and excrete concentrated urine to further regulate their internal salt levels.

No, barracuda is not a decomposer. Barracudas are predatory fish that feed on other animals in the ocean, like smaller fish and crustaceans. They do not play a role in breaking down dead organic matter like decomposers do.

The world's fastest mammal, the cheetah, can reach speeds of up to 70 miles per hour, while the world's fastest fish, the sailfish, can swim at speeds of up to 68 miles per hour. Therefore, the cheetah is faster than the sailfish.

The price of sardines can vary depending on factors such as location, brand, method of preservation, and packaging. On average, a can of sardines can cost between $1 to $3. Fresh sardines may cost more per pound compared to canned sardines.

Bony fish use a process called buccal pumping to draw water into their mouths. By expanding their buccal cavity, they create a negative pressure which pulls water in. This helps them breathe by passing water over their gills for oxygen exchange.

Sea creatures breathe underwater using gills, which extract oxygen from the water. Gills are equipped with thin membranes that allow oxygen to pass through and carbon dioxide to be released. This process enables sea creatures to extract oxygen from the water in order to survive.

Clownfish are not particularlily 'helpful' to their environment. Very few species, in fact only one (Homo sapiens - mankind) strive to help their environment. Clownfish live in the reef environment, and as a by product of their behaviors and breeding, they provide food (baby clownfish) for the reef, and also produce metabolic waste that helps aglae to grow.

The pelage in rats serves as insulation, helping to regulate their body temperature. It also provides protection from external elements and predators. Additionally, the coloration and patterns of the pelage can be important for camouflage and communication within their social groups.

the aphotic zone.... but where in the aphotic zone???
At depths of 3000 meters, where no sunlight can penetrate. It survives thanks to its bioluminiscent crest on its head and by its stomach that it can make three times bigger than itself.

Mudskippers are carnivores. They eat small crabs, worms and insects.
