While fish near the surface may die when lightning strikes the water, the fish that are deep underwater are likely to survive. Lightning strikes the surface of the water, but its electricity is neutralized deeper down.
A:Fish have adapted to their environment through the evolution of gills, swim bladders and fins. Gills allow fish to absorb oxygen from the water, swim bladders allow fish to maintain an appropriate level of buoyancy and fins allow the fish to move through the water. Different species exhibit specializations of these features to thrive in their own way.
A:African dwarf frogs, snails and ghost shrimp, due to their unique characteristics, are all compatible tank mates for the betta. Other fish may be compatible depending upon the temperament of the individual betta. In general, avoid colorful fish, fish that are fin nippers, fish that live in brackish water, and fish that grow too large and overwhelm the tank space.
A:Sea fish feed on small creatures, smaller fish and various dead organisms that drop down from higher water levels. It is common for sea fish to go as long as two weeks without eating, as food is often scarce in the deep sea.
A:The heaviest flounder ever caught was 22 pounds, 7 ounces, landed in Montauk, N.Y., on Sept 15, 1975, by Charles Nappi. The species was a summer flounder, Platichthys flesus. This type of flounder ranges from South Carolina to Maine in the western Atlantic.
A:The most common theories as to why mullets jump out of the water are because the mullets are attempting to shake away parasites, break open eggs during spawning season or avoid predators. Mullets, also called gray mullets, are part of the Mugilidae family and are ray-finned fish found throughout the world in tropical and coastal waters.
A:Salmon do have scales, and the scales have concentric rings that can be counted to determine the age of the fish. Salmon scales and skin do not have to be removed before cooking, which makes preparation easy.
A:Goliath grouper are the largest members of the sea bass family in the Atlantic ocean. They weigh up to 800 pounds and are up to 8.2 feet in length. They are also heavily built, and their bodies are half as wide as they are long at their widest point.
A:A fish has a heart, which acts as the center of its circulatory system, pumping blood throughout the body and transporting vital nutrients and oxygen to cells. The size, placement and strength of a fish's heart differs between species.
A:Salmon return to rivers from the ocean and swim upstream to their original hatching place to lay and fertilize their eggs. Swimming upstream is hard work, and only the strongest complete the journey and spawn the next generation of salmon.
A:Types of goldfish that have oversized eyes include bubble eyes, celestials, telescopes and black moors. A fifth type of large-eyed goldfish is the demekin, which is a cross between the telescope variety and the arch-bodied ryukin variety.
A:The fuzzy dwarf lionfish is a species of the Scorpaenidae family native to the waters of Africa and Indonesia. A popular aquarium fish, it bears red, white and black vertical stripes and is named for the fullness of its tall, quill-like dorsal fins and fan-like pectoral fins.
A:According to National Geographic, puffer fish live in sub-tropical and tropical waters. In Asia, they are commonly found around Japan, China, Taiwan and the Philippines, while in the Caribbean, they are found in the West Indies and Mexico.
A:The wild Atlantic salmon is a fish of the Salmonidae family, native to the northern Atlantic Ocean and rivers flowing into it. The juvenile salmon live in freshwater rivers and streams until they migrate out to sea, eventually returning to spawn.
A:While fish near the surface may die when lightning strikes the water, the fish that are deep underwater are likely to survive. Lightning strikes the surface of the water, but its electricity is neutralized deeper down.
A:Baby fish are initially called larvae, then fry and finally fingerlings before they mature into adult fish. Larvae are totally dependent on their yolk sac, while fry are able to feed themselves. Fingerlings have functional fins and scales that are comparable to adult fish anatomy, unlike fry.
