Balıkların İngilizce Tanıtımı Kısa
Yunus Balıkları – Dolphins
Physical Characteristics
Bottlenose dolphins have two flippers and a tail. They are different than other dolphins because they have a pointy snout that makes them look like they are smiling. Dolphins have a blowhole at the top of their heads that they use to breathe. They have upper and lower jaws that have 20-26 pairs of small teeth. Dolphins have a dorsal fin which keeps them steady
while they are swimming and two tail flukes for moving up and down.
Male dolphins are called bulls and weigh between 300 and 500 pounds. Females, called cows are a little smaller. Newborns , called calves weigh about 25 pounds.
Bottlenose Dolphins have different colors on them. Their upper half is black, blue, or gray. Their sides are lighter and their bottom is light gray or pinkish white. Their colors are different so the dolphin can fool his predators. When they are seen, they don’t look like fish.
Balık : Fish.
A fish is any gill-bearing aquatic vertebrate (or craniate) animal that lacks limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related groups. Because the term is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification.
Most fish are “cold-blooded”, or ectothermic, allowing their body temperatures to vary as ambient temperatures change. Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., gulpers and anglerfish). At 32,000 species, fish exhibit greater species diversity than any other class of vertebrates.
Fish, especially as food, are an important resource worldwide. Commercial and subsistence fishers hunt fish in wild fisheries (see fishing) or farm them in ponds or in cages in the ocean (see aquaculture). They are also caught by recreational fishers, kept as pets, raised by fishkeepers, and exhibited in public aquaria. Fish have had a role in culture through the ages, serving as deities, religious symbols, and as the subjects of art, books and movies.
