Dorsal fin

means those sound waves bounce off of the walls and echo back, creating...an "acoustical hell" for the animals” (Rooney, 1). The lack of ocean current and deep depths can also create a collapsed dorsal fin-- a rare condition for wild Orcas. Although, almost all of captive Orcas display collapsed dorsal fins. Due to inadequacy space and surroundings Orcas should be released into the wild or an ocean…

one that has ever lived in the wild was 80 years old according to National Geographical. Beluga whales range from 10-17 feet long and can weigh from 2,000 to 3,500 pounds. Males exceed over 18 feet long and reach 3,500 pounds. Beluga whales lack a dorsal fin in return it gives them the ability to swim backwards. Characteristics of a beluga whale include the following: belugas are stout in small in size, they have a blunt head that gives the distinctive whale look, they have a small beak used to…

Their extended bodies are surrounded by bony rings with small gill slits (Zubi, 2004). Their fin patterns and distributions are different than those for other bony fish. They have no pelvic fins, small pectoral fins, and one dorsal fin (Zubi, 2004). The pectoral fins turn the Seahorse and aid in steering, while the dorsal fin moves it forward. The coronet of the Seahorse is its most distinctive feature, helping in identification as the thumbprint does for humans (Zubi, 2004). Seahorses are…

Animals used in circuses spend most of their lives chained inside boxcars and never get to live without restrictions. In zoos, animals often live in enclosures or cages that are many times smaller than their homes in the wild. In marine parks like SeaWorld, orcas are given what is, all in all, a concrete bathtub to live in. Elephants are clever, considerate, and affectionate animals. They have the largest brains of any land animal. They care about each other and can become depressed when they…

An area of coastal wetland that is regularly flooded and drained by seawater is known as a salt marsh. Salt marshes are extremely important to many species as it serves as their habitat, and also saves them from potential predators as only certain species are able to live in the environment of a salt marsh. The salt marsh is mostly shallow and brackish, and consists of mostly saltwater. Salt marshes often develop amid marine and terrestrial environments, which results in biologically diverse…

tons. The diet of the blue whale consisits of mostly small crustaceans known as krill but also eat small plants and fish. The blue whale’s body type is long and slender and their body shade varies from greyish blue to a dark navy blue. The whales dorsal can have a light shade underneath. There are at least three distinct subspecies: The first being, musculus of the North Atlantic and North Pacific, the second being, intermedia of the Southern Ocean and the third being the brevicauda (also…

My shape is look like my relatives- other type of porpoise, but I’m the only one without a true dorsal fin.

My diet is depend on where I’m living, let me tell you a secret, I will eat leaves, rice and eggs too…

Introduction: Currently there are 50 orcas living in captivity around the world. Majority of them are living in marine lands and amusement parks in tanks that are not even close to their natural environment. The confined quarters and limited interaction with other members of the species fail to replicate an orca’s natural existence. This can lead to aggression which causes the orcas to attack their trainers or even other orcas. Orcas living in captivity have to perform in front of people for…

pectoral and pelvic fins with the pectoral longer than the pelvic ones. Their soft cycloid scales are embedded in the skin. African lungfishes are characterized by their prominent snouts and small eyes. African lungfish use their small gills that are retained in two anterior gill arches for respiration. They reach a length of about 1 m in the wild with the largest recorded specimen of 2-m long. The shape of their bodies allows them to swim like eels, while the shape of their fins (pectoral and…
