Suborder Mysticeti (baleen whales) includes the great whales (the largest whales) such as the blue whale, the finback whale, humpback whale, and the gray whale. The baleen whales have no teeth. Instead they have baleen, plates of fibrous material that hang from the whale’s upper jaw on the inside of their mouths.
What does a dolphin melon do?
That giant forehead on the dolphin is called a melon. And it acts like an acoustic lens, aiding in sound recognition. In addition to the melon, the dolphin’s teeth are arranged in a way that they function like antenna, receiving incoming sound.
What does a dolphin’s melon do group of answer choices?
What does a dolphin’s melon do? The melon focuses sound waves during emission.
What do whale lice eat?
algae
The lice predominantly eat algae that settle on the host’s body. They usually feed off the flaking skin of the host and frequent wounds or open areas. They cause minor skin damage, but this does not lead to significant illness. The development of the whale louse is closely connected with the life pattern of whales.
What is the role of the spermaceti in the sperm whale?
The most likely primary function of the spermaceti organ is to add internal echo or resonator clicks to the sonar echolocation clicks emitted by the respiratory organs. This makes it possible for the whale to sense the motion of its prey as well as its position.
What animal did the whale evolve from?
The descendants of Dorudon went on to evolve into modern whales. About 34 million years ago, a group of whales began to develop a new way of eating. They had flatter skulls and feeding filters in their mouths. These are called baleen whales, which include blue whales and humpback whales.
What part of a fish helps it sense vibrations in the water quizlet?
The lateral line is a system of sense organs found in aquatic vertebrates, mainly fish, used to detect movement and vibration in the surrounding water.
What does the lobster shown in this video use for defense?
What does the lobster shown in this video use for defense? It uses its spines all over its hard shell, including the spines on its antennae. Why is it rare to find a lobster in a tidepool? Because they normally live along the bottom, further offshore in kelp forests.
Is overfishing really a problem quizlet?
Is overfishing really a problem? Yes. Over 80% of fish and 90% of top predators are currently being harvested at rates that are unsustainable.
Which whale has teeth instead of baleen quizlet?
Suborder Odontoceti (toothed whales) have prominent teeth and includes killer whales, sperm whales, porpoises, and dolphins. Suborder Mysticeti (baleen whales) includes the great whales (the largest whales) such as the blue whale, the finback whale, humpback whale, and the gray whale. The baleen whales have no teeth.
Why do tuna need more myoglobin than other fish such as grouper?
Why do tuna need more myoglobin than other fish, such as grouper? It allows them to swim faster for a longer period of time.
What is baleen made of?
Strong but flexible, baleen is made of the same substance as your fingernails – keratin.
What is the purpose of the melon?
The melon is a mass of adipose tissue found in the forehead of all toothed whales. It focuses and modulates the animal’s vocalizations and acts as a sound lens. It is thus a key organ involved in communication and echolocation.
How does the melon work?
The melon is filled with fatty tissue and fluid and acts like an acoustic lens to focus the sounds in different directions. The sound waves then bounce off of objects of interest and are received by the dolphin’s lower jaw as an echo. This information is then passed to the brain via the inner ear.
How do dolphins produce sound?
Dolphins make sounds in air by releasing air through their blowholes. The dolphins have great muscle control over their blowholes and can alter the sounds by changing the size and shape of the blowhole opening.
What is the function of the melon in Odontocetes?
The melon is a lipid-rich structure located in the forehead of odontocetes that functions to propagate echolocation sounds into the surrounding aquatic environment. To date, the melon’s ability to guide and impedance match biosonar sounds to seawater has been attributed to its unique fatty acid composition.
What does a melon do in an orca?
Orcas also use echolocation. They create high frequency sound waves that are passed through the melon. The melon focuses these sounds and projects them into the water. The sound bounces off the objects and returns in the form of an echo.
