Aquatic Mammals

The largest Antarctic marine mammal is the southern elephant seal (Mirounga leonina). This species of seal can weigh over 8,800 pounds and reach lengths of up to 20 feet. They are known for their large size and loud vocalizations during the breeding season.

Aquatic organisms respirate by extracting oxygen dissolved in water through their gills or body surface. The oxygen is then delivered to their cells, where it participates in cellular respiration to produce energy. Carbon dioxide, a byproduct of respiration, is released into the surrounding water.

It is a sensory organ at the tip of their lower jaw with no name yet. Whales use a technique called "lunge feeding" where they suck in tons of water and then filter their food out from the water with their baleen. The sensory organ helps them detect their prey and coordinate the critical timing of the opening and closing of their vast mouths to keep it from escaping.

High levels of DDT found in grebes can be due to bioaccumulation, where the pesticide builds up in the food chain reaching toxic levels in top predators like grebes. Grebes consume contaminated fish and aquatic insects which leads to a high concentration of DDT in their bodies. Efforts to decrease the use of DDT and monitor its presence in the environment are important to protect wildlife like grebes.

A marine mammal is an animal that lives in the ocean and breathes air, like whales, dolphins, seals, and manatees. These animals have adapted to life in the water and often have special characteristics to help them survive in the marine environment.

A water habitat refers to an environment where organisms live in or around water, such as lakes, rivers, ponds, and oceans. These habitats provide essential resources like food, shelter, and breeding grounds for aquatic organisms such as fish, amphibians, and various water-dwelling plants and invertebrates. Protecting water habitats is crucial for maintaining biodiversity and ecosystem balance.

Some species of whales engage in a form of mutualism with fish. For example, certain types of whales may work together with fish to capture prey by herding them into a concentrated group for easier feeding. This behavior benefits both the whales and the fish involved.

Yes they do. For example, when a female humpback whale reach her breeding grounds, she will announce her arrival by turning onto her back, and slapping the water with her huge flippers. Several males will soon come on the scene, the female will then swim away, with her suitors giving chase for hours. Each male will compete with each other, to be by the females side. These chases can get very aggressive, and humpbacks have been known to be killed fighting for the females acceptance, and the right to mate. Constantly banging into each other, using deep bellowing sounds, and masses of bubbles to intimidate, they breach out of the water, trying to submerge their rivals; Until finally the victor breaks free to be by the females side, and everything goes calm once more.

The female actively encourages this behavior, to ensure that she has secured the strongest male to breed with. Only then, will the male and the female descend into the depths, where mating will take place.

Sea creatures are classified as organisms that live in marine environments, including fish, mammals like dolphins and whales, invertebrates such as jellyfish and squids, and other aquatic organisms like sea turtles and seahorses. They play important roles in marine ecosystems and come in a wide variety of shapes, sizes, and habitats.

Dolphins rely on their speed and agility to evade predators. They may also use their ability to dive deep underwater or swim in a group to confuse predators. Additionally, dolphins have a keen sense of hearing and echolocation, helping them detect threats in their environment.

A hard-shelled sea creature that starts with the prefix "bar" is a barnacle. Barnacles are small marine crustaceans that attach themselves to hard surfaces, such as rocks or the hulls of ships, using a strong, adhesive cement.

It is highly unlikely for a saltwater crocodile to kill an Orca, as Orca whales are much larger and more powerful predators. Crocodiles are typically ambush predators that target smaller prey in the water, whereas Orcas are apex predators that have been known to hunt and kill crocodiles in their habitat.

A female whale is called a cow, and the male is called a bull.

well its not because there is no fish that eats plants

It is estimated that around 100,000 marine animals die each year as a result of plastic bag pollution. This includes animals such as sea turtles, whales, and seabirds who mistake plastic bags for food or become entangled in them.

Whales produce sound through structures in their bodies called "phonic lips," which vibrate and emit sounds. These sounds can range from low-frequency rumblings to high-frequency clicks and whistles, depending on the species. Whales use vocalizations for communication, navigation, and locating prey in their underwater environments.

No, whales do not have two brains. They have a single brain like other mammals, but it is highly complex and adapted for their aquatic lifestyle. The belief that whales have two brains may be a misunderstanding of their large brain size and unique neurological adaptations.

The largest member of the order Carnivora is the polar bear (Ursus maritimus), which can weigh up to 1,500 pounds and reach lengths of over 10 feet.

A whale's tail, also known as a fluke, can vary in size depending on the species. On average, a whale's fluke can be between 10 to 12 feet wide.

Walruses do not hibernate, but they do migrate with the changing seasons. They travel long distances in search of food and suitable breeding grounds. In the winter, they often migrate to warmer waters with more abundant food sources.

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.

They are mermaids....... they live under water.

Sponges are basket-shaped creatures that live in colonies attached to surfaces underwater. They are filter feeders that rely on water flow to bring them food.
