Aquatic Mammals

No, purpoises do not spout like whales. While both are marine mammals, purpoises lack the prominent blowholes that whales use to forcefully expel air and water vapor, creating a spout. Instead, purpoises exhale and inhale through their blowholes more quietly and without a visible spout. Their breathing is generally less dramatic compared to that of larger whales.

Narwhals typically travel about 1,500 miles north to reach their spring migration spots in the Arctic, specifically to areas in the Canadian Arctic and Greenland. This migration is driven by the search for food and the need to find open water as sea ice melts. The journey can vary based on environmental conditions and the individual pod's habits.

Well honey, a whale's throat can be pretty darn big, ranging from the size of a grapefruit to as wide as a car. So, to put it simply, it's big enough to swallow you whole if it wanted to. Just be glad they prefer krill over humans.

Seals have several defense mechanisms to protect themselves from predators. One common defense mechanism is their speed and agility in the water, allowing them to escape from potential threats. Seals also have sharp teeth and strong jaws that they can use to defend themselves if necessary. Additionally, seals can blend into their surroundings by changing their coloration to avoid detection by predators.

The concept of sea animals dreaming is not well understood in scientific terms, as dreaming is typically associated with complex brain activity during REM sleep, which is not well-documented in sea creatures. While some marine mammals like dolphins and whales exhibit behaviors similar to sleep, it is unclear if they experience dreams. Therefore, there is no specific term for a sea animal's dream in scientific literature.

If a whale ingests a balloon, it can cause harm to their digestive system and potentially block their intestines, leading to serious health issues or even death. It is important to properly dispose of balloons to prevent marine animals from accidentally consuming them.

A baby dolphin weigh about 300 pounds

Leopard seals typically have around 34 teeth in total, with 12 teeth in the upper jaw and 22 teeth in the lower jaw. These teeth are sharp and interlocking, ideal for catching and eating prey like fish, squid, and other seals.

Second to the top - they are predators but I believe that a Killer Whales probably kill and eat them so they are not the top predator.

So the pyramid would go (starting at the bottom):

Plankton -> fish-> penguin -> Leopard seal -> Killer Whale

• An autotroph (self + feeding) is an organism that makes it own food using light energy or chemosynthesis. Examples are plants and algae.
• A heterotroph (different + feeding) uses organic (living) carbon for growth. Examples are animals, fungi and bacteria.
• A fish is an animal and does not make its own food, so it is a heterotroph.

Baleen is a filter-feeding system made of keratin found in certain whale species, particularly in the mouths of baleen whales. It is used to filter and trap small prey, such as krill, while allowing water to pass through.

On the outside, the fins of a whale resemble the fins of a fish, because they have evolved for the same purpose. But when you look at a whale skeleton, the fins look like arms and hands. That's because whales are not fish, they are actually mammals that have evolved from land-dwelling creatures with four legs.

A whale's tongue does not weigh 4 tons. The tongue of a whale is lighter, typically weighing around a few hundred pounds. The large size of a whale's tongue is advantageous for filter-feeding and consuming large amounts of food.

Yes, limestone is a sedimentary rock primarily made up of calcite and aragonite minerals, which are derived from the shells of marine organisms. Over time, these shells accumulate and are compacted to form limestone rock.

Whales swim in packs, or pods, for social reasons such as cooperation in hunting, communication, and raising offspring. Swimming in groups helps them to find food more efficiently, protect each other from predators, and navigate the vast ocean.

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.

Unfortunately, you can't from the BBC because it doesn't sell market, but there might be a Nev the bear soft toy coming out for a charitiy event soon!

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.
