» WILD ANIMALS OF THE OCEAN | Examples and features

In this article, we will talk about the wild animals of the ocean, those that live in total freedom and have not been able to be trained by man, and we will enter their mysterious world. It is estimated that 71% of our planet Earth is made up of both salt and freshwater. There are 5 oceans: Atlantic, Pacific, Indian, Arctic, and the Antarctic, so a large mass of water brings with it innumerable aquatic species.

The wild animals of the ocean, in addition to the known ones, can include mammals that spend their lives in the water but breathe outside it, such as dolphins, killer whales, and whales; these, although they obtain their oxygen in this way, cannot live outside the ocean. Also, other animals that can live entirely out of the water, but their anatomy is adapted to live in the same, such as beavers and seals. Some of the ones we can mention are:

10 Wild Animals of the Ocean

Shark

Its main characteristic is that its skin is thick and resistant. Its habitat will be where it finds food. They are animals with a very varied diet: fishmolluskscrabsoctopusesseals, and even other sharks.

Seals

These tender-looking animals are aquatic carnivorous mammals. Seals can live outside the water, but they can also adapt to spend most of their existence inside it. They have high speed and agility when swimming.

Whale Shark

The whale shark is the most massive shark that exists, as it measures about 12 meters long, looks very similar to a whale. Moreover, although its large size is imposing, its mode of feeding is the suction of small species.

Walrus

This enormous animal can weigh up to 2 tons because they are very corpulent animals. The primary deadly weapon of the walruses is the pair of tusks that protrude from their snout.

White Shark

Among the 10 wild animals of the ocean, we could not help but name the spectacular white shark. The older they are, the bigger they are. They are known as the great predator of the seas.

Lion Fish

It looks curious to the eye, but the lionfish hides a dangerous weapon between its fins: with them, it expels a poison, which can cause the death of small species.

Stone Fish

Another poisonous fish that stands out from the top 10 wild animals in the ocean is the stonefish. It has 13 spines on the back which, if pressure is applied, inject a quantity of venom. Their characteristic appearance allows them to camouflage very well.

Marine Crocodile

Also known as the saltwater crocodile. It can measure up to 7 meters in length and weigh 1 ton. When they grow, they feed on anything: fish, shellfish, sharks, and other species.

Sea Lion

It is a marine mammal of the pinniped family. They live in colonies with thousands of members. The sea lion has a high capacity to stay underwater without breathing for up to 40 minutes.

Giant Squid

The giant squid is a complicated animal to observe and find. It is estimated that one of these specimens can measure from 10 to 13 meters. Because they know so little about giant squid, they are said to feed on fish, shrimp and even another squid.

Characteristics of Ocean Wild Animals

How is the habitat for ocean animals

Wild animals in the ocean can adapt to different water pressures and salinity. Thanks to their adaptation to their habitat, they can also become accustomed to different water temperatures. Some have natural antifreeze or scales to protect them from this. Other ocean wildlife has a cartilage skeleton, which allows them to store fat. Also, others have a fat layer under the coat that protects them from low temperatures.

Nutrition

Their diet may vary according to their habitatthose living in the ocean have different modes of feeding. Carnivorous animals and hunters prefer to stalk their prey and ambush it using their teeth and tusks to tear it apart. Others are calmer and use sucking methods to get their food. Some use camouflage and wait for their prey to pass unawares.

Reproduction

Some use the viviparous form, which consists of giving birth to live offspring that developed into a placenta. The oviparous form is, however, the most common; after fertilization of the egg, a certain amount of eggs (depending on the species) are expelled into the water to complete their development there. So finally we have the ovoviviparous form, it is a combination of the two previously spoken; in this, the eggs are fertilized inside the mother’s uterus and grow there, and then they are hatched before or after childbirth.

However, asexual reproduction can also occur, i.e., without contact between the female and male. There are certain species of fish in which the offspring are clones of the female. Moreover, on the other hand, some animals leave their eggs and sperm in the water, and there occurs fertilization, interesting.

Breathing

We can find two ways in which these wild animals of the ocean breathe. Breathing through gills is based on absorbing the oxygen present in the water through the blood vessels present in them. On the other hand, other animals use the lungs, breathe oxygen out of the water and submerge; many species can last up to 40 minutes in the water, depending on their capacity.
