May 7, 2021 · There are two main groups when it comes to seals and how they swim. Seals that live predominantly in the northern hemisphere, such as grey and harbour seals, are from a group known as the true seals, or phocids. These have stubby, clawed paws which they can use to manipulate food and propel themselves through the water using their feet.
Nov 24, 2023 · Adapted Respiratory System. Many seal species are able to dive thousands of feet below the water’s surface in search of food, but this means that they need to be able to hold their breath for a long time. In some cases, seals can remain under the water for up to an hour, and this is thanks to their highly specialized respiratory systems.

Seals are aquatic mammals, but they are more closely related to bears and skunks than any other marine mammals. That could be because they were once exclusively terrestrial, living entirely on dry land, but more about that later. Unlike other marine mammals, seals spend long periods on land using nearby oceans and lakes for foraging and hunting. Mo...
Seals are scientifically known as pinnipeds, which means fin-footed, and all seals have fin-shaped feet, or feet-shaped fins, depending on your perspective. This is one of just a couple of characteristics that all seals share, with the other being a fusiform or torped0-shaped body that tapers at both ends.
Whenever I think of seals, my mind automatically conjures up images of cute, furry Harp seal pups with their thick white coats and big, black eyes. Not all seals look like that; in fact, even adult Harp seals bear little resemblance to their pups. It’s difficult to see the similarities between an 8,800-pound walrus and a 20-pound seal pup, but ther...
There are so many different species of seals living in a diverse range of ocean and freshwater habitats that it’s difficult for anyone to accurately estimate the current world population. However, one thing’s for sure – while some populations are thriving, others are decreasing rapidly due to a variety of threats. According to the International Uni...
The 32 species of seals are divided into three species, with the first being the true seals. True seals appeared to have no ears, so also called earless seals. They do have ears; they just don’t have external ear flaps. Instead, the entire organ is hidden under their skin. That’s only one of many secrets we will reveal in this article! Species of e...
I struggled to track the exact origins of the word ‘seal,’ although some sources suggest that it could have come from an old European word meaning “to pull” or plow. Although that makes some sense, as seals do plow their way through the water, it’s by no means as descriptive as the Dutch word. They call it the “zeehond,” which means sea hound, and ...
Seals are mammals and, as such, belong to the Mammalian class along with over 6,000 other species. Within the class Mammalia, there are 26 different orders, of which seals fall into the order Carnivora, which also includes wolves, bears, hyenas, and dogs. Seals have their own sub-order, pinnipeds, but are divided into different families based on th...
In the dim and distant past, seals lived on the land just like most other members of the Carnivora order. When scientists discovered an Arctic fossil dating back some 20 million years, the evolution of the seal became much clearer. The Puijila darwini was an otter-like creature that lived on land but had webbed feet that enabled it to swim well eno...
Regardless of whether they’re Harbor seals or Ringed seals, all seals are shaped a little like bowling pins, with small heads and large, rounded bodies that taper towards their hind flippers. As they evolved into marine mammals, they adapted to their new environment, developing ingenious ways to regulate their body temperatures while developing acu...
Seals live in coastal waters all over the world, with different species inhabiting different climates and habitats. Northern fur seals and Monk seals are the most common species in the North Pacific, while the Southern Ocean is dominated by the highly specialized Crabeater seal. Up in the Arctic Ocean, you can expect to encounter any one of the six...
- They have been around for a long time. Fossil records indicate that the ancestors of modern seals first entered the ocean on the west coast, about 28–30 million years ago.
- There are three different major types of pinnipeds. “Phocid seals” are also called “true seals” and include several species such as harbor seals and gray seals.
- They have whiskers they use like cats do. Seals and sea lions have many well-developed whiskers, much like cats. Like cats, they have a very acute sense of touch.
- They can go for long periods of time without eating. A seal’s body stores enough fat in the blubber layer to allow the animal to go for extended periods of time without eating.
Jun 22, 2018 · Accordingly, Kanatous et al. (1999) found that short-duration divers, such as the harbour seal, have a well-developed capacity for aerobic metabolism, particularly in the typical swimming muscles. Even so, such seals still have a smaller capillary-to-fibre interface and capillary supply per fibre mitochondrial volume than dogs (Kanatous et al ...

Nov 20, 2022 · Swimming is not uncommon for seals, but they can also stay under water for extended periods of time. Furthermore, these seals can dive to depths of up to 100 meters. Special Adaptations Seals. Seals have adapted well to cold polar environments due to their thick blubber layers that serve as both insulation and food reserves.
