Do Pinnipeds Vocalize?

I wrote before about some differences about Seals and Sea Lions. There is one big difference between Seals and Sea Lions that I forgot to write about, which is that Sea Lions like to vocalize and Seals are generally quiet.

Sea Lions are extroverts.  They talk all of the time.  For example, when I was at the Bronx Zoo we could always here the California Sea Lions vocalizing. From what I have observed, Steller Sea Lions are not as talkative as California Sea Lions, but it does not take a long amount of time to hear them when you observe them in an aquarium.  If you want to hear what a California Sea Lion sounds like, click on this link to the Marine Mammal Center:  http://www.marinemammalcenter.org/education/marine-mammal-information/pinnipeds/california-sea-lion/#sounds

There is a time when Seals do vocalize a lot.  Mother Seals can recognize the individual cries of her little Pupper, and the little Pupper will reply.  As they call back and forth, the Mother is able to find her little Pupper.

Pinnipeds can vocalize under the water.  According to the book "Seals Of the World" by Judith E. King, the vocalization could be used as echolocation to locate food or avoid underwater obstacles.  You can hear various Pinniped underwater vocalizations at this link:  https://dosits.org/galleries/audio-gallery/marine-mammals/pinnipeds/

Walruses can make a surprisingly large number of sounds to include whistling, as you can hear in this YouTube video:



If you need to hear 10 hours of Walrus, go to this YouTube link:


And of course, no post on Pinniped vocalizations is complete without mentioning the infamous Egg:

Are Manatees Pinnipeds?

Image
     Many people think that manatees are a type of pinniped.  This sounds reasonable, since both are cute marine mammals shaped somewhat similarly.   Kali'na watches on while her mom eats lettuce, from website Zooborns However, manatees are actually in a group of animals called "sirenians" which include the West Indian Manatee, African Manatee, Amazonian Manatee, and the Dugong.  There are many differences between the sirenians and the pinnipeds. Relatives        One of the biggest differences between sirenians and pinnipeds are their relatives, as found in the fossil record.  Manatees are more closely related to elephants and hyraxes, and like those two animals are herbivores (they primarily eat plants).  They are from the clade "Afrotheria" comprised of animals of an African origin.  Pinnipeds, on the other hand, are their own clade and are closely related to Carnivores (primarily meat eaters), such as dogs and cats...

Pinniped Joy on Disney Junior: the Octonauts Get Their Pinniped Science Correct!

Image
The Octonauts is the most amazing marine life show ever!  Some may say it is for little kids, but I strongly disagree.  I think that the marine science is of such high quality that it is educational for people of all ages.  And fun and cute, too.  Right now, it is shown on Netflix.  It is a show where a group of ocean-loving animals "Explore! Rescue Protect!" marine life, with a strong science background. I always look forward to the Pinniped episodes.  For example, consider the quality science presented in Octonauts' Season 3 Episode 10 "Octonauts & the Harbor Seal." In this episode, Peso (the penguin Paramedic of the Octonauts) has to find "Nora the Remora" who had accidentally attached herself to a sailfish - don't ask, just accept. However, the Octonauts have no clues as to where Nora has gone. Captain Barnacles (the polar bear Captain of the Octonauts) knows that with so few clues there is only one animal too help. In a plot twist...

Chonk vs Cucumber: Measuring the Shape of a Seal

Image
While thinking about the rotundness of the chonky Baikal Seal, I wondered if there were any other "chonkier" Seals that looked rounder.  I wondered if I could actually calculate a ranking of seal "chonkness."  Because Seals come in different lengths, I had to compare the width of a Seal in comparison to their length.  For example, if a Seal has a 7 foot width but a 25 foot length, they will not be as "chonky" as a Seal with a 4 foot width and a 4 foot length, who would be a perfect sphere of rotund beauty and an absolute chonk. Since Seals with a longer length remind me of a cucumber, I called those who were more oblong than spherical ones with "High Cucumber."  Of course, those Seals who were more of little squished ovals becoming close to spheres of happiness are those with "High Chonk."  Please see my drawings below.  High Chonk:  Seal Approaching a Spherical Shape My drawing  High Cucumber:  Seal Approaching an ...
