The animal handlers at the Oregon Zoo took Elephant around to meet some other animals. The sea lions were her favorite If you like this - please "like" our page. Oregon Zoo provided larger enclosures for their elephants. The Zoo made Zooliner, the first train in is still the primary train today.

Adorable: Chendra - Oregon Zoo's smallest Asian elephant - was delighted to meet Gus the sea lion during one of her morning strolls.

The genera Valenictus and Odobenus developed elongated tusks. Alternatively, this lineage may have spread from the North Pacific to the Arctic and subsequently the North Atlantic during the Pleistocene. Overall, they tend to be larger than other carnivorans; the southern elephant seal is the largest carnivoran. In lobodontine seals, females are slightly larger than males. Males of sexually dimorphic species also tend to have secondary sex characteristicssuch as the prominent proboscis of elephant seals, the inflatable red nasal membrane of hooded seals and the thick necks and manes of otariids.
Even some fully furred species particularly sea lions are less haired than most land mammals. The individual hairs on the coat, known collectively as lanugocan trap heat from sunlight and keep the pup warm. The pure white fur of harp seal pups conceals them in their Arctic environment.
All fully furred species molt ; phocids molt once a year, while otariids gradually molt all year. Pups are born with only a thin layer of blubber, but some species compensate for this with thick lanugos.
Most species have neither a cecum nor a clear demarcation between the small and large intestines ; the large intestine is comparatively short and only slightly wider than the latter. The length of the intestine may be an adaptation to frequent deep diving, as the increased volume of the digestive tract serves as an extended storage compartment for partially digested food during submersion.
Pinnipeds do not have an appendix. The former swims with its hind-flippers, the latter with its fore-flippers. Pinnipeds have two pairs of flippers on the front and back, the fore-flippers and hind-flippers. The elbows and ankles are enclosed within the body. Seals are more agile and flexible,  and some otariids, such as the California sea lion, are capable of bending their necks backwards far enough to reach their hind-flippers, allowing them to make dorsal turns.

In addition to their streamlined bodies, they have smooth networks of muscle bundles in their skin that may increase laminar flow and make it easier for them to slip through water. They also lack arrector piliso their fur can be streamlined as they swim. In addition, sea lions are known to "ride" waves, which probably helps them decrease their energy usage. Otariids and walruses are capable of turning their hind-flippers forward and under the body so they can "walk" on all fours.
Otariids rely on the movements of their heads and necks more than their hind-flippers during terrestrial locomotion. Sea lions have been recorded climbing up flights of stairs. Phocids are less agile on land. They cannot pull their hind-flippers forward, and move on land by lunging, bouncing and wiggling while their fore-flippers keep them balanced. Some species use their fore-flippers to pull themselves forward. Terrestrial locomotion is easier for phocids on ice, as they can sled along.

One exception is the walrus, whose smaller eyes are located on the sides of its head. The lens is mostly spherical, and much of the retina is equidistant from the lens center. The cornea has a flattened center where refraction is nearly equal in both water and air.
Pinnipeds also have very muscular and vascularized irises. The well-developed dilator muscle gives the animals a great range in pupil dilation. When contracted, the pupil is typically pear-shaped, although the bearded seal's is more diagonal. In species that live in shallow water, such as harbor seals and California sea lions, dilation varies little, while the deep-diving elephant seals have much greater variation.
This is reduced in bright light, as the retracted pupil reduces the lens and cornea's ability to bend light.Tiny Goat Visits Seals
They also have a well-developed tapetum luciduma reflecting layer that increases sensitivity by reflecting light back through the rods. This helps them see in low-light conditions. As such, they do not suffer snow blindness. This and its lack of orbital roof allow it to protrude its eyes and see in both frontal and dorsal directions.
As in many mammals and birds, pinnipeds possess nictitating membranes. In air, hearing is somewhat reduced in pinnipeds compared to many terrestrial mammals. While they are capable of hearing a wide range of frequencies e.
Their mystacial vibrissae have ten times the innervation of terrestrial mammals, allowing them to effectively detect vibrations in the water. Detecting vibrations is useful when the animals are foraging and may add to or even replace vision, particularly in darkness. The vibrissa's angle relative to the flow, not the shape, however, seems to be the most important factor.
These are important for detecting their prey on the muddy sea floor. Complete with high feeding stations simulating leaves in the trees and a pool deep enough for the elephants to fully submerge, I was amazed. I highly recommend timing your visit of the elephants with a feeding. We watched as Samudra, an 8 year-old male elephant, enjoyed apples and celery. Check out the video to see if Samudra caught the apple with his mouth!
Each elephant is trained in order to help the zookeepers with routine check ups and health care and we got to see some of it in action. Lifting feet, opening mouths, bending low…all are important to ensure the health of each Asian Elephant.
Truth be told, it was hard to leave the elephants. But we found ourselves at only the half-way point with so much more zoo to still explore. Each of the kids had a different favourite animal of the day.
For Kaia it was the bats. Why not a cute cuddly bear or cheetah? But bats it is. So while she sat on the ground and admired the upside-down mammals, I took some time to read about them.
In the end, I learned about the great service bats provide in keeping the fly population under control, so I conceded that bats are actually okay. Primate are also a big crowd pleaser. Chimpanzees, monkeys, orang-utans and more jump, swing and climb from tree to tree in their huge habitats. Their enclosures are large enough to really watch them enjoy a sunny day and play with one another.
My favourite of the day, though, came when we went indoors and one of the primates deliberately came over to say hello.
Never have I wanted to hug a monkey more than this guy. Some may think he just wanted to eat me, but I like to think we bonded for a moment and this is him coming in for a kiss. Titus wondered at the hippos. Koen mostly enjoyed holding my hand as we roamed the grounds and just liked everything that jumped around. And the big cats. He really liked the big cats. The Oregon Zoo is fantastic for a morning out or a full day.
Many locals have season passes and with so many animals to see, I understand why. There is always something amazing happening at the zoo.
