1. BLUE RINGED OCTOPUS is an Animal that Starts with O

The blue-ringed octopus is an extremely venomous animal known for the bright, iridescent blue rings it displays when threatened. The small octopuses are common in tropical and subtropical coral reefs and tide pools of the Pacific and Indian Oceans, ranging from southern Japan to Australia. Although deadly, the animal is docile and unlikely to bite unless handled. Ordinarily, a blue-ringed octopus is tan-colored and blends in with its surroundings. The iridescent blue rings only appear when the animal is disturbed or threatened. The blue-ringed octopus hunts small crabs and shrimp during the day.

2. OSTRICH is an Animal that Starts with O

Found across Africa’s hot savannahs and open woodland, the ostrich is the world’s largest bird. This flightless bird has a long, bare neck, long, sturdy legs and a bulky body covered with feathers. Males and females have different coloured feathers – males sport black plumage with a white tail, and females are mostly brown. The ostrich might not be able to fly, but boy can it run! Using its long legs, it can reach up to 45 mph. Ostriches are mainly vegetarian, eating roots, leaves, flowers and seeds. But they will also eat insects, lizards and other small creatures, too.

3. OKAPI is an Animal that Starts with O

Known as the “forest giraffe,” the okapi looks more like a cross between a deer and a zebra. It can blend into its surroundings thanks to the brown and white stripes on its rump, which mimic the appearance of streaks of sunlight coming through the trees. Its plant-based diet consists of fruits, buds, leaves, twigs, and other vegetation. Just like the giraffe and cow, the okapi has four stomachs that aid with digesting tough plants. Also like its giraffe cousin, the okapi has a long, dark tongue that can strip leaves from branches.

San Diego Zoo researchers discovered that okapis have a secret language. They watched okapis closely and recorded their sounds. The researchers heard coughs, bleats, and whistles quite often, but it wasn’t until they returned to the Sensory Ecology Lab to examine their recordings closely that they realized okapis also use other calls with very low frequencies. These calls are so low, in fact, that we humans cannot hear them at all! Check out this super cute video of one of their baby Okapis!

4. OPOSSUM is an Animal that Starts with O

The only marsupial in North America, is the Opossum! They are often considered to be a pest, but play a vital role by eating ticks! Opossums are immune to rabies. They have a body temperature too low for rabies to survive. While most animals look at a snake and see danger, a opossum sees its next meal. The animals are immune to the venom of nearly every type of snake found in their native range, the one exception being the coral snake. Oossums take advantage of this adaptation by chowing down on snakes on a regular basis. Perhaps the most famous characteristic of the opossum is its tendency to play dead in front of predators. When the animal experiences intense fear in the face of danger, it seizes up and flops to the ground where it can remain for hours staring blankly ahead and sticking out its tongue. It’s an impressive defensive mechanism, but its effectiveness can’t be chalked up to the possum’s acting skills. Opossums have no control over when they play dead or for how long they do it.
