  • Secretary Birds

    This bird looks like it was a normal stork but someone decorated it and dressed it up. The name of this bird also has a funny meaning behind it. The secretary bird can be found in the savannas of Africa and likes to be in places with spread out acacia trees. They spend most of their time hunting for prey and go back to their trees to roost. The bird's diet includes rodents, insects, frogs, lizards, small mammals, and they especially like snakes. The birds’ latin name is sagittarius serpentarius which means “the archer of snakes”.
    Since the secretary bird is quite a large bird they don’t have any natural predators. Other birds like crows and ravens steal their eggs to eat. Secretary birds are monogamous meaning they have the same mating partner for life. The secretary birds elaborate features are important to their mating ritual, the birds attract mates by doing aerial displays where they fly up and down. The birds name has a funny meaning behind it, it’s thought that it's called the secretary bird because secretaries used to tuck pens in their hair and it resembles the bird's feathers.
    The bird has a lifespan of around 15 years and has grey plumage all around its body but has a black tail and legs. Its eyes are yellow and it has black feathers resembling quills around it’s head. This bird also has feathers around its eyes that resemble eye lashes.

  • Tokyo Gecko

    Today, we will talk about the Tokay Gecko, a striking and unique lizard found in many parts of Asia.
    First, tokay geckos are very large, and can grow to be up to 30 centimeters long. They are robust, with large heads, muscular jaws, a prehensile tail, and bodies that resemble flattened cylinders. They have foot pads that let them climb up walls with ease. Their skin is soft, and mainly grey with orange-red spots. They can also have light spots on their body, and light bands on their tail. Male geckos are larger and more brightly colored than females. They have a bright pinkish-red mouth, and yellow eyes with vertical pupils.
    Tokay geckos are known for the male’s mating call, which sounds like their name. It is described as sounding like token, gekk-gekk, tuck-too, or poo-kay. These sounds are also why the family name is gecko. This loud call usually starts with a low-pitched cackling. When a tokay gecko feels threatened, they will let out a bark and open their mouths, showing they are ready to fight.
    Tokay geckos are found in many places in India, Bhutan, Nepal, and Bangladesh. They are also found in Southeast Asia, in places like the Philippines, Malaysia, and Indonesia, and also to western New Guinea. They are found in rainforest areas, in places like trees and cliffs, but they also live in rural areas, living on the walls and ceilings. The tokay gecko has been introduced to places like Florida, Martinique, the islands of Belize, and possibly Hawaii.

  • Frogfish

    Hello,this is Wild Suzhou.

    Today, wewill be talking about frog fish, which refers to any member of a family offish, Antenariidae. They are a type of anglerfish, and are found in shallowtropical and subtropical waters.

    First,frogfish are very small. They look like squatting frogs, which is where theygot their name from. The largest only grows to be around 30 centimeters. Theyare round, lumpy fish, with large mouths. Most species of frogfish have pricklyskin, too. They have specialized front fins, which look like legs and also letthem walk along ocean floors looking for food.

    Frogfishare excellent when it comes to disguise, and have multiple ways of stayingconcealed, from both enemies and prey. Some species, like Commerson’s frogfish,have roughly textured skin that resembles coral, and can even change the colorof this skin to match their surroundings. The psychedelic frogfish has strikingyellow, brown, and white stripes that help it blend in with another kind ofcoral. The hairy frogfish has long, waving appendages that look like plants.This camouflage is extremely effective in hunting prey, since small fish andanimals can swim by the frogfish, unaware that they are about to get eaten.This is called aggressive mimicry, since the frogfish mimics, or pretends to bepart of its surroundings so that it can attack its prey more effectively.

    On top oftheir wonderful camouflage, you have to remember that frogfish are a type ofanglerfish, which means they have a special type of fin on their head, calledan illicium, that acts like a fishing rod. This fishing rod has a “bait” orlure on it, which can look like a small fish or worm, like a bait that afisherman would use to catch fish. Sea animals are attracted to this lure, andwhen they get close enough, the frogfish swallows them whole. They swallowtheir prey so fast that it can’t be seen with the human eye. Sometimes, thestill living fish can be seen moving around inside their stomach before itdies.

  • Northern Hairy-nosed Wombat

    The northern hairy nosed wombat is a memberof the wombat family, it’s the largest, but also the rarest.

    This wombat species can be found only inparts of Queensland, Australia. They live in sandy areas that have a lot ofgrass. They dig burrows in the soil to live in. It’s diet is just grass andthey spend most of their time eating.

    The northern hairy nosed wombats predatorsare mainly dingoes. In their reserves there are fences to stop the predatorssince they are so endangered.  When these animals feel threatened,they will run away or go into a tunnel and block of the entrance with theirhump. They are actually quite fast and can run up to 25 miles per hour.

    This species in endangered due to smallpopulations, over predation, habitat loss, and droughts.  There areonly about 100-200 in the wild left. These rare animals can weigh upto 40 kilograms and are approximately a meter long.

  • Bluebottles

    Hello,this is Wild Suzhou.

    As achild, I remember going to the beaches in Australia, and seeing these brightblue balloon-like objects washed up onto the shore. People would usually drawcircles around them, and I would help draw them too. Though they looked cool,everyone knew not to touch them, unless they wanted a very painful experience.

    The blueballoons are known as bluebottles, or the Indo-Pacific Man O War. They have asimilar, deadlier relative, known as the Portuguese Man O War. They look likejellyfish, but are actually siphonophores. It’s a colony of polyps that allwork together. In this sense, they are kind of like coral, since they’re madeup of trillions of organisms. However, unlike coral, these polyps are not allthe same. Different groups of them have different functions, kind of likeorgans. In this sense, the bluebottle is like one animal.

    There arefour groups of polyps that make up the blue bottle. The first one, usuallycalled “the float”, are the polyps that make up the gas-filled sac that lookslike a balloon.
    Another group of polyps make up the stinging tentacles, which catch food byparalyzing prey. These tentacles can grow to be up to 10 meters long. Paralyzedprey is transferred to digestive tentacles, another group of polyps.Reproductive tentacles produce sperm and eggs, which grow into larva, or young.These larvae will divide themselves many times, each time doubling the amountof polyps. They do this until there are enough cells for a new colony and newblue bottle to be formed.


    Not manyanimals prey on blue bottles, but some species of nudibranch, a type of seaslug, and also sea snails, feed on them. One species of nudibranch, known asthe pacific blue glaucus, has a diet that consists almost entirely ofbluebottles. They also store the stinging cells of the bluebottle, which theycan use as a defense against their own predators.

  • lyre Birds

    lyre birds can be found in Southeast Australia. It’s spends theday roaming around on the forest floor, and spends the night up in the trees.These birds eat mostly insects and other small animals. The way they find foodis by using  theirlong claws to forage among the leaves and soil. 

    The predators that pose a threat to lyre birds are quolls, dogs,feral cats, goannas, and foxes that eat their eggs. Lyrebirds defend themselveswhen they feel threatened they make loud shrieks and try to run away from thethreat. Lyre birds are special because they have the ability to mimicartificial and natural sounds, such as other birds, and car sounds. They usethis skill to attract mates during mating season. 

    The name also has an interesting meaning. It’s called the lyrebirdbecause the males tail feathers resemble a greek instrument called the Lyre.They have a lifespan of 30 years, and they can start mating around the age of6. The male lyrebird has an elaborate tail with long feathers and the femalehas a shorter tail.

  • Roadrunners

    Today, wewill be talking about the roadrunners, which consists of two extant species,the greater roadrunner and the lesser roadrunner.

    Roadrunnersare usually about half a meter in length, and weigh about a third of akilogram. They are large, slender birds with long necks, tails, and legs. Theirfeathers are black and brown, but have lots of white streaks running throughthem. They have a large, dark bill, a patch of blue and or red skin behindtheir eyes, and a dark crest with white spots or streaks. The greater andlesser roadrunner are very similar to each other, the main difference would bethat the lesser roadrunner is the smaller of the two species.

    Roadrunnersare very fast, running at speeds of up to 32 kilometers an hour. Because ofthis, they prefer to sprint rather than fly, even though they can do both.

    Roadrunnersare omnivores and there are a lot of things that they will eat. They willmainly eat insects, but they can also eat reptiles, small mammals, spiders,scorpions, small birds, eggs, and plant materials like fruits and seeds.Roadrunners are very active, and will run and jump to catch prey. They willalso batter, or hit prey against the ground repeatedly to kill it. Roadrunnersare so fast that they are able to prey upon rattlesnakes. They are also able toeat tarantula hawk wasps, a type of parasitic wasp with an extremely painfulsting.

  • Clown Fish

    Clown fish can be found in oceans around the world such as a hePacific, Indian, and the info pacific. Their habitat is warmer waters that havecoral reefs and specifically anemones for them to live in. Clown fish live ingroups called schools. 

    Clown fish eat algae, plankton, worms, and other smallcrustaceans. These fish’s predators are fish, sharks, eels, and humans whocapture them. They protect themselves by staying in anemones that can stingother animals that touch them. But clown fish have a mucus coating in theirskin that protects them from getting stung. 

    something interesting about the clownfish is that they are allborn male but can change genders when it comes time to breed. They live foraround 6-10 years. They are orange with white stripes that may beused to warn predators that the anemone they are in is poisonous.

  • Killer Whale

    Today, wewill talk about the killer whale, also known as the orca. These large predatorsare part of the oceanic dolphin family, and can be found in almost every oceanand sea on earth. Killer whales are found in all oceans and most seas on Earth.Because of how widespread the species is, it’s very difficult to figure out howthe species is distributed among the planet.

    Killerwhales are the largest extant member of the dolphin family, with large malesgoing up to 8 meters in length, and can weigh more than 6 tons. Their pectoralfins, which are like their forearms or forelimbs, are short and rounded. Theyhave large dorsal fins, or fins on their back, and males typically have dorsalfins that are twice as big as females. Killer whales are mostly black, with awhite chest, sides, and patch behind their eyes. They have a dark grey patchbehind their fins, which kind of looks like a saddle. They have a thick layerof blubber, or a layer of fat, beneath their skin, which helps to keep themfrom freezing.

    Killerwhales are apex predators, which means they are at the top of the food chain,and there are no other animals that prey on them. They are similar to wolves inthe way that they hunt, since both animals like to hunt in packs, rather thanby themselves. Because of this, they are often called “the wolves of the sea.”There are a variety of things that killer whales would eat, which is probably aresult of how widespread the species is. They will hunt many species of fish,such as salmon and herring. Herring are often caught using a method calledcarousel feeding, where a group of killer whales will force a school of herringinto a ball. They then slap the ball of fish with their tails, which stuns orkills them, making for an easy meal. Killer whales will also hunt sharks, otherwhale species, birds, sea turtles, seals, mammals, and cephalopods.

  • Pygmy Marmoset

    When you first see this animal you may think it’s a few animalsphotoshopped together, but it’s really just one. 

    The pygmy marmoset is native to south america. They can be foundin the rainforests of Brazil, Colombia, peru, Ecuador, and Bolivia. They spendtime hiding among the plants. They live in small groups of up to 15 others.Marmosets eat mostly insects, fruit, and tree sap. 

    Pygmy marmosets find food by using their good climbing skills toforage in the trees. These animals are very small they have a lot of predators.Some include cats, eagles, hawks, and snakes. The way they protect themselvesis by making loud screeches and noises to scare the predator away.  

    Pygmy marmosets are special because of their miniature size. Theyare usually about half a foot or 12 centimeters. They are one of the smallestmonkey species in the world. They have a lifespan of around 12 years, or 16 incaptivity. There are around 2,500 pygmy marmosets left in the wild. They areshaped somewhat like an egg and have brownish grey fur all over their bodies.
