Elk, warthogs, hippos, narwhals, walrus, sperm whales, and orcas also belong to the elite ivory club. One animal that might surprise you that doesn't grow ivory— the rhinoceros. Their horn is actually made out of the same protein as their hair and toe nails. 🐗 Ivory is made from a material similar to the bone in our teeth and develops into tusks. Ivory gives these species an evolutionary advantage and serves a variety of purposes: digging, lifting objects, gathering food, stripping bark from trees to eat, and defense.

It's strange to think a whale can't just open its mouth and swallow the water it's swimming in- but all that salty sea water can have the same harmful effects on their bodies as ours. The fresh water they need is instead absorbed from the food they eat. 🐳 So when they open their mouth to feed how do whales keep from swallowing an enormous amount of salt water with the tiny krill and fish they're catching? They have a special structure in their mouth called baleen- that's what all those bristles are for that line the top of their mouth. Those bristles act like a broom and they're perfect for straining out water. Before the whale swallows its food it uses its tongue to push all the extra water out through their baleen; the bristles keep the tiny krill trapped inside their mouth while just the saltwater is strained back out. [Compared to their size whales also don't require as much water as humans because they don't sweat and loose water like we do on dry land.] #science #biology #nature #wildlife #underwater #whale #diet #hunting #fishing #dinosaur #strength #swimming #fish #hunter #sushi #scuba #dive #diving #calories #vegetarian #shrimp #ocean #cooking #net #dolphins #learning #teacher #teachers #natgeo #nationalgeographic

If you look closely here you can even see one of them looking out over the top edge. The largest nest on record measured over 9.5 feet across and 20 feet deep. It's not hollow inside- it's made of solid sticks they've collected adding up to over 2 tons of material. How does it get so big? Eagles mate for life and will return to the same nesting site every year; if their old nest is salvageable they will work together making repairs and add too it. Year after year the same pair of eagles add to their old real estate- one of my students described their nest as a "bird mansion" haha. 🐣
Their homes are so large that smaller birds like sparrows will even sneak their nests into the bottom edges of it; the eagles ignore them because of their small size— but the sparrows benefit from living under a bodyguard. The eagles will chase away mutual enemies they share with the sparrows like jays and crows as they focus on defending their own nest. It's a great example of a symbiotic relationship in nature. 💪🏼 #nature #wildlife #eagle #nest #science #biology #egg #eggs #eagles #american #america #nursery #feather #feathers #hunt #hunter #fishing #dinosaur #meat #natgeo #learning #flying #baldeagle #mansion #claws #dreamhome #nationalgeographic #wildlifephotography #treehouse #birds

Look closer— it's not created from their feet paddling or their breath- it's coming out of their feathers. Before a penguin dives it will trap air between the feathers on its body; while underwater it can control when the bubbles are pushed out- creating a thin slipstream. The bubbles reduce the friction of the water on the penguin's body, and acts like a turbo boost when chasing fish or exiting the water. 🐟

Actually a very famous one: remember the feeding scene in the last Jurassic World where they're lowering the shark into the water tank and the giant Mosasaur comes up and swallows it whole? Mosasaur- the giant seagoing lizard's fossils have been discovered in Antarctica. 🐋 But how could dinosaurs survive at the South Pole? They were cold-blooded so they actually couldn't; but during the time when dinosaurs ruled the Earth– Antarctica had not yet drifted to its current polar location. Dinosaurs roamed around on a super continent called Pangea, which was a giant land mass that all the continents fit together in like a puzzle. During the Jurassic period massive earthquakes underground started to break the land up and it diverged apart. The land we walk on is actually floating around on a lot of liquid magma deep underground and it's always moving around and readjusting itself. This is still occurring today but it happens at such a slow pace it's barely measurable. The Mariana Trench, the deepest known part of the Pacific Ocean, is caused from these land plates still pulling apart. (Incredible to think our planet is mostly a ball of lava that we are flying around the solar system and living on!) There's a lot of great fossil evidence to support the Theory of Pangea if you'd like to learn more:

Scientists have debated a long time about the purpose of this whale's giant tooth; some speculate it's used in dueling matches to attract a mate, others argue that it's like an antennae for sensing changes in the Arctic water and finding food. There isn't any evidence that the narwhals use this physical adaptation as a defensive weapon against predators (like polar bears and killer whales.) 🐘 If you follow environmental news you might've seen the huge anti-poaching demonstration in Kenya last weekend. More than 100 tons of confiscated ivory was stacked up and burned by their president to demonstrate to the world that ivory from its elephants has no value, and tusks will no longer be supplied to the black market. Whether or not the destruction of this ivory will help save elephants or effect the global demand for tusks— Kenya sent a clear message about the dangers of wildlife poaching.

The dark patches on a giraffes body blend perfectly with the shadows of the branches under the hot African sun. Animals like zebras and wildebeest have to travel long distances during the dry season to find fresh grasslands when the rains stop; but giraffes don't migrate like other herd animals of the Savannah. Instead, they eat mostly leaves from trees which aren't as effected by drought as the grass is. This helps them in two ways: they have a food source they don't have to compete with other species for, and they don't need to spend energy traveling on a dangerous annual migration when everything else dries up. Predators like lions still need to hunt when the herds leave, and giraffes have several advantages to stay one step ahead of them. Their 18 ft. tall body gives them a commanding view of the landscape, but it also makes them easy to spot on the open horizon. Since most of their time is spent in the woodlands eating leaves, they've been given the perfect camouflage to blend in with that type of habitat. Along with a very powerful kick and fast speed- most predators would need to be pretty desperate or bold to attempt making a meal of one of these towering animals. 🌳🦁 #science #wildlife #biology #nature #giraffe #camo #camouflage #lion #lions #zebra #elephant #leopard #branches #branch #leaf #leaves #hunting #hunt #hunter #vegetarian #veganfood #diet #africa #natgeo #nationalgeographic #africa #tall #woods #teacher #teachers

Portrayed as thieves and scavengers they are often seen as the villains of the African Savannah. Hyenas are actually efficient hunters and they're always the underdogs to their nemesis the lions. In fact, statistically more meals are stolen from hyenas by lions than the other way around. They're mislabeled as scavengers, but more than half of everything a hyena clan eats is what they've hunted and killed for themselves. Hyenas are very messy eaters and mealtime can look very savage, bloody and barbaric to outsiders. Often hyenas are seen eating their prey alive but that's because they lack sharp claws that big cats secure and hold their prey down with. In truth neither lions or hyenas have easy lives on the Savannah and both species will steal a meal when there's an opportunity for survival. 🐗 🌍 Unlike most social animals, hyena families are strictly led by females and the males are left virtually powerless and subordinate. Dominance among hyenas isn't fought for but typically inherited and very rigid. Each clan has a queen who gets first-priority at carcasses and her young is treated with high respect among the rest of the group. Being born a hyena isn't an easy life; but their cooperation is a great example of how teamwork among a group can often lead to success. Every animal on the Savannah, big and small, knows to be wary when they hear the hyena's haunting calls in night. 🙈

Falcons have been recorded diving at speeds over 240 miles per hour (386 km/hr.) As a biologist I know I'm not supposed to have favorites, but falcons are one of the animals I could spend hours talking to my students about.
As a member of the birds of prey family (including hawks, eagles, and owls) falcons inherit the ability of speed— but what really makes them impressive is their specialty of capturing other birds in mid-flight. Built like fighter jets they must be able to dive and out-maneuver their prey in the sky; this requires much more skill than a predator on flat land. 🌤 Flying up into the clouds, falcons will sneak up on their prey from high above. When they spot an opportunity they'll fold their wings and dive at speeds over 240 mph, collide with their prey in mid-air, and capture it with their razor sharp talons. They prefer a habitat of sheer cliffs for raising their young where they have a safe and commanding view of the landscape; this actually makes them very adaptable to living in big cities among sky scrapers. In places like New York City they're a welcome guest among residents for controlling the pigeon population. In the spring many falcon parents can be found building nests and raising chicks on sky-rise balconies. In a world where most animals are struggling to keep up with changes in their environment- it's reassuring to see a species adapting so well to urban life among humans.

One of my favorite extra credit questions to put on an exam: What's the difference between venom and poison? Both of these words are used interchangeably by people but there are some important differences. •Venom is injected into its victim with a bite or a sting. A cobra's fangs, a spiders bite, a scorpion or hornet's stinger, and the barbs on jellyfish tentacles are all mechanisms that can deliver venom into the bloodstream. 🐍
•Poison must be either eaten or absorbed through the skin. A poison dart frog must be touched to deliver its toxin, the same goes for the irritating oils on a poison ivy plant. Salamanders secret a poison that upsets the stomach of a predator if they're eaten, just like some dangerous wild mushrooms. An assassin would mix a deadly poison into the drink of his victim. ☠
In other words, there's no such thing as a poisonous snake, to be accurate they should be called venomous. None of them are harmful if their leathery skin is touched, they must use their fangs and bite to be deadly. 💉
