Did you know that there are more than 140 species, or unique types, of dragonflies in Ontario?

Each species of dragonfly requires a specific environment for it’s habitat. Some dragonflies prefer ponds, others prefer lakes, some dragonflies require slow-moving streams, others prefer fast-moving streams, and yet others prefer marshes. Ontario is also home to one of the world’s most rare dragonflies, Hine’s Emerald dragonfly. Dragonflies are also our friends because they eat small winged insects as a main staple of their diet, so there are fewer mosquitoes because of them. What kind of dragonflies live in your area?

A Fish Out of Water

The African Lungfish (Protopterus annectens) lives in flood plains, which can be tricky in drought season, as the water dries up most aquatic species would be in trouble. Luckily this smart fish has developed a way to breathe even when it is out of the water by secreting a thin slimy film that it covers itself in. This slime dries into a fragile cocoon that the fish can live in for over a year.

Catching up with a Kakapo

The kakapo (Strigops habroptila) is a very unique bird, for one thing it is a nocturnal parrot, so just like cats they are active at night. But don’t think that means they are out flying around under the night sky because this bird is the only flightless parrot in the world!

Although the kakapo can’t soar in the sky it is a good tree climber, using its wings as a kind of parachute as it jumps from the trees to the ground. So where does this giant flightless night time loving bird live? The kakapo once lived all across New Zealand, but as this bird started to disappear the remaining survivors were moved to islands off the coast of New Zealand where they could be better protected. This species is listed as critically endangered because today there are only around 122 kakapos left in the world!

Taking BIG bites

We all know that sharks are expert hunters but did you know they are also good biters? Great white sharks (Carcharodon carcharias) have a group of muscles in their jaw that allows them to have strong bites no matter how wide open their mouth is. New research has shown that sharks may not be born with this expert biting ability and that it might actually develop over time. This study showed that teenage great white sharks are awkward biters because their jaw muscles haven’t developed to the point where they can hunt large prey.

Biodiversity Loss is Bad for your Health

Biodiversity Loss is Bad for your Health

When you get a tickle in your throat, the adults in your life might say that you got sick because you didn’t dress warm enough or eat all of your veggies. Have you ever thought that a lack of biodiversity might have also played a role?

You see, ecosystems that have lost much of their biodiversity become more vulnerable to invasive species and can run rampant with infectious diseases. For example, mosquitoes are kept in-check by insect-eating animals, like frogs. So, if frog populations were to decline because of human pressures, we have a lot more mosquitoes. And with more mosquitoes, there could be an increase in the spread of nasty bugs like the Bird Flu and malaria. Adding to this, the shrinking of habitats puts humans in closer contact with wild species that can transmit new types of diseases to us. Yikes!

Prescribing Biodiversity

Now that we know biodiversity keeps us healthy, it’s time to take action by prescribing a little biodiversity protection for everyone. You can help by protecting animals and their habitats with a Bring Back the Wild Campaign, spreading awareness about species at risk, and doing your part to live green

Diving Turtles

Leatherback Turtles (Dermochelys coriacea) are expert divers who plunge down into the ocean to catch food and cool-off from the hot tropical sun. But how do these reptiles move through the water: do they exhale all their air and sink to the bottom like a rock, or do they doggie-paddle their way to the bottom? To find out, water-proof trackers were attached to five female turtles in the wild. The information that was collected from them gave scientists a really good idea about how these turtles dive.

It was revealed that the Leatherbacks, unlike many other diving animals, dive with their lungs full of air. As they go down into the ocean, the air inside their bodies gets compressed and they achieve something called neutral or negative buoyancy (which basically means there body density matches that of the water). At this stage, they can move through the water without having to fight the force of positive buoyancy; allowing them to easily glide deep underwater. When they’re ready to return to the surface, all they do is swim upward until the air in their bodies expands and carries them to the surface. You could say they’re like miniature submarines – so cool!

Ballooning Whale

The Blue whale (Balaenoptera musculus) is able to stretch its mouth cavity along specially designed groves on its throat to take in its own weight in water, so a 90 ton whale could take in 90 tons of water! Once a Blue whale has filled up they will filter the water for krill (a small shrimp-like crustacean), then let the water out and mow down on some tasty krill, 6-7 tons a day to be exact!

Saving the Bluefin Tuna

These amazing swimmers are in some serious need of protection. The Atlantic Bluefin Tuna (Thunnus thynnus) is critically endangered; it’s so overfished that if we don’t do something to protect it soon, it’ll likely go extinct within our lifetime! Also, if the Bluefin Tuna disappears from the Atlantic ocean, they may be gone for good because it doesn’t like living in captivity.

Top Fin Facts

Body Builders – The Bluefin Tuna is big and strong, with an average length of 458 cm and a maximum weight of 684 kg. It’s also built for speed, having a torpedo-shaped body jam-packed with muscle. This comes in handy when it needs to catch prey and travel super-long distances across the Atlantic ocean.

Making Friends– Bluefin Tuna hang-out in schools and it’s not uncommon for different species of tuna to swim together.

Old and Wise– Wild Bluefin Tuna usually live around 15 years, but the longest lifespan is estimated at between 20 and 30 years!

Baby Tuna– Atlantic Bluefin Tuna breed once a year, and migrate to either the Gulf of Mexico or the Mediterranean Sea to spawn (that is, lay eggs).

Butterflies have tiny hairs on the bottom of their feet that let them taste sweetness. When a butterfly is very hungry they are expert sugar detectors, 200 times more sensitive than the human tongue.
