Parrotfish live in coral reefs. At night, they blow out streams of mucus to make a slimy sleeping bag. This protects them from sea lice and other small biting pests that like to nibble on snoozing fish. Half-Asleep Dolphins are air-b...
This, combined with the large numbers of seeds produced by grass means that it's able to support one of the largest animal populations on the plantet.Answer and Explanation: There are quite literally billions of animals that live in the grassland biomes of the world with thousands of different...
Native to the US, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed to be the smallest rabbits in the world. Their habitats have been destroyed by development. Several populations, such as the Columbia Basin pygmy, almost went extinct and were saved by...
But it’s not just turtles that thrive on Raine Island. Large populations of seabirds – around 16 different species - also nest and roost there, making it one of the most important seabird rookeries in the world. Coral reefs are also crucial for supporting human life. Due...
Populations of reef sharks, which are important to the health of coral reefs, have declined precipitously around the world in recent years. Caribbean reef sharks can grow to more than 9 feet long, but aren't considered aggressive. I got the shots we needed and climbed out of the water, on...
After you factor in storage and transmission, and the fact that many factories need reliable power around the clock, the cost for clean electricity goes up fast—much more for most countries than for the United States or Europe. Then there’s the second stage: How can we generate heat ...
In large numbers, jellyfish also wreak havoc with local fishing industries by tearing holes in fishing nets and disrupting other fish populations. A smack, or small group, of jellyfish Image courtesy Kevin Connors /MorgueFile Jellyfish do best in their natural environment, but many aquariums ...
Ever wondered how many Tyrannosaurus rex (霸王龙) ever walked around the Earth? The answer is 2.5 billion over the two million or so years in which the species existed, according to a calculation published today in Science. The figure has allowed researchers to estimate just how rare it is ...
Coral reefs are home to 30% of marine biodiversity . 1 km 2 of coral reefs can produce between 10 to 15 tonnes of fish. They therefore represent a vast food reservoir for island populations who derive their protein intake almost exclusively from the consumption of fish. ...
Importantly, given the simplicity of the data collection and the functionality of the data analysis, this method is easily replicable to measure the body size of manta ray populations in other countries and possibly that of other marine megafauna species that spend time at the surface. Drones ...
