List of Ocean Plants Kelp Kelp grows in cold coastal waters. It is the largest marine plant in the world and can reach up to 250 feet. Kelp is also the fastest-growing plant in the world. Kelp is typically brown and lives on the surface of the ocean. Seaweed Seaweed is a form of microscopic algae called phytoplankton that floats on the surface of the ocean, much like kelp. Seaweed has been harvested by humans for thousands of years as food, material for housing, rope and baskets. A surplus of seaweed can choke out coral reefs. Seagrass Seagrass grows in shallow water because it needs lots of sunlight. Seagrasses provide habitat for small fish and other young marine life such as lobsters. Red Algae Red algae grows in warm tropical water. Coralline Algae Coralline algae consists of very fine filaments that grow over rocks. Coral and Algae Coral is not a plant; it is an animal organism.
Un ours, un lion et un tigre devenus amis pour la vie Aux Etats-Unis, le centre Noah's Ark qui recueille des animaux est depuis plusieurs années, le témoin d'une amitié inhabituelle entre un lion, un tigre du Bengale et un ours noir, devenus inséparables. L'histoire est digne d'un film de Walt Disney et pourtant, bon nombre de visiteurs ont pu le constater, elle est bien réelle. C'est au centre Noah's Ark située en Georgie aux Etats-Unis que l'histoire se déroule. Cette organisation a pour but de recueillir et prendre soin d'animaux orphelins, abandonnés ou maltraités. Mais trois des pensionnaires du centre attirent particulièrement l'attention. "C'était encore des bébés, ils étaient nourris au biberon" et avaient à peine deux mois, se souvient Kandi Allen du Noah's Ark. 12 ans sans conflit Quand les animaux ont été recueillis, ils ont été soignés puis naturellement placés dans des enclos séparés. Baloo, Leo et Shere Khan (le tigre du Bengale) se sont calmés et se sont mis à jouer entre eux. Des journées passées ensemble "Cela fonctionne.
Le blog de Joconde - Portail des collections des musées de France Life Cycle of a Frog True Love? When Frogs mate, the male frog tends to clasp the female underneath in an embrace called amplexus. He literally climbs on her back, reaches his arms around her "waist", either just in front of the hind legs, just behind the front legs, or even around the head. Amplexus can last several days! Usually, it occurs in the water, though some species, like the bufos on the right mate on land or even in trees! Spawn (egg-mass) While in the amplexus position, the male frog fertilizes the eggs as they get are laid. Egg Frogs and Toads tend to lay many many eggs because there are many hazards between fertalization and full grown frogness! Tadpole Shortly after hatching, the tadpole still feeds on the remaining yolk, which is actually in its gut! Tadpole with legs After about 6 to 9 weeks, little tiny legs start to sprout. Young Frog, or Froglet By 12 weeks, the tadpole has only a teeny tail stub and looks like a miniature version of the adult frog. Frog Back to Strange but True Facts.
Ocean Biome Animals A walk on the wild side: 7 fascinating experiments in rewilding George Monbiot gets in touch with his rewilding side at TEDGlobal 2013. Photo: James Duncan Davidson George Monbiot begins today’s talk by recalling a time he was “ecologically bored.” “We evolved in rather more challenging times than these, in the world of horns and tusks and fangs and claws,” explains Monbiot, an investigative journalist who found himself deeply dissatisfied returning to the United Kingdom after years reporting in the tropics. George Monbiot: For more wonder, rewild the world“We still possess the fear and the courage and the aggression required to navigate those times. But in our comfortable, safe, crowded lands, we have few opportunities to exercise them without harming other people.” In his search for a solution to this stupor, Monbiot discovered his current passion: rewilding. It’s a term, coined by activist Dave Foreman and broadened by Michael Soulé and Reed Noss in the 1990s, that Monbiot explains has two meanings.
Universe Explorers | 19-year-old inventor finds way to clean up the world’s oceans in under 5 years time By: Jack Taylor, Guest Previously the idea of cleaning up the world’s oceans with their vast accumulations of disposed plastic material was considered an impossibility. Now a 19-year-old inventor says he and his foundation has a way to clean up the world’s oceans, and not only does he say we can do it, but that we can do it in five years time and produce a profit from it. It is called the ‘Great Pacific Garbage Patch’ or sometimes the “Pacific Trash Vortex”, and it is a massive collection of plastic particles accumulating in the Pacific. Other oceans have their own collections of plastic wastes as well; furthermore, most of the debris in our oceans are plastic materials that accounts for approximately 90% of all the waste debris. Scientists have considered all manner of ways how the debris could be retrieved but there was no clear answer for it. The angle with how the array is set up allows all of the plastic to go to where the platforms processing centers are floating. Source: vr-zone.com
Life Cycle of frogs The Egg Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn. The large and slippery mass of eggs are too big to be eaten. This is nature's way of protecting them. The egg begins as a single cell. The Cell Splits The single cell in the egg eventually splits into two. The Embryo The mass of cells in the egg come to form an embryo. The Tadpole After its 21 day development period, the embryo leaves its jelly shell, and attaches itself to a weed in the water. The tadpole has a long tail, and lives in the water. The Tadpole Begins To Change After about five weeks, the tadpole begins to change. Almost There . . . Over time, the tadpole becomes even more froglike. The Frog Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water.
