Coral Bleaching And Its Effects

Beneath the surface, the ocean is teemed with lot of life rather than any other biodiversity. Corals are the main reason and primary source of life for countless animals. But these reefs have been reached an endangered state because of the human activities. Most of the corals have been wiped out due to pollution, unrealistic fishing activities and climate change.

Due to warm water temperatures, corals reach to a stress sate which results in releasing the algae present in their tissues which makes the coral white. This is referred as coral bleaching, but that doesn't mean the coral is dead. A coral can survive a bleaching event, but if the water warms more it results in the dead of the coral.

In 2005, most of the corals have been died due to extreme bleaching event. This thermal stress is much greater than compared in all the 20 years.

Not only warm waters, even cold waters can result to bleaching. In 2010, cool waters in Florida have been made some serious damage to the coral which cause them dead. The water temperatures have been dropped to 12 degrees which is lower than the typical temperatures.

Coral reefs are the rich ecosystem on the earth. Most of the just know them as home décor and jewelry. But doesn't know that they are made of living things and most of the world doesn't even know they are at threatened stage. It takes decades or even longer to create reef structures. They are the rich source of life and they need to be protected.

Humboldt Squid: Red Devils Of the Deep Sea

Image
Like many other squids, Humboldt squid is one of the fierce predators. These animals are one of the largest squids which have earned the name "jumbo squid". They come in packs from the deep waters after the sunset and hunt for their prey. Possess extraordinary eyesight, a razor-sharp beak, and eight tentacles which makes them catch the prey and tear them apart.  Humboldt squids are the powerful swimmers and the bioluminescence in their skin allows them to change colors. This kind of behavior allows them to communicate and display a warning to the others. Ability to light themselves in colors of red and white during aggressive have earned them the name "red devils". On a very rare case, the individuals attack the scuba divers who were diving in groups of Humboldt squid they were feeding. It has only predator i.e; sperm whales . The Humboldt squid can live only a single year, so they decimate populations of small fishes or smaller squid when they hunt. Durin

The Majestic World Of Dolphins

Image
D olphins are marine mammals that are easily recognized by their curved mouths, which mostly feed on squids and fish. Currently, there are 36 dolphin species and are found in every ocean. The orca often called a killer whale is considered as the largest dolphin which can grow up to 30 feet long. Echolocation For Communication and Hunting Dolphins use a highly sophisticated type of sonar called echolocation which makes them find things that are buried under the sand. This makes them easy to hunt when dolphins approach the surface for air, the sneaky small devils come out. Teamwork and collaboration are the keys to their survival. They communicate with each other in a complex language using squeaks, whistling, and clicks. They carve physical touch with each other.  A dolphin pregnancy lasts between 9 and 16 months, where the mother feeds their offspring with milk. They also train them on how to survive and hunt for their self-being. Cleaning Section You know dolph

Sea Turtles: The Endangered Species

Image
Sea Turtles have outlived almost all the prehistoric animals once they shared the planet. Marine turtles inhabit the oceans open waters and coastal habitats, feeding on jellyfish and other aquatic plants and animals. They are the live representatives of a group of reptiles that traveled our sea for more than 100 million years.  Importance of Sea Turtles These sea turtles have been living for more than 100 million years and maintaining a fundamental link in the marine ecosystem. They maintain the health of seagrass beds and coral reefs that benefit the valuable species such as lobster, shrimp, and tuna. Having outlived million years they can hold their breath up to five hours. They also transfer the vital nutrients from oceans to beaches and dunes. The seven extant species are The Green, Loggerhead, Kemp's Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback, which are endangered. Five of the seven species are found in tropical and subtropical waters. The other two sp
