Humboldt Squid: Red Devils Of the Deep Sea

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. During this lifetime, Humboldt squid reproduces via internal fertilization and can lay eggs of over 1 million. The female can lay as much as 20 million eggs during this short time. They can grow from 1 millimeter to 2 meters in just a span of one year and can weigh up to 50 kilograms after they hatch. 

The population of Humboldt squid has been massively increased. Previously they used to live only in the cold waters, where we can find them from Peru to central Mexico. But now they have stretched through Chile to Alaska. Due to the increase in temperatures, they are making themselves adaptable to the hot waters. Despite well known and studied species, their conversation status is unknown.

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...

What Gives More Oxygen on Planet Earth?

Image
Everybody knows that plants and trees produce oxygen for the earth. But, do you know that oceans and seas contribute more oxygen. Produced by marine plants, algae and single-celled organisms called phytoplankton. These may not be seen by the naked eye but produce more, which is not even close to the proportions produced by the trees and plants. The ocean produces oxygen as a by-product of photosynthesis, which converts sunlight and carbon dioxide and can use as energy. One type of plankton, Prochlorococcus releases tons of oxygen into atmosphere. So small, that can millions can be present in a single drop of water. It produces 20% of the oxygen to the earth biosphere, which is more than the rainforests on land combined. Scientists mention that a single cell can give oxygen for one in every 5 breaths we take. Calculating the amounts of oxygen on oceans may vary because of the change in climate conditions, geographic location and with the tides. It is also important to remember that the...
