An annual global event World Ocean Day: Eyes on 4 critically endangered marine species: On an auspicious day, World Ocean Day, we have rounded up 4 marine species that are at a high risk of extinction in the wild. World Ocean Day is a way to spread awareness about the importance of the ocean in our life and also focus on challenges to preserve this precious environment.
As we know Oceans produce more than half of the world’s oxygen which means they are life –providers for us. And what we are doing to save the marine life and their habitat. We are doing nothing just occupying the ocean base with lots of harmful chemicals and human waste. Is it fair?
Overfishing and bottom trawling are the second reason for damaging marine life as in this fishing practice they dragged the heavy net to catch the fish from the bottom of the ocean. The practice is permanently damaging the marine ecosystem.
Here are the endangered marine species:-
Great hammerhead shark (Sphyrna mokarran):- The iconic marine species are known for their distinctive mallet-shaped heads. Normally, they can survive for about 20-30 years and reproduce every two years. They targeted their fins during fishing.
European eel (Anguilla Anguilla):- They are the fish with a snake- structure, Their length is about 1.3 metres (52 inches) and weigh up to 6.5kg (14.5lbs). They move from the freshwater streams back to the Sargasso Sea to spawn and die after getting sexual maturity. Construction of dams and overfishing are the major hurdle to their migration and also the major cause of a high decline in their population.
Sunflower sea star (Pycnopodia helianthoides):- This is the largest sea star all over the world. They have 16 and 24 limbs, which can each grow up to a metre (39 inches) in length. 90% of the species have vanished for last. 30 years. Wasting syndrome is the main reason for their highly decline. The formation of these wasting syndromes is not clear but it has been reported that the warming temperature has played a major role in their production.
Angelshark (Squatina squatina):- Usually they are found in the eastern Atlantic and the Mediterranean Sea. They can survive for 15 years and grow up to 2.5 metres. They lay at the bottom of the sea and are easily caught during the overfishing practice. 80 % of their population has decreased during the past century.
