Tamilnadu Government declares India's first #Dugong Conservation Reserve at Gulf of Mannar & Palk Bay. Conserving dugongs means conserving it's habitat. Seagrass meadows is an important habitat in focus here.

This thread is all about Seagrasses

Video @BERTIEGREGORY
Seagrasses are marine flowering plants, found on all continents except Antarctica. They have roots, stems, leaves, flowers &fruits, similar to land flowering plants (angiosperms) 2/n
Seagrasses are found along the coast, in clear, shallow waters that allow light for photosynthesis, to penetrate. Some species occupy the intertidal zone, the area between the highest tide line and lowest tide line,from which the sea retreats at low tide to expose the seabed 3/n
Dense seagrass growth traps flowing sediment and nutrients. Seagrasses form the basis of one of the most productive ecosystems of the world, providing food and shelter to a diverse community of animals. 4/n
The leafy canopies support a range of tiny plants that grow as epiphytes (like moss on trees) and small marine invertebrates, which in turn attract sea anemones and fish, and megaherbivores like green sea turtles and dugongs. 5/n
Sediments can choke the leaves and dredging can completely fragment seagrass meadows. Boat anchors and large marine debris can kill sections of seagrass meadows.

Overfishing also causes a chain reaction, disturbing the seagrass food web in multiple ways. 7/n
Without fish, the sea urchin population explodes, and they can overgraze the meadows. When large carnivorous fish like sharks are removed, intermediate predators that eat invertebrates become more abundant, wiping out helpful pollinators and other small creatures. 8/n
An increase in herbivorous fish also kills off the seagrasses. In India, the sea grass beds are endemic to the specific zones shown in the image below. Incidentally, dugongs are mostly sighted in these zones only. 9/n
Seagrass is an important component to estimate Carbon Storage. 2/3rd of seagrass biomass is buried as rhizomes and roots that sequesters carbon for centuries, thereby slowing global warming. When it is destroyed, oxygen reaches the buried material oxydizing the carbon to CO2 10/n
Seagrasses stores twice d amt of organic carbon per hectare as terrestrial soils. Though seagrass biomass is small compared with forests, d amt of carbon they store in soils is as high as that stored by terrestrial systems &mangroves.

Dugongs presence indicates the spread of seagrass. They feed by excavating and cropping the seagrass that leaves a beautiful grazing trail. It is said that the dugong pop in an area is an indicator of general ecosystem health. Video by Seagrass Watch #greatbarrierreef
Seagrasses are found abundant in Palk Strait &Gulf of Mannar in Tamil Nadu. Out of the 21 islands in the Gulf of Mannar, it is found in Kurusadi, Pumarichan, Pullivasal and Thalaiyari. Restoration works by TNFD at Gulf of Mannar has shown good results.

This thread will detail out the basic information one should know about the Slender Loris and why the decalration of India's first wildlife sanctuary for Slender loris in Kadavur is a milestone measure in the history of conservation.
Usually people confuse between Lorises. There is a myth that Slender Loris is venomous and it's salaiva can kill humans

There are two types of Lorises in India - Slow Loris & Slender Loris. They both belong to primate family and are nocturnal. Slow loris is found in South Asian
In India, Slow loris is spread in the some forests of North East Indian states.
There are two species of Slender Loris,
- Red Slender Loris (IUCN: endangered) found in Srilanka
- Grey Slender Loris (IUCN: Near Threatened) found largely in South India

#Elephant is our national heritage animal. They are represented as drawings, sculptures, paintings and in many other forms. They are closely related to our culture, art, religions & traditions. Have added some of my sketches themed on the unique features of Elephant. Add yours.
The matriarch culture found in the #elephants makes them even better than the most civilised human race.
The young ones are best cared by all the adults and sub adults in the #elephant family.

This World Snakes Day, try to know the popular myths about Snakes and the actual facts behind. All we need to know is, Snakes are crucial part of our ecosystem and we should conserve them. Read Thread!
Myth 1: Snakes Drink Milk

Just like any other animal, they drink water to keep them hydrated. When snakes are kept starved for days and offered milk, they do drink to keep them hydrated. They are cold-blooded reptiles. Forcing them to drink milk could sometimes kill them.
Myth 2- Snakes have Diamond in their head or throat

Just like other animals or us, they are made of cells & muscles. There is no such diamond or any other precious stone in their body. They cannot hypnotise anyone. Lots of snakes are getting killed for these reasons.
