Cuttlefish


Cuttlefish (Sepia officinalis) are masters in altering their appearance in order to blend into their environment.

Mangroves are small trees which grow in coastal saline or brackish water. Having grown in a tropical peninsula by the sea I have developed a deep passion for mangroves not only for its beauty but more importantly because of its role in biodiversity. I love seeing colourful carbs growing up there, marine snakes, and all sorts of tropical fishes.  Considering the place were I am from there would be no hope for me but to love mangroves.

The green sea turtle (Chelonia mydas) of the Cheloniidae family is a genus of large sea turtle. It is the only species within the Chelonia genus. Its range stretches all over the world across tropical and subtropical seas, with two distinct populations in the Atlantic and Pacific Oceans, but is also present in the Indian Ocean.  Adult green sea turtles prefer to live near seaside grass beds, mangroves and coral reefs while younger ones live further away from shore. Green sea turtles are one of the largest turtle species in the world, weighing about 65-130 kg and ranging between 1-1.2 m in length.

Spotted eagle ray

Spotted eagle ray  The spotted eagle ray ( Aetobatus narinari ) is an eagle ray from a family of cartilaginous fish, Myliobatidae. Spotted eagle rays enjoy swimming in seas at a temperature of 24 to 27 ° C, and are more active in high tides. They are timid creatures who usually avoid humans, but they were seen jumping on boats and falling on people from the sea. Searching for their food, they dig their snouts into the sand on the seabeds. Groups of them consist of about 6 participants swimming at exactly the same speed in the same direction.
