Answer:
West Bengal animals
Mangrove taxa, apart from their morphological characters, have some unique leaf anatomical features which are very much related to their adaptation as the plants grow in unstable, variable and saline environments with regular tidal influence. Special stomatal structures with extended cuticies render the transpiration rate in many taxa. The presence of glandular and non-glandular hairs on the abaxial and/or adaxial leaf surfaces in some taxa are related to salt secretion of these plants. Comparatively large amounts of mater storage tissues occur in the hypodermal or mesophyll tissue of the leaves, reflecting the adaptive nature of mangroves in their stressful habitat. The occurrence of terminal tracheids helps with capillary water storage within the leaf. The coriaceous nature of the leaves in some taxa is due to the presence of sciereids within the mesophyll region. it is noted that Heritiera is unsuitable to the highly saline habitat of the Sundarbans forest region because of some anatomical peculiarities
Explanation:
ladhak animals
The ibex (Ladakhi: skin) is found in high craggy terrain of Europe, North Africa and Asia, and numbers several thousand in Ladakh: trekkers often spot them. The bharal or "blue sheep" (napo) is even more common, ranging in the Himalayas from Ladakh east as far as Sikkim. The Tibetan urial sheep (shapo) is a rare goat found at lower elevations, mostly in river valleys, and therefore is often directly in competition with domesticated animals. They are now rare, numbering about one thousand. The Tibetan argali sheep (nyan) is a relative of the Marco Polo sheep of the Pamirs. Impressive animals with huge horizontal curving horns, they are extremely rare in Ladakh, numbering only a couple hundred, but they do have a wide range throughout mountainous areas of the Chinese provinces of Xinjiang, Qinghai, and Gansu. The habitat of the extremely rare Tibetan gazelle (gowa) is near the Tibetan border in southeastern Ladakh. The musk deer (lhawa) has not been seen in Ladakh for decades if not generations.
The Tibetan antelope, (Ladakhi: tsos, Indian English chiru) is also endangered. Early in the 20th century the chiru was seen in herds of thousands, surviving on remarkably sparse vegetation, but they are vanishingly rare now. It has been hunted for its fine under-wool (Urdu: shahtoosh, Ladakhi: tsoskul), which must be pulled out by hand, a process done after the animal is killed. This shahtoosh is valued in South Asia for its light weight and warmth, but more thananything else, as a status symbol. Owning or trading in shahtoosh is now illegal in most countries.
