Lemon sharks belong to the requiem shark family and live in shallow coastal waters of the Atlantic and Eastern Pacific oceans. They are known for their yellowish skin and are named after it. Their closest living relatives are sicklefin lemon sharks.  Lemon sharks rely heavily on mangrove forests during early stages of their lives. Female lemon sharks give birth to live pups near coastal waters to protect them from predators. These newborn sharks spend their initial four years in these mangroves and reefs near coasts. This protects them from large predators that can not enter this shallow water.  After attaining adulthood, lemon sharks move from coastal mangrove forests to inner ocean with up to 90 meters deep waters. However, female lemon sharks later return to the same mangrove forests to give birth to their pups.  Unlike most other shark species, lemon sharks are social animals that generally tend to become part of a group. Many of these sharks prefer companionship o...

  The Arabian Desert is a vast arid region in western Asia . This hot desert covers almost the entire Arabian Peninsula.  The Arabian Desert is Asia’s largest desert and the world’s second-largest hot desert after the Sahara . It covers nearly 900,000 square miles (230,000 square km) in Saudi Arabia, UAE , Yemen, Oman, Jordan, Kuwait , and Qatar.  The Rub al Khali (Empty Quarter) is the largest continuous sandy desert . It is the largest portion of the Arabian Desert, located in parts of Saudi Arabia, Yemen, Oman, and the UAE. Its estimated length is from 560,000 square km to 650,000 square km, nearly double the size of the UK or equal to France. The area contains large sand dunes up to 250 meters (820 feet) high. ( Source ) Apart from the Empty Quarter, there are other smaller deserts inside the Arabian Desert . The two main deserts are the Al Nafud al-Kabir (65,000 km) in northern Saudi Arabia and Al-Dahna (45,000 km) in central Saudi Arabia. Both these sandy deserts ...

Lionfish are carnivorous marine fish known for their venomous spines . They are native to the warm waters of the Indo-Pacific region. However, they have now spread to tropical waters in several parts of the world. Scorpionfish is the closest living relative of lionfish, while both fish belong to the same family. This fish family ( Scorpaenidae ) includes many venomous fish species. Lionfish inhabit almost all marine habitats in their range, including coral reefs, rock bottom, seagrasses, mangroves, and even artificial reefs (shipwrecks). They live in shallow waters from 1 to 300 feet deep. The most prominent feature of a lionfish is its venomous spines . Most lionfish species have 18 spines, located on their dorsal, anal, and pelvic fins. The main purpose of these spines is defense against predators, while the fish uses its pectoral fins and large mouth to hunt prey. The venom in lionfish spines is a neuromuscular toxin . However, it is not fatal to healthy humans, and there are no ...

Assassin bugs are true bugs with more than 7,000 species . All these species are carnivores that feed on insects and other small animals. The most famous assassin bugs are kissing bugs, wheel bugs, bee assassins, three-legged bugs, feather-legged bugs, and masked hunters.  Assassin bugs use various hunting techniques to capture their prey, while different species may develop specific strategies. However, the most common hunting method is acting as ambush predators . Assassin bugs usually wait for their prey and strike with lightning speed when an insect comes within reach. An assassin bug species specializes in hunting stingless bees by manipulating their defenses , which increases its hunting success rate. Stingless bees use sticky resins around their nests as protection against predators. However, the assassin bug deliberately coats its legs with the resin to lure bees to its striking range. The success rate of this method is 75% compared to less than 30% in bugs that don’t use ...

Mantis shrimp are marine crustaceans that primarily reside in the warm, shallow waters of the Indian and Pacific oceans. However, some species may live in sub-Antarctic waters.  The name "mantis shrimp" is a misnomer, as it is neither a shrimp nor a praying mantis. This name is due to the mantis shrimp's resemblance to both these animals. The mantis shrimp is a stomatopod, whose closest living relatives are crabs , lobsters, and true shrimp. There are over 400 known mantis shrimp species . The size of these species varies, ranging from tiny animals of nearly 2.5 cm (1 inch) in length to zebra mantis shrimp reaching around 38 cm (15 inches). Zebra mantis shrimp are the largest among mantis shrimp Mantis shrimp are divided into two groups depending on their hunting techniques. The “smashers” use their club-like front legs to smash hard shells of their prey. The “spearers”, on the other hand, have spiny claws to kill soft-bodied animals . Peacock mantis shrimp, belonging t...

Clownfish are marine fish, present in the Indo-Pacific region. These reef fish are known for their bright colors, white stripes, and association with sea anemones. Clownfish are among the few animals that can change sex after birth . Every clownfish in a group is born male. In every group, the largest and most dominant fish becomes female, while the next biggest male becomes her breeding partner. If the female clownfish in a group dies or is removed, her partner becomes female. Afterwards, the next largest fish takes the role of a dominant male fish, and this cycle continues. Various clownfish species differ in their colors and number of white stripes . These fish naturally have orange, yellow, brown, or black skin colors, while the number of stripes is from zero to three. The red saddleback clownfish is famous for having no stripes during adulthood. Common clownfish, depicted in the animated film “Finding Nemo,” have three white stripes. ( Source ) Adult red saddleback clownfish are ...

Pallas’s cat, also known as manul, is a small wildcat native to the steppes and grasslands of Central Asia and its surrounding areas. Mongolia and Russia have the highest population of Pallas’s cats. The range of these wildcats is from China and Mongolia in the east to Iran in the west. The IUCN status of Pallas’s cat is “ Near Threatened .” These cats have become extinct in Azerbaijan and Armenia . Additionally, they are endangered or near threatened in countries like China, Turkmenistan, Pakistan, Mongolia, and Kyrgyzstan. The main reason behind their declining population is hunting due to the cat’s skin, fat, meat, and organs. ( Source ) Pallas’s cat has thick and long fur that protects its body from freezing conditions of its native steppe and grassland region. The dense fur also makes the cat look bigger than its actual size. Apart from the fur, its snowshoe-like paws and thick tail also assists the cat to withstand the freezing mountain climates. Pallas’s cat is named after ...
