Basic needs of animals for survival (food, water, air) Key Terms: Hatchlings: Baby crocodiles and alligators Juveniles: Young crocodiles and alligators Adults: Older crocodiles and alligators Hatch: when baby crocodiles first come out of their egg Mature: When a crocodile is old enough to reproduce. Eggs: This is an egg from a saltwater crocodile. Crocodiles and alligators hatch from EGGS A 10p coin is there for size comparison Nests: Parents The eggs are laid in NESTS. Some nest NEST are mounds of grasses and other vegetation; some are holes dug into the sandy river bank. NEST The mother crocodile will guard the nest She will even help the baby crocodiles into the water for the first time. Even though they spend a lot of time in the water, they need to breathe air like we do. But they will drink whilst they are in the water. It can take 15 years for a baby crocodile to mature. When crocodiles are fully grown, they may be 10,000 times heavier than they were when they hatched! This image shows a baby alligator on the head of its father. Number these pictures from 1 to 4, placing them in order from youngest to oldest: Collecting Eggs from crocodiles We collect the eggs from the crocodiles once the eggs are laid. This is so we can control how many baby crocodiles hatch out. Otherwise, we might end up with too many baby crocs. When we collect the eggs, the mother and father crocodile will try to protect the eggs. Crocodiles are very good parents, and will defend their babies for about 6 or 8 months! That means, it is a little bit dangerous when we do collect those eggs! When a crocodile is very young, it eats things like insects and small frogs and fish. They are too small to eat anything larger than this. However, other animals, including birds, fish, turtles and lizards, will eat baby crocodiles! As they grow, crocodiles eat larger and larger animals. The biggest crocodiles can eat most animals that come down near the water. Because crocodiles eat meat, they are called C_ _ _ _ V _ _ _ _ . .

Nile Crocodile Fact Sheet 2017
NILE CROCODILE FACT SHEET 2017 Common Name: Nile crocodile Order: Crocodylia Family: Crocodylidae Genus & Species: Crocodylus niloticus Status: IUCN Least Concern; CITES Appendix I and II depending on country Range: The Nile crocodile is found along the Nile River Valley in Egypt and Sudan and distributed throughout most of sub-Saharan Africa and Madagascar. Habitat: Nile crocodiles occupy a variety of aquatic habitats including large freshwater lakes, rivers, freshwater swamps, coastal estuaries, and mangrove swamps. In Gorongosa, Lake Urema and its network of rivers are home to a large crocodile population. Description: Crocodylus niloticus means "pebble worm of the Nile” referring to the long, bumpy appearance of a crocodile. Juvenile Nile crocodiles tend to be darker green to dark olive-brown in color, with blackish cross-banding on the body and tail. As they age, the banding fades. As adults, Nile crocodiles are a grey-olive color with a yellow belly. Their build is adapted for life in the water, having a streamlined body with a long, powerful tail, webbed hind feet and a long, narrow jaw. The eyes, ears, and nostrils are located on the top of the head so that they can submerge themselves under water, but still have sensing acuity when hunting. Crocodiles do not have lips to keep water out of their mouth, but rather a palatal valve at the back of their throat to prevent water from being swallowed. Nile crocodiles also have integumentary sense organs which appear as small pits all over their body. Organs located around the head help detect prey, while those located in other areas of the body may help detect changes in pressure or salinity.

Crocodile Facts and Figures
Crocodile facts The saltwater crocodile is the largest living reptile species. It can grow up to six metres and is a serious threat to humans. Saltwater crocodiles have evolved special characteristics that make them excellent predators. • Large saltwater crocodiles can stay underwater for at least one hour because they can reduce their heart rate to 2-3 beats per minute. This means that crocodiles can wait underwater until they see prey, or if people are using the same spot regularly, the crocodile can wait underwater until someone approaches the water’s edge. • A crocodile can float with only eyes and nostrils exposed, enabling it to approach prey without being detected. • When under water, a special transparent eyelid protects the crocodile’s eye. This means that crocodiles can still see when they are completely submerged. • The tail of a crocodile is solid muscle and a major source of power, making it a strong swimmer and able to make sudden lunges out of the water to capture prey. These strong muscles also mean that for shorts bursts of time crocodiles can move faster than humans can on land. • Crocodiles have a thin layer of guanine crystals behind their retina. This intensifies images, allowing crocodiles to see better at low light levels. • Crocodiles have a ‘minimum exposure’ posture in the water, which means that only their sensory organs of eyes, cranial platform, ears and nostrils remain out of the water. This means that they often go unseen by prey, but if they are observed, the prey is often not able to tell how big the crocodile is.

Fascinating Folktales of Thailand
1. The rabbiT and The crocodile Once upon a time the rabbit used to have a long and beautiful tail similar to that of the squirrel and at that time the crocodile also had a long tongue like other animals on earth. Unfortunately, one day while the rabbit was drinking water at the bank of a river without realizing possible danger, a big crocodile slowly and quietly moved in. It came close to the poor rabbit. The crocodile suddenly snatched the small creature into its mouth with intention of eating it slowly. However, before swallowing its prey, the crocodile threatened the helpless rabbit by making a loud noise without opening its mouth. Afraid as it was, the rabbit pretended not to fear approaching death and shouted loudly. “A poor crocodile! Though you are big, I’m not afraid of you in the least. You threatened me with a noise not loud enough to make me scared because you didn’t open your mouth widely.” Not knowing the rabbit’s trick, the furious crocodile opened its mouth widely and made a loud noise. As soon as the crocodile opened its mouth, the rabbit jumped out fast and its sharp claws snatched away the crocodile’s tongue. At the moment of sharp pain, the crocodile shut its mouth at once as instinct had taught it to do. At the end of the episode, the rabbit lost its beautiful tail while the crocodile lost its long tongue in exchange for its ignorance of the trick. From then on, the rabbit no longer had a long tail while the crocodile no longer had a long tongue as other animals.

Crocodile Birds Bats Elephant
1 Bats Let’s take a close look at bats. They have plenty of special features, but the easiest to see are the wings! Bats are great flyers that use their flying skills to catch insects. You might know about a group of prehistoric creatures that were also amazing flyers--pterosaurs! Pterosaurs were flying reptiles that lived in the Mesozoic Era, the Age of Dinosaurs, but they aren’t dinosaurs themselves. The most famous pterosaurs are pteranodons, like Tiny, Shiny, and Don! But pterosaurs came in a lot of different sizes, from tiny bat-like Peteinosaurus to giant, airplane-sized Quetzalcoatlus! The biggest pterosaur, Quetzalcoatlus, had a wingspan—the distance from one wingtip to the other—of about 40 feet, around the same length as a T. rex! How big is your wingspan? Stretch out your arms and measure from the tip of one hand to the tip of the other! Birds Great job! You’ve found the dinosaurs! I mean, the birds! Well, actually, they’re both. You see, all living birds are the direct descendents of theropod dinosaurs that lived long ago in the Jurassic time period! And that means birds are really living dinosaurs! Because birds are such close cousins of ancient raptors like Velociraptor, these animals share a lot in common, including feathers, hollow bones, and three-toed feet! So the next time you go bird watching you’ll really be dinosaur watching! Pay attention today, how many birds will you see? Try and count them! Crocodile Let’s look closely at the crocodiles. What does their skin look like? Crocodiles have thick, scaly skin for protection.

Email: adriankelly1000@yahoo. co.uk ABSTRACT African Nile crocodiles are the only species of crocodile consistently found across central and sub-Saharan Africa. A large and specifically aggressive species of the African Nile crocodile is solely responsible for almost all unprovoked attacks on humans, the exact incidence of which is unknown. The reported mortality rate of an African Nile crocodile attack is between 65-91% with up to 70% of surviving individuals with a bite of a limb ultimately requiring amputation. We describe an adult male patient whom, during the course of performing his daily duties, slipped on a riverbank and fell into the water where he was immediately seized on the left forearm by an African Nile crocodile. Through fighting back the African Nile crocodile released its hold and he was able to survive the attack and reach our unit. Despite relatively benign looking wounds the initial surgical exploration revealed the true extent of the underlying muscle damage and within hours a flexor compartment syndrome developed needing surgical management.
