[Note Guidelines] Photographer's Note
Crocodilus niloticus chamses, the West African Nile Crocodile, is found in freshwater habitats of Senegal in a few isolated populations.

NAME ETYMOLOGY:
Crocodylus is derived from the Greek krokodeilos which means literally "pebble worm" (kroko = pebble; deilos = worm, or man) referring to the appearance of a crocodile.
Niloticus means "of the Nile" (Nile River, Africa)

SUBSPECIES:
Given the wide distribution range, a number of population differences have been observed, and several subspecies proposed. These are rarely differentiated in the literature, however, and they are not officially recognised.

Suggested subspecies: C. n. africanus (East African Nile crocodile), C. n. chamses (West African Nile crocodile), C. n. corviei (South African Nile crocodile), C. n. madagascariensis (Malagasy Nile crocodile, Malagasy alligator, Croco Mada), C. n. niloticus (Ethiopian Nile crocodile), C. n. pauciscutatus (Kenyan Nile crocodile, Kenya alligator, Kenya caiman), C. n. suchus (Central African Nile crocodile)

HABITAT:
Wide habitat preferences, reflecting their success and distribution- e.g. lakes, rivers, freshwater swamps, brackish water. Sub-adults disperse into different habitats, away from breeding areas, when they reach a length of approximately 1.2 m. Nile crocodiles modify their habitat by digging dens (usually with their snouts and feet) into which they retreat from adverse conditions such as temperature extremes.

APPEARANCE:
Considerable variation exists throughout the range of the Nile crocodile. Generally, it is a large crocodilian, averaging 5 m in length but reportedly reaching 6 m in rare instances. There is some evidence that Nile crocodiles in cooler countries (eg. South Africa) reach slightly smaller adult sizes (4 m). There are two known population of dwarf Nile crocodiles living on the extreme limits of the species' range, in Mali and even the Sahara Desert! Due to suboptimal conditions, adults average between 2 and 3 metres. Juveniles are dark olive brown with black cross-banding on the tail and body. This banding becomes fainter in adults. Total no. of teeth = 64-68.

DIET:
Although the juveniles are generally restricted to eating small aquatic invertebrates and insects, they soon move onto larger vertebrates (fish, amphibians and reptiles). Adults, however, can potentially take a wide range of large vertebrates, including antelope, buffalo, young hippos, and large cats. Fish and smaller vertebrates often form the greatest part of their diet, however. As with C. porosus, they have a reputation as being man-eaters, although probably kill more people than all other crocodilian species combined. Along with hippos and lions, crocodiles account for perhaps a few hundred deaths and disappearances each year, although exact figures are very hard to verify. Nile crocodiles will also often scavenge from carcasses, together with a number of other animals, all of which seem to tolerate each others' presence. They have a rather well-known relationship with several species of birds (e.g. spur-wing plover, called "trochilus" by Herodotus) which are reputed to pick pieces of meat from between the teeth of the crocodiles as they gape - the birds gain a meal, the crocodiles have their teeth cleaned of scraps they could not eat themselves.

BREEDING:
This species digs hole nests up to 50cm deep in sandy banks, several metres from the water. These may be in close proximity to other nests. Timing of nesting behaviour varies with geographic location - it takes place during the dry season in the north, but at the start of the rainy season further south, usually from November through to the end of December. Females reach sexual maturity around 2.6 m, males at around 3.1 m. Females lay around 40 to 60 eggs in the nest, although this number is quite variable between different populations. Females remain near the nest at all times. Incubation time averages 80 to 90 days (ranges from 70 to 100 days), after which females open the nest and carry the juveniles to the water. Both males and females have been reported to assist hatching by gently cracking open eggs between their tongue and upper palate. Hatchlings remain close to the juveniles for up to two years after hatching, often forming a creche with other females. As with many crocodilians, older juveniles tend to stay away from older, more territorial animals.

Hello Peter,
obviously, the dragonfly is not a prey for the crocodile. But what about you - just in front of it ?-)
The presented picture is proof that you captured the crocodile and not vice-versa.
What was the distance - from eye to eye?
Best wishes, Peter

Bonjour Peter,
La masse du sujet est amplifiée par l'utilisation du téléobjectif mais la valorisation est tout de même intéressante sous une bonne profondeur de champ et une belle lumière.
A bientôt sur TN pour de nouvelles aventures.

Bonjour Peter,

Hello Peter,
If it wasn't for your title I doubt if I would have even noticed the little hitchhiker on his back. What an awesome looking creature. I'm sure thankful we don't have these guys in the waterways of Ohio.
Attractive low POV and showing excellent detail. Wonderful coloration and nice DOF.
Ron

Impressive and somewhat funny scene Peter! Beautiful photo.

Hello Peter,
How funny this picture and you have well chosen the title for it. The crocodile looks really defeated..and you give us the explanation. But I like the idea of the strong dragonfly too:-) Well shown this frontal view. Original shot presented in a very natural manner.
Kind regards
Anne

Hello friend Peter,

Thank you for sharing
Hello Vanni

Great scott! Supernatural Peter. This id a classic if ever there was one. I wonder if the crock even felt it. One mistaken swift tail move could take it out!
Bob

Hi Peter, Waoow what a scary situation Hoooo:) very nice capture here my friend Peter, superb sharpness with fine detail, splendid lighting control under the harsh available light, good effort here my friend and very well done,
Best Regards,

Hallo Peter
What an interesting posting, and not one I am used to from your lens. I had to really look closely to find that dragonfly, but once found I cannot believe I did not see it. You have captured superb details here. I like the different that usual point of view, as it is not everyday we see one of these from this angle. Thanks for sharing, and also thanks for interesting reading material. Best regards.

Hello Peter,

Ha-ha, most likely they are old friends. The croc is posed nicely & even appears in deep thought. I like the low POV that shows us well the texture of this creature's form. Beautiful earthy colors as well. Great stuff!

Regards,

Derek
