Doctor Plover!





Symbiosis- a relationship in which both partners benefit from each other. One such example is that of the Nile Crocodile and the Egyptian Plover. The croc opens its mouth wide to let the plover in. the plover gets a free meal by cleaning the croc’s teeth clear of food debris, and in turn doesn’t get eaten.

Safety in numbers




safety in numbers is a protective measure adopted by many animals for surviving in the harsh natural world. it is best seen in herds of herbivores such as deer and antelope. these creatures feed and roam about in large herds, and when one eats, the other is vigilant about predators. this phenomenon also helps the animals to trick predators, as choosing a specific target from a large herd often becomes very difficult.

Desperate Measures-2



a vulture using a lab rat to check if the carcass contains diclofenac :)

[diclofenac is an anti-inflammatory drug used to treat cattle ( also used as NSAID for humans as diclofenac sodium). this drug has been responsible for mass deaths of Gyps vultures throughout south Asia. vultures that feed on cattle carcasses containing diclofenac (also ketoprofen) suffer from gout and subsequent kidney failure. from 1993 to 2003, diclofenace wiped out vulture populations by almost 99percent, endangering several species that were earlier our most common vultures such as the white-backed and the long-billed vultures. veterinary diclofenac is now banned, and an alternative to it, meloxicam has been made available. but diclofenac is still being used illegally as it is cheaper than its substitute, and the threat to our vultures' existence still persists.
