Dear stu­dents, to­day we are go­ing to dis­cuss about the phe­nom­e­non called Cam­ou­flage. Do you know what it is? Ro­han: I think it’s some­thing re­lated to cer­tain an­i­mals. Teacher: That’s right. It’s na­ture’s gift to cer­tain an­i­mals to pro­tect them­selves. Seema: Madam, I didn’t get it. Would you ex­plain a lit­tle more? Teacher: Of course, Cam­ou­flage is the use of any com­bi­na­tion of ma­te­ri­als, col­oration or il­lu­mi­na­tion for con­ceal­ment. This is done ei­ther by mak­ing an­i­mals or ob­jects hard to see or by dis­guis­ing them as some­thing else. Can you give an ex­am­ple? An­war: Yes Madam, Chameleon. Teacher: Ab­so­lutely right. The most common ex­am­ple is Chameleon. It can change its skin colour us­ing spe­cialised cells - Chro­matophores to re­sem­ble it’s back­ground. But re­mem­ber, there are many an­i­mals us­ing cam­ou­flage in var­i­ous ways. Cer­tain fish and frogs change colour by mov­ing pig­ment­con­tain­ing bod­ies. Fathima: I’ve watched a pro­gram on An­i­mal Planet about cer­tain an­i­mals hav­ing dis­rup­tive pat­tern such as con­trast­ing or non-repet­i­tive spots/ stripes. Teacher: Yes, the dis­rup­tive pat­terns helps to de­feat visual sys­tems. Preda­tors like the leopard use dis­rup­tive cam­ou­flage to help them ap­proach
