Denizanas\u0131n\u0131n beyni yoktur ancak v\u00fccuduna \u00e7e\u015fitli sinyaller g\u00f6nderen n\u00f6ronlardan olu\u015fan bir a\u011f\u0131 vard\u0131r. Kalbi ve akci\u011ferleri de olmayan bu canl\u0131lar oksijeni do\u011frudan derileri yoluyla al\u0131r. Okyanus ak\u0131nt\u0131lar\u0131yla s\u00fcr\u00fcklenmenin yan\u0131 s\u0131ra, v\u00fccudundan su f\u0131\u015fk\u0131rtarak da hareket edebilir. Bu sayede plankton gibi avlar\u0131na do\u011fru yol al\u0131rken bal\u0131klar, kaplumba\u011falar ve deniz ku\u015flar\u0131 gibi y\u0131rt\u0131c\u0131lardan ka\u00e7abilir. Dokuna\u00e7lar\u0131ndaki keskin i\u011fneler, yabanc\u0131 cisimlere tepki verir ve toksin salg\u0131lar; bu toksin, istenmeyen misafirleri etkisiz h\u00e2le getirebilir veya \u00f6ld\u00fcrebilir.<\/p>\n

Midye, iki mente\u015feli kabu\u011fun aras\u0131nda korunan yumu\u015fac\u0131k bir v\u00fccuda sahip, denizlerin dayan\u0131kl\u0131 sakinlerinden biridir. Kabuklar\u0131n\u0131 a\u00e7\u0131p kapatma yetene\u011fiyle hem kendini korur hem de \u00e7evresine uyum sa\u011flar. \u0130stiridye ve deniztara\u011f\u0131 ile ayn\u0131 aileden gelir. Beyni olmasa da geli\u015fmi\u015f sinir sistemi sayesinde \u00e7evresindeki de\u011fi\u015fimlere h\u0131zla tepki verir. V\u00fccudunda b\u00f6brek, mide, a\u011f\u0131z ve atan bir kalp bulunur; bu organlar onun hayatta kalmas\u0131n\u0131 sa\u011flar. Kolay yakalanmas\u0131 ve d\u00fcnya genelinde yayg\u0131n olmas\u0131 nedeniyle bal\u0131k\u00e7\u0131l\u0131kta da olduk\u00e7a pop\u00fclerdir.<\/p>\n

Deniz anemonu, beyni olmamas\u0131na ra\u011fmen \u00e7evresine son derece duyarl\u0131 bir deniz canl\u0131s\u0131d\u0131r.

Ne kalbi vard\u0131r ne de akci\u011feri\u2026 Beyni de yoktur ama hayatta kalma stratejileri geli\u015fmi\u015ftir. Derin denizlerin sakini olan bu canl\u0131, kimi zaman 1.000 metreye kadar iner sonra y\u00fczeye d\u00f6ner ve hi\u00e7 yorulmaz. A\u011f\u0131z \u00e7evresindeki t\u00fcp ayaklar\u0131yla planktonlar\u0131, algleri ve organik at\u0131klar\u0131 s\u00fczer. Tehlike an\u0131nda baz\u0131 t\u00fcrleri holothurin adl\u0131 zehirli bir madde salg\u0131lar; \u00f6yle ki bu madde insanlarda kal\u0131c\u0131 k\u00f6rl\u00fc\u011fe bile neden olabilir.<\/p>\n
