1. Kj\u00f8ttetere:<\/strong>\u00a0Rovdyr er dyr som lever av \u00e5 spise andre dyr. Rovdyr er kj\u00f8ttetere, noe som betyr at de hovedsakelig lever av kj\u00f8tt.<\/p>\n

2. \u00c5tseletere:<\/strong>\u00a0Noen rovdyr jakter p\u00e5 byttet sitt, mens andre er \u00e5tseletere og spiser rester av andre rovdyrs byttedyr eller d\u00f8de dyr.<\/p>\n

3. Byttedyr:<\/strong>\u00a0I motsetning til rovdyr finnes det byttedyr som kan v\u00e6re b\u00e5de kj\u00f8ttetere og planteetere. Dyr som kan spise b\u00e5de kj\u00f8tt og planter, kalles \"omnivore\" eller \"altetende\" dyr.<\/p>\n

4. Dyreriket:<\/strong>\u00a0Selv om ordet \"rovdyr\" gir assosiasjoner til dyr med spisse tenner og skarpe kl\u00f8r, er det ikke alle rovdyr som har disse egenskapene. Som nevnt er rovdyr alle dyr som spiser andre dyr for \u00e5 overleve, og de finnes i alle deler av dyreriket - inkludert am\u00f8ber, nematoder, bl\u00f8tdyr, leddyr og leddormer, fisk<\/a>, amfibier og reptiler, Fugler<\/a> og pattedyr<\/p>\n

5. N\u00e6ringskjeden:<\/strong>\u00a0N\u00e6ringskjeden er en prosess der energi overf\u00f8res fra en organisme til den neste. Rovdyr er en viktig del av n\u00e6ringskjeden og er vanligvis involvert p\u00e5 f\u00f8lgende m\u00e5te: 1) en plante absorberer solens energi 2) en planteeter spiser planten 3) et rovdyr spiser planteeteren 4) en alteter spiser rovdyret og er dermed \u00f8verst i n\u00e6ringskjeden<\/p>\n

\"Fakta:
Navngivelse: Rathika Ramasamy + Daniel Flower + Kieran (AU) - Flickr.com<\/figcaption><\/figure>\n

Fakta: Rovdyr omfatter alle dyr som lever av \u00e5 spise kj\u00f8tt. Rovdyr finnes derfor i alle deler av dyreriket.<\/strong><\/em><\/p>\n

6. Jaktteknikker:<\/strong>\u00a0Hvordan et rovdyr jakter p\u00e5 og tar byttet sitt avhenger av flere faktorer, men som oftest brukes \u00e9n av f\u00f8lgende fire teknikker: jakt, forf\u00f8lgelse, bakhold eller samarbeid.<\/p>\n

7. Hjelpemidler:<\/strong>\u00a0De mest \u00e5penbare jakthjelpemidlene er tenner og kl\u00f8r, men utmattelse, gift og elektrisitet brukes ogs\u00e5 (som i ulver<\/a>, slanger<\/a> og elektrisk \u00e5l<\/a>, henholdsvis)<\/p>\n

8. Verkt\u00f8y:<\/strong>\u00a0P\u00e5 samme m\u00e5te som det finnes naturlige hjelpemidler, finnes det ogs\u00e5 ulike verkt\u00f8y som krever en viss intelligens for \u00e5 kunne brukes. Eksempler p\u00e5 dette er 1) sjimpanser som griper etter maur med pinner eller kaster spyd etter andre primater, 2) delfiner<\/a> bruker sj\u00f8svamper til \u00e5 grave opp havbunnen for \u00e5 komme til nedgravde byttedyr, eller 3) havotere knuser skjell med steiner.<\/p>\n

9. Gullsmeden:<\/strong>\u00a0\u00d8yenstikkeren regnes i dag som det mest vellykkede rovdyret n\u00e5r det gjelder jakt. En \u00f8yenstikker feller rundt 95% av alle byttedyrene den jakter p\u00e5. Til sammenligning har en l\u00f8ve en jaktsuksess p\u00e5 25% og en hai p\u00e5 50%.<\/p>\n

10. Rovdyr\/byttedyr:<\/strong>\u00a0I zoologien snakker vi om forholdet eller samspillet mellom rovdyr og byttedyr - dvs. at visse rovdyr har sine byttedyr og omvendt. Eksempler p\u00e5 dette er l\u00f8ve - sebra<\/a>bj\u00f8rn - fisk, rev - kanin osv. De to gruppene lever i samme milj\u00f8 der de utvikler seg og tilpasser seg sammen.<\/p>\n

\"\u00d8yenstikkeren

Blant alle verdens rovdyr regnes \u00f8yenstikkeren som den mest vellykkede jegeren, og den klarer \u00e5 felle byttet sitt 95% av gangene. Suksessen skyldes hovedsakelig at \u00f8yenstikkeren kan beregne byttedyrets kommende posisjon og forutse hvor den kan fange det...<\/strong><\/em><\/p>","protected":false},"excerpt":{"rendered":"
