1. K\u00f8d\u00e6dere:<\/strong>\u00a0Rovdyr er dyr, der lever af at spise andre dyr. Rovdyr er k\u00f8d\u00e6dere, hvilket betyder, at deres kost prim\u00e6rt best\u00e5r af k\u00f8d.<\/p>\n

2. \u00c5dsel\u00e6dere:<\/strong>\u00a0Nogle rovdyr jager deres bytte, mens andre er \u00e5dsel\u00e6dere, der spiser resterne af andre rovdyrs bytte eller d\u00f8de dyr.<\/p>\n

3. Byttedyr:<\/strong>\u00a0I mods\u00e6tning til rovdyr findes der byttedyr, som b\u00e5de kan v\u00e6re k\u00f8d\u00e6dere og plante\u00e6dere. Dyr, der kan spise b\u00e5de k\u00f8d og planter, kaldes 'omnivore' eller 'alt\u00e6dende' dyr.<\/p>\n

4. Dyrenes rige:<\/strong>\u00a0Selvom ordet \"rovdyr\" leder tankerne hen p\u00e5 et dyr med spidse t\u00e6nder og skarpe kl\u00f8er, er det ikke alle rovdyr, der har disse egenskaber. Som n\u00e6vnt er rovdyr ethvert dyr, der spiser andre dyr for at overleve, og de kan findes i alle dele af dyreriget - inklusive am\u00f8ber, nematoder, bl\u00f8ddyr, leddyr og leddyr, fisk<\/a>amfibier, krybdyr, fugle<\/a> og pattedyr<\/p>\n

5. F\u00f8dek\u00e6den:<\/strong>\u00a0F\u00f8dek\u00e6den er en proces, hvor energi overf\u00f8res fra en organisme til den n\u00e6ste. Rovdyr er en vigtig del af f\u00f8dek\u00e6den og er typisk involveret p\u00e5 f\u00f8lgende m\u00e5de: 1) en plante absorberer solens energi 2) en plante\u00e6der spiser planten 3) et rovdyr spiser plante\u00e6deren 4) en alt\u00e6der spiser rovdyret og er dermed i toppen af f\u00f8dek\u00e6den<\/p>\n

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

Fakta: Rovdyr omfatter alle dyr, der lever af at spise k\u00f8d. Rovdyr findes derfor i alle dele af dyreriget.<\/strong><\/em><\/p>\n

6. Jagt-teknikker:<\/strong>\u00a0Hvordan et rovdyr jager og nedl\u00e6gger sit bytte, afh\u00e6nger af flere faktorer, men oftest bruges en af f\u00f8lgende fire teknikker: jagt, forf\u00f8lgelse, baghold eller samarbejde.<\/p>\n

7. Hj\u00e6lpemiddelteknologi:<\/strong>\u00a0De mest oplagte jagtredskaber er t\u00e6nder og kl\u00f8er, men udmattelse, gift og elektricitet bruges ogs\u00e5 (som i ulve<\/a>, Slanger<\/a> og elektriske \u00e5l<\/a>henholdsvis)<\/p>\n

8. V\u00e6rkt\u00f8j:<\/strong>\u00a0Ligesom der er naturlige hj\u00e6lpemidler, er der ogs\u00e5 forskellige redskaber, som kr\u00e6ver et vist niveau af intelligens at bruge. Eksempler herp\u00e5 er 1) chimpanser, der r\u00e6kker ud efter myrer med stokke eller kaster spyd efter andre primater, 2) delfiner<\/a> bruger havsvampe til at grave havbunden op for at f\u00e5 adgang til nedgravet bytte, eller 3) havoddere knuser muslingeskaller med sten.<\/p>\n

9. Guldsmeden:<\/strong>\u00a0Guldsmeden betragtes i dag som det mest succesfulde rovdyr p\u00e5 jagt, idet en guldsmed nedl\u00e6gger omkring 95% af alle byttedyr, den jager. Til sammenligning er en l\u00f8ves jagtsucces omkring 25% og en hajs omkring 50%.<\/p>\n

10. Rovdyr\/byttedyr:<\/strong>\u00a0I zoologi taler vi om forholdet eller samspillet mellem rovdyr og bytte - dvs. at visse rovdyr har deres bytte og omvendt. Eksempler inkluderer l\u00f8ve - Zebra<\/a>bj\u00f8rn - fisk, r\u00e6v - kanin osv. De to grupper lever i det samme milj\u00f8, hvor de udvikler sig og tilpasser sig sammen.<\/p>\n

\"Guldsmeden

Blandt alle verdens rovdyr betragtes guldsmeden som den mest succesfulde j\u00e6ger, der form\u00e5r at nedl\u00e6gge sit bytte 95% af gangene. Dens succes skyldes hovedsageligt, at den kan beregne sit byttes kommende position og forudsige, hvor den kan fange det...<\/strong><\/em><\/p>","protected":false},"excerpt":{"rendered":"
