Trbušne ljuske su izraženo grebenaste. Prednji dio tijela je obično sivo zelen ili maslinasto smeđ, čestoprema repu postaje sve smeđije ilicrvenkastije. Red velikih crnih ili maslinastih pjegana bočnim stranama vrata, od kojih svaka može biti okružena koncentričnim tamnim i vanjskim svijetlim prstenovima. Te pjege su izraženije i protežu se dulje po tijelu kod mladih jedinki. Koža ispred i iza oka svijetlo obojana. Trbuh je žut ili bijelkast, bez pjega. Glatke ljuske na leđima.

Description:
Adults up to 135 cm, but usually under 100 cm. Easily identified by build and pattern. A very slender snake with a narrow and well defined head and a tail that is 1/4 or even 1/3 of qhole body length. Belly scales are distinctly keeled. Foreparts are usually green or olive brown, often becoming towards tail more brownish or even reddish. A row of big black or olive spots on sides of neck, each of which can be surrounded by concentric dark and outer light rings. Those spots are more prominent and extend further down the body in young animals. Skin in front and behind the eye is light coloured. Belly is yellow or whiteish, without spots. Back scales are smooth.

WHERE:

The whole Adriatic coast, N to Crikvenica, some islands (Krk, Pag...)

Br. ljusaka:
19 (rijetko 17) preko sredine leđa, oko 205-223 trbušnih, 104-138 parova podrepnih.
Scale Count:
19 (rarely 17) dorsals across body, 205-223 belly scales, 104-138 pairs of subcaudals.
Stanište:
Voli suha, često kamenita staništa, ponekad s grmljem i nešto guste vegetacije po kojoj se penje. Pojavljuje se na čistinama, u šumama, kraj obraslih zidova, kamenitim obalama, kamenitim kotlinama, ruševinama, rubovima puteva...
Habitat:
Likes dry, often rocky habitats, sometimes with bushes and somedense vegetation in which it climbs. Occurs in open  areas, in woods, by overgrown walls, stony banks, boulder-choked gullies., ruins, path edges...
Ponašanje:
Aktivan danju i pretežito prizemna vrsta, voli suha, često kamenita staništa, ponekad s grmljem i nešto guste vegetacije po kojoj se penje. Pojavljuje se na čistinama, u šumama, kraj obraslih zidova, kamenitim obalama, kamenitim kotlinama, ruševinama, rubovima puteva... Vrlo brza u usporedbi s ostalim poljaricama. Ponekad grize kad ga se primi. Za razliku od većine zmija, ne sikće.
Behaviour:
Diurnal and a mainly terestrial species, likes dry, often rocky habitats, sometimes with bushes and somedense vegetation in which it climbs. Occurs in open  areas, in woods, by overgrown walls, stony banks, boulder-choked gullies., ruins, path edges... A very fast snakee, in comparison to other Whip Snakes. Sometimes bites when handled. Unlike most other snakes, it does not hiss.
Prehrana:
Plijen lovi brzinom i znade ga proganjati na veće udaljenosti (za zmiju). Manji plijen jednostavno primi ustima i počne gutati, dok veće nekad pritisne o tlo s tijelom ili ih 2-3 puta omota tijelom dok ih guta. Pretežito se hrani malim gušterima, skinkovima, čak i malim agamama. Također se hrani skakavcima, drugim beskralježnjacima, rijeđe malim sisavcima. Slina ima toksičnih svojstava i plijen ugine vrlo brzo (ali to je BEZOPASNO za ljude).
Food:
Runs down prey by speed and sometimes pursues it for considerable distances (for a snake). Smaller prey is grabbed in the jaws and swallowed, while larger prey is sometimes pressed against the ground or wraped 2-3 times while swallowing. Feeds mainly on small lizards, especially lacertids, skinks, even small agamas. Also feeds on grasshoppers and other invertebrates, rarely small mammals. Saliva has toxic propeties so prey dies very quickly (but that is HARMLESS to humans).
Razmnožavanje:
Ženke polažu 3-16 vrlo izduženih jaja (21-44mm x 5-14mm), iz kojih se izlegnu mladi manji od 30 cm.
Reproduction:
Females lay 3-16 very elongated eggs (21-44mm x 5-14mm), producing hatchlings less than 30 cm long.
