Tsikovoka

Ny **tsikovoka** dia bibikely mamorona ny fianakaviana ***Dytiscidae***, karazana voangory (Coleoptera) anaty rano izay misy karazana efa ho 4&nbsp;000 fantatra maneran-tany. Hita any amin' ny kôntinanta rehetra izy ireo, any amin' ny faritra rehetra afa-tsy amin' ny faritra maina be. Ny ankamaroan' izy ireo dia mpiremby an-dranomamy. Mihinana azy ireo ny olona any amin' ny firenena sasany toa an' i Sina, i Vietnamy, ary i Meksika. Ny karazana tsikovoka lehibe indrindra dia ny *Dytiscus latissimus*, izay mety hahatratra 44 mm ny halavany, fa ny kely indrindra kosa dia manakaiky ny 1,5 mm. Ny karazana sasany dia atahorana ho lany tamingana, fa ny hafa kosa mbola mahazatra.

## Ohabolana

* Aza fatra-pitia tsikovoka, fandrao manenji-boantay.
* Aza mikoba-drano marivo, ka mahavery fanahy ny tsikovoka.
* Mainty ambonin' ny rano toa tsikovoka.
* Tsy misy manga noho ny voantay, fa ratsy mpilaza ka tsy nisain' ny olona ho tsikovoka.
* Toy ny tsikovova: raha manidina toa voromanga; raha mipetraka toa tavilotra.
* Tsikovoka an-dobo: matavy tsy afahy; tsindrahaka an-tatatra, mahia tsy marary.
* Tsikovoka sy fandiorano: rano no iraisana, fa ny fomba samy manana ny azy.
