Simplu: asta e un vierme acvatic, ala e mediul lui natural, de asta e si in meniul salmonidelor. Larvele lui, insa, sunt parazite, ouale lui fiind ingerate in general de orthoptere: cosasi, lacuste,etc..
Cand larvele vor sa iasa se intampla asta, cum punctam mai sus, in thread:
"In Spinochordodes tellinii and Paragordius tricuspidatus which have orthopterans as their vector, the infection acts on the insect's brain and causes it to seek water and drown itself, thus returning the nematomorph to water.[6] P. tricuspidatus is also remarkably able to survive the predation of their host, being able to wiggle out of the predator that has eaten the host.[8]"
Deci scopul larvelor e sa ajunga in apa, intr-un mod sau altul. In clip, probabil ca au simtit apa si au iesit.
