In the picture we see a water flea from the genus Simocephalus.
Summary[edit]
| Description |
Eesti: Simocephalus sp. on 3–4 mm pikkused vesikirbud Vesikirbulistel on (nagu ka teistel vähkidel) peas kaks paari tundlaid. Neist esimesed on väikesed, teised aga suured ja kaheharulised, mis lükkavad vähi keha ujumisel edasi. Vees on vesikirbuliste liikumine neile ainulaadselt hüppeline, millest ka nimetus "vesikirp". Pea alumisel küljel paikneb suu, mida ümbritseb eest ülahuul, tagant alalõuad ja külgedelt ülalõuad.
Antud pildil on näha vesikirbu haudetaskus püsimuna. Püsimuna moodustub vesikirpudel, siis kui elutingimused halvenevad, nt on tulemas talv Antud isend on leitud linnatiigist Rakveres.English: Simocephalus sp. are 3-4 mm in length, round animals that are covered in a bivalve carapace. The head, which contains a single compound eye, is not covered by this carapace but instead is surrounded by a hood. The given picture shows a resting egg in the hatching pocket of a water flea. Permanent eggs are formed in water fleas when living conditions deteriorate, e.g. winter is coming.
This specimen was found in a city pond in the city of Rakvere in Estonia |
