# Hydra

Hydra vulgaris

Kiumbe mdogo wa maji baridi wa kundi la cnidaria. Anadhibitiwa na mtandao wa neva uliotawanyika na hana ubongo.

Niuroni

takriban 3,000 hadi 5,000 makadirio  · mtandao mzima wa neva; hakuna idadi kamili

## Ushahidi

* Tabia yake (kujikunja, kula, kupinduka) huendeshwa na mtandao wa neva usio na ubongo. Upigaji picha wa kalsiamu wa mnyama mzima umechora makundi yake ya niuroni.
