Caption: Obelia hydrozoan. Light micrograph of part of a hydroid colony of Obelia geniculata polyps. The branches of the stem give rise to either feeding polyps (hydranths, smaller structures) surrounded by a cup (hydrotheca) or reproductive polyps (larger structures) in a closed flask (gonotheca). The feeding polyps have tentacles with stinging cells (nematocysts) that inject poison into prey. The reproductive polyps bud off circular medusae (young polyps), which are either male or female. The mature medusae are then liberated into the sea. Magnification: x36 when printed at 10 centimetres high.
