Glochidia look like tiny mussels, and they are parasites that must attach themselves to the fins or gills of a fish. The fertilized eggs are brooded in the female's gills, where they develop into tiny larvae called glochidia. When buying mussels, the shells should be bright, undamaged and closed. Zebra mussels feed by filtering the water to collect phytoplankton while clinging to the substrate. Mussel culture is usually based on collection of natural seed. Hydrothermal vents are places where seawater exits cracks in the sea floor, having been super-heated and enriched with metals and minerals deep in the underlying bedrock. Some mussels simply release glochidia into the water where they must haphazardly come into contact with the appropriate fish host as it swims by. Life history cycle. Threatened and endangered land snails. Only strong predators able to break hard shells consume Blue Mussels, including large starfish, crustaceans, and some birds (Newell, 1989). In the wild, they can live for several years and grow to 20 cm or more (shell length) but most have become reproductively active by the time they reach 4-5 cm.
