During filter-feeding, the umbrella of the species continuously pulses, bringing water into the individual's mouth (Boero et al. Crinoid stalks and blastoid heads are common fossils in certain parts of North America. Most annelids use a pharynx. Under optimal conditions, bivalves tend to filter the ambient water at a maximum rate but under suboptimal environmental conditions, including low or very high algal concentrations, the filtration rate is reduced. Filter feeding is a foraging strategy that allows individuals to capture and process large quantities of prey in single mouth full, thus allowing them to acquire energy at high rates when small prey are aggregated. Despite its five meters length, the megamouth shark (Megachasma pelagios Taylor, Compagno & Struhsaker, 1983) is one of the rarest big sharks known in the world (117 specimens observed and documented so far). Some zoologists work at zoos, participating in the direct care of animals. There are some species however, ... Lambis lambis is a herbivore, but this does not mean it is not guided towards food by what we would know as smells. 5.)
