Digestive system of humpback whales stretching like an accordion. They allow whales to open their mandible to 90 degrees to gulp water and prey. They expel saltwater through the baleen plates, leaving behind krill and plankton. The whale's tongue plays a vital role in filter feeding, as it is used to push the water out of its mouth while keeping the prey trapped in its baleen bristles. As humpback whales do not have teeth, their food is swallowed whole and travels down the esophagus into the preliminary stomach (known as the forestomach) to be ground. Baleen whales have a multi-chambered stomach, divided into three distinct
Greater white-toothed shrew and migration to empty breeding sites. Nonetheless, this dispersal pattern is a preventative measure for inbreeding. The greater white-toothed shrew can be very vocal."C. russula" can find their way around their environment via a primitive form of echolocation where they produce a high pitched twittering call to interpret their environment. The use of this laryngeal call and vibrissae allow the shrews to find their way around their environment. There have not been any concrete reports on the modes of communication used by this species,however, the vocalization and tactile and chemical cues likely to be used. The greater white-toothed shrew typically
