An Anopheles stephensi mosquito obtaining a blood meal from a human host through its pointed proboscis. Note the droplet of blood being expelled from the engorged abdomen. This mosquito is a malarial vector with a distribution that ranges from Egypt to China. A bedbug Two butterflies of the genus Erebia sucking fresh blood from a sock
Predatory leeches feed on small invertebrates such as snails, earthworms and insect larvae. The prey is usually sucked in and swallowed whole. Some Rhynchobdellida however suck the soft tissues from their prey, making them intermediate between predators and blood-suckers. [38] Leech attacking a slug
The cougar (Puma concolor) (/ ˈ k uː ɡ ər /, KOO-gər), sometimes called the mountain lion, catamount, puma, or panther is a large small cat native to the Americas. It inhabits North, Central and South America, making it the most widely distributed wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread in the world.
Adult females of many species have mouthparts adapted to pierce the skin of a host and feed on blood of a wide range of vertebrate hosts, and some invertebrates, primarily other arthropods. Some species only produce eggs after a blood meal. The mosquito's saliva is transferred to the host during the bite, and can cause an itchy rash. In ...
Typically, after courtship, the male fertilises the eggs and then collects them in his mouth, holding onto them until they hatch. During this time he cannot feed. During this time he cannot feed. Among the maternal mouthbrooding cichlids, it is quite common (e.g., among the mbuna) for the male to fertilise the eggs only once they are in the ...
Oligochaetes have a sticky pad in the roof of the mouth. [8] Most are burrowers that feed on wholly or partly decomposed organic materials. [13] Hirudinea, whose name means "leech-shaped" and whose best known members are leeches. [8] Marine species are mostly blood-sucking parasites, mainly on fish, while most freshwater species are predators. [13]
The eastern cougar or eastern puma (Puma concolor couguar) is a subspecies designation proposed in 1946 for cougar populations in eastern North America. [ 2 ] [ 3 ] The subspecies as described in 1946 was declared extinct by the U.S. Fish and Wildlife Service in 2011. [ 4 ]
Chironomidae have variable feeding ecology: most species feed on algae and other small soil organisms they can filtrate. [ 22 ] [ 23 ] Some commensal species feed off of algae on their hosts, which also provides the benefit of protection and additional mobility; particularly when their chosen host site is another predatory larval species.
