The phrase "suction feed" is correct and usable in written English.
This phrase is typically used to describe a device or mechanism that works by creating a vacuum or suction to draw in and feed a material or substance. For example, "The machine uses a suction feed to bring pellets of feed into a hopper".
Nicola Hodgins, of Whale and Dolphin Conservation, added: "Although the large pieces will cause obvious problems and block the gut, we shouldn't dismiss the smaller bits that could cause a more chronic problem for all species of cetacean – not just those who suction feed".
Plagiosuchus has very small teeth and a large area for muscle attachment behind the skull, suggesting that it could suction feed by rapidly opening its mouth.
However, suction feeding is variably combined with ram-feeding modes in different cetaceans [ 18] and is employed by pinnipeds feeding on a variety of prey types [ 16, 20] suggesting that these contrasting feeding modes may not map neatly onto differences in trophic guild.
But the African tadpoles' eating behavior is similar to that of many larval fish, suggesting that suction feeding evolved independently in two families of animals.
But suction feeding doesn't come easily when fish first hatch.
But on land, thin air makes suction feeding impossible, so vertebrates need to bite to get by.
Like most fish, seahorses nab their prey by slurping in the water surrounding their victims a technique called suction feeding.
The whale's wide skull would have boosted the volume of its mouth and, in turn, the efficiency of suction feeding, he suggests.
Since the shape of the buccal cavity is a critical determinant of the suction performance, this snout allometry will inevitably affect the suction feeding ability.
Instead, Fitzgerald contends, the whale depended on suction feeding: By dropping its tongue and lower jaw, it pulled in water and slurped prey such as large fish or squid into its toothy maw.
One of the earliest close relatives of modern-day sharks, Bandringa (pictured in an artist's representation above, with its sensitive spoon-billed snout) was a bottom dweller, analogous to today's sawfish, that lived in an ancient river delta and probably fed by suction feeding, vacuuming prey directly into its downward-facing jaws.
