Food
The tripod fish uses tactile and mechanosensory cues to identify food; the tripod fish apparently does not have special visual adaptations to help them find food in their low-light environment. When the fish is perched with its long rays on the ocean floor, it can get dinner without even seeing its meal. The tripod fish’s mouth ends up at just the right height to catch shrimp, tiny fish, and small crustaceans swimming by. They seem to prefer to perch on the mud using much elongated fin rays in their tails and two pelvic fins in order to stand, facing upstream into the current to ambush with the pectoral fins turned forward so that the outthrust projecting fins resemble multiple antennae. The fish senses objects in the water with its front fins. These fins act like hands. Once they feel prey and realize it is edible, the fins knock the food into the fish’s mouth. The fish faces into the current, waiting for prey to drift by.

Famous quotes containing the word food:
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
“... the more we recruit from immigrants who bring no personal traditions with them, the more America is going to ignore the things of the spirit. No one whose consuming desire is either for food or for motor-cars is going to care about culture, or even know what it is.”
—Katharine Fullerton Gerould (1879–1944)
“I really don’t think this war will end soon. We are completely aware of the difficulties, no food or fuel, the danger, but we want to be stronger than all that. With each child, we are fighting back with our love of life.”
—Tina Bajraktarebic (b. 1965)
