In this state, they can go without food or water for several years. [3] Further, in that state they become highly resistant to environmental stresses , including temperatures from as low as −272 °C (−458 °F) to as much as +149 °C (300 °F) (at least for short periods of time [ 13 ] ), lack of oxygen , [ 3 ] vacuum , [ 3 ] ionising ...
Like other hydrozoans, some siphonophores emit light to attract and attack prey. While many sea animals produce blue and green bioluminescence , a siphonophore in the genus Erenna was only the second life form found to produce a red light (the first one being the scaleless dragonfish Chirostomias pliopterus ).

Like mayflies, stoneflies and dragonflies, but to a somewhat lesser extent, caddisflies are an indicator of good water quality; they die out of streams with polluted waters. [17] They are an important part of the food web, both larvae and adults being eaten by many fish. The newly hatched adult is particularly vulnerable as it struggles to the ...
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]
The typical ocean forage fish feed at the lower trophic level of the food chain, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers.
Okay, technically it's not a food comparison, but it's still uncomfortable to imagine mopping your floors with a living creature. 8. Labradoodle or fried chicken:
