They swim alone or in very loose aggregations, separated by as much as 10 m (35 ft) from a neighboring swordfish. They are frequently found basking at the surface, airing their first dorsal fin. Boaters report this to be a beautiful sight, as is the powerful jumping for which the species is known.
The sea butterflies form the sole food source of their relatives, the Gymnosomata. [8] They are also consumed by sea birds, whales, and commercially important fish. However, if sea butterflies are consumed in large quantities fish can get "black gut", which makes them unsellable. [1]
Additional plants which will provide for the needs of caterpillars and butterflies are: shasta daisy, black-eyed Susan, cardinal flower, phlox, cosmos, sedums, ironweed, mountain laurel, verbena ...
If this is a problem with dolphins it is an even greater problem with billfish such as swordfish, which swim and accelerate faster than dolphins. In 2009, Taiwanese researchers from the National Chung Hsing University introduced new concepts of "kidnapped airfoils and circulating horsepower" to explain the swimming capabilities of swordfish.
A school of false Moorish idols, Heniochus diphreutes. Butterflyfish mostly range from 12 to 22 cm (4.7 to 8.7 in) in length. The largest species, the lined butterflyfish and the saddle butterflyfish, C. ephippium, grow to 30 cm (12 in).
Sailfish were previously estimated to reach maximum swimming speeds of 35 m/s (125 km/h), but research published in 2015 and 2016 indicate sailfish do not exceed speeds between 10–15 m/s (35–55 km/h). During predator–prey interactions, sailfish reached burst speeds of 7 m/s (25 km/h) and did not surpass 10 m/s (35 km/h).
This is about twice as fast as their prey, the sea butterfly. Tracing the wingtip showed a ‘figure-of-eight’ trajectory and stroke plane orthogonal to the caudal-rostral axis, this pattern was observed in some aerial insects, small birds, and sea butterflies such as hummingbirds and Limacina helicina.
