For example, zebrafish, [7] tilapia, [8] tench, [9] brown bullhead, [10] and swell shark [11] become motionless and unresponsive at night (or by day, in the case of the swell shark); Spanish hogfish and blue-headed wrasse can even be lifted by hand all the way to the surface without evoking a response. On the other hand, sleep patterns are ...
The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
An alternative etymology is that pilot fish were once, erroneously, [29] thought to be piloting sharks to food, [30] [31] or even (as legends have it) piloting ships, whales and swimmers to safety. [32] The pilot fish is sometimes used as a metaphor or simile; "they are like the pilot fish to the shark, serving to lead him to his victim". [33]
Other species of jellyfish are among the most common and important jellyfish predators. Sea anemones may eat jellyfish that drift into their range. Other predators include tunas, sharks, swordfish, sea turtles and penguins. [84] [85] Jellyfish washed up on the beach are consumed by foxes, other terrestrial mammals and birds. [86]
In the Faroe Islands, whales mostly eat squid, but will also eat fish species such as greater argentine and blue whiting. However, Faroe whales do not seem to feed on cod, herring, or mackerel, even when they are abundant. [20] Pilot whales generally take several breaths before diving for a few minutes. Feeding dives may last over ten minutes.

[52] [53] During migration through the open sea, loggerheads eat jellyfish, floating molluscs, floating egg clusters, squid, and flying fish. [9] Loggerheads crush prey with their large and powerful jaws. [9] [54] Projecting scale points on the anterior margin of the forelimbs allow manipulation of the food. These points can be used as "pseudo ...
A larger shoal might be 7 kilometres (4.3 mi) long, 1.5 kilometres (0.93 mi) wide and 30 metres (98 ft) deep. Huge numbers of sharks, dolphins, tuna, sailfish, Cape fur seals and even killer whales congregate and follow the shoals, creating a feeding frenzy along the coastline. [46]
