The shark has the greatest electrical sensitivity of any animal. Sharks find prey hidden in sand by detecting the electric fields they produce. Ocean currents moving in the magnetic field of the Earth also generate electric fields that sharks can use for orientation and possibly navigation. [26]
"Sharks" is a song by American pop rock band Imagine Dragons, released as the second single from the band's fifth studio album, Mercury – Acts 1 & 2 on June 24, 2022. The song was released through Interscope and Kidinakorner. It was written by Dan Reynolds, Wayne Sermon, Ben McKee, Daniel Platzman, and its producers Mattman & Robin.
Shark migration patterns may be even more complex than in birds, with many sharks covering entire ocean basins. Sharks can be highly social, remaining in large schools. Sometimes more than 100 scalloped hammerheads congregate around seamounts and islands, e.g., in the Gulf of California. [39] Cross-species social hierarchies exist.
"Sharks inhabit pretty much every ocean, every sea, every marine environment on the globe, so if you're speaking to kids, it's about them paying attention to what's happening in and around the ...
Great white sharks (Carcharodon carcharias) are the largest-known predatory fish in the ocean. Belonging to the Lamnidae family, this type of mackerel shark can grow to be up to 21 feet long and ...
Sensitivity to the earth's electromagnetic fields, or to weather pressure, can be used to aid navigation. Some animals can predict earthquakes. Predators put these senses to lethal use: a shark homes in on the body electricity of its prey, vampire bats detect the infra-red radiation of blood, and a rattlesnake sees a 'heat picture' of its victim.
The lyrics as given in The Scottish Students' Song Book of 1897 are as follows: [2] Sing Ho! for a brave and a valiant bark, And a brisk and lively breeze, A jovial crew and a Captain too, to carry me over the seas, To carry me over the seas, my boys, To my true love so gay, She has taken a trip on a gallant ship Ten thousand miles away. Refrain
In active electrolocation, fish generate a weak electric field and sense the different distortions of that field created by objects that conduct or resist electricity. Active electrolocation is practised by two groups of weakly electric fish , the Gymnotiformes (knifefishes) and the Mormyridae (elephantfishes), and by Gymnarchus niloticus , the ...
