Whale sharks possess a broad, flattened head with a large mouth and two small eyes located at the front corners. [14] [15] Unlike many other sharks, whale shark mouths are located at the front of the head rather than on the underside of the head. [16] A 12.1 m (39.7 ft) whale shark was reported to have a mouth 1.55 m (5.1 ft) across. [17]
The word "song" is used to describe the pattern of regular and predictable sounds made by some species of whales, notably the humpback whale. This is included with or in comparison with music, and male humpback whales have been described as "inveterate composers" of songs that are "'strikingly similar' to human musical traditions". [3]
Like other whales, the male fin whale has been observed to make long, loud, low-frequency sounds. [19]Most sounds are frequency-modulated (FM) down-swept infrasonic pulses from 16 to 40 hertz frequency (the range of sounds that most humans can hear falls between 20 hertz and 20 kilohertz).
Even though the basking shark is considered to be slow and very large, it can actually breach the water, i.e. jump fully out, as some whales do. Despite the common myth that sharks are largely instinct-driven "eating machines", recent studies have indicated that many species possess powerful problem-solving skills, social complexity and curiosity.
The megamouth is considerably less active than the other filter-feeding sharks, the basking shark and the whale shark. The megamouth has a stout body and a long, wide bulbous head. Megamouths are large sharks, able to grow to 5.49 metres (18 ft 0 in) in length. [16] [17] [18] Mature males average at 4 m (13 ft) and females at 5 m (16 ft).
The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at high speed.
Many sharks can contract and dilate their pupils, like humans, something no teleost fish can do. Sharks have eyelids, but they do not blink because the surrounding water cleans their eyes. To protect their eyes some species have nictitating membranes. This membrane covers the eyes while hunting and when the shark is being attacked.
“The shark equivalent of a fist bump,” one commenter on Instagram said. Massive great white shark bumps whale-watching boat off California beach. See the video
