[41] [24] In comparison, large great white sharks are generally around 6 meters (20 ft) in length, with a few contentious reports suggesting larger sizes. [42] [43] [35] The whale shark is the largest living fish, with one large female reported with a precaudal length of 15 meters (49 ft) and an estimated total length of 18.8 meters (62 ft).
Pygmy blue whale males average 83.5 tonnes (184,000 lb) to 99 tonnes (218,000 lb). [53] The weight of the heart of a stranded North Atlantic blue whale was 180 kg (400 lb), the largest known in any animal. [54] The record-holder blue whale was recorded at 173 tonnes (190 short tons), [55] with estimates of up to 199 tonnes (220 short tons). [56]
The whale may have interacted with the large extinct shark megalodon (Otodus megalodon), competing with it for a similar food source. Its extinction was probably caused by a cooling event at the end of the Miocene period causing a reduction in food populations.

A size comparison of a whale shark and a human. The cartilaginous fish are not directly related to the "bony fish," but are sometimes lumped together for simplicity in description. The largest living cartilaginous fish, of the order Orectolobiformes, is the whale shark (Rhincodon typus), of the world's tropical oceans.
Meg 2: The Trench hits theaters this week with a larger-than-life depiction of the megalodon. Here’s what we actually know about the beast, according to scientists.
It may have resembled the modern killer whale in appearance, and could represent a transitional species between the modern killer whale and other dolphins. O. citoniensis could have hunted fish and squid in pods, and coexisted with other large predators of the time such as the orcinine Hemisyntrachelus and the extinct shark Otodus megalodon.
