2-good luck sharks: incredible photos show relationship between fishermen, whale sharks - september 3, 2017 - this story originally appeared on biographic.
the largest and arguably most magnificent fish in the sea can reach a staggering 12 meters (40 feet) in length and tip the scales at 18 metric tons. despite its colossal proportions and the relative ease with which it can be observed when it gathers in large breeding aggregations, scientists know surprisingly little about this spectacular creature. the whale shark (rhincodon typus) is indeed a fish, not a whale: it breathes through gills, is cold-blooded, and possesses a skeleton made of cartilage. the “whale” portion of its common name is a reference to the animal’s immense size and manner of feeding, rather than any close relation to marine mammals. while these gargantuan diners could swallow much larger prey, they eat mostly minute plankton as well as small fish and squid that blunder across their path. the sharks sieve these organisms from the ocean in the same way that baleen whales do, cruising near the surface, s*****g in huge mouthfuls of water and the precious nutrients it contains. curiously, whale sharks have more than 3,000 tiny teeth, aligned in bands that look like rough metal files, inside their impressively wide jaws, but evolution has long since abandoned whatever function the teeth once served. #protectwhatyoulove#sharkbytes#sharkbytesapp#sharkweek#shark#saveoursharks#sharks#sharkawareness#ilovesharks#sharky#scuba#surf#beach#fishing#savesharks#sharklover#sharkconservation#learnsupportprotect#learn#support#protect#finalliance#elasmobranch#ourblueplanet#savetheoceans@lola_supertramp@otistheshark@mermaid_yogini
