Shark Organs

February 5, 2025

Sharks have a two chambered heart, stomach, gallbladder, pancreas, a tri-lobed liver (usually 15-35% of the total weight of the shark, in adult humans it is around 2%), intestines (these are relatively short in length, to compensate for this and to maximise nutrient absorption sharks have special valves to increase the surface area of the intestine; spiral, scroll or ring valves depending on the species), two kidneys, thymus, spleen, epigonal and leydig organs. Males have two internal testes and two external claspers, and females two ovaries and two oviducts.
