25 lip 2017 · Hydraulic system in fins gives tuna extra speed. New research suggests that pressurized hydraulic fin control—a vascular specialization that is unique among vertebrates—supports the ...
14 lis 2023 · Thanks to their unique torpedo-shaped bodies, smooth skin, and streamlined fins, tunas are fast swimmers. Albacore tuna can swim faster than 50 miles per hour. This helps them catch prey, avoid predators, and cover a lot of ground quickly during annual migrations.
Tuna have numerous morphological, physiological and behavioral adaptations to move rapidly through the water column and a sophisticated physiology that includes elevated metabolism, a unique cardiovascular system and a warm body temperature.
