Tail fluke powers swimminghumpback whale

The tail fluke of the humpback whale breaks through the water as the tail is moved up and down, enabling powerful swimming.

Body designed for fast, efficient swimmingshortfin mako shark

The bodies of shortfin mako sharks and some tuna are designed for fast, efficient swimming thanks to internalized red muscle associated with a force-transmission system.

Tails aid fast swimmingswordfish

The tails of swordfish help them swim fast over long distances due to their stiffness and crescent shape.

Fins provide streamlined shapetuna

Fins of ocean-going fish such as tuna are streamlined because they fit close to the body in depressions and grooves when not needed.

Scales manipulate flowShortfin mako shark

Scales on sharks influence drag and thrust during swimming by manipulating fluid flow next to the body.

Contributed by Yann Dabbadie

As a naval architect, I am very interested in the application of nature's examples to marine design. There are many ways to improve actual boats (from sailing yachts to ships) by following nature's million's of years of evolution.At the moment,...
