Love is in the Sea

Beneath the waves, some ocean animals have unique characteristics and interesting romantic relationships. Learn about how some sea creatures show their love.  

1. Travels the distance 

The leatherback sea turtle is the largest turtle in the world and undertakes the longest migrations between breeding and feeding areas of any sea turtle. In fact, some leatherbacks average 3,700 miles each way! Now that’s a long-distance relationship. 

2. Sings a love tune 

Humpback whales rely heavily on sound to communicate with each other in the water. During mating season, males will produce complex songs to attract a mate. Their songs are ever changing and evolving.  

3. Has the largest heart in the animal kingdom 

The blue whale has the biggest heart on the planet, the size of a small car and weighing in at about 400 pounds. A blue whale’s heart pumps approximately 60 gallons of blood with each beat. This is a big-hearted sea creature!   

4. Contains even more heart power 

The blue whale may have the biggest heart, but octopuses have three! They have two branchial hearts that pump blood through the gills to pick up oxygen and one systemic heart that circulates oxygenated blood to the body’s organs and muscles. 

5. Shares true attachment 

Deep-sea anglerfish have one of the most unique relationships. Males are significantly smaller than females, and their only goal in life is to find a female to physically latch onto. With his strong sense of smell, the male anglerfish will locate and bite a female, holding onto his love for the rest of his life. The male will provide the female with sperm to fertilize her eggs in exchange for nutrients from the female anglerfish.
