Why do whales breach? 🐋 Whales breach for various reasons as this behavior likely serves different functions throughout the course of their lives. Repeated breaching helps calves build vital energy stores and muscle needed to migrate back to feeding grounds by increasing myoglobin levels in their tissue. A protein found in muscle cells, myoglobin is iron- and oxygen-binding and likely extends humpbacks’ breath-holding ability when diving. 🐋 📸Research activities authorized under NMFS/MMPA ESA

How many breaches do you count? Why do these calves breach multiple times? Repeated breaching helps calves build vital energy stores and muscle needed to migrate back to feeding grounds by increasing myoglobin levels in their tissue. A protein found in muscle cells, myoglobin is iron- and oxygen-binding and likely extends humpbacks’ breath-holding ability when diving. 🐋 This could be an example of that behavior! 🩵 📸Research activities authorized under NMFS/MMPA ESA Permit #21321 following all

15 reactions | Watching a humpback breaching never gets old. Our drone got this video while collecting whale blow samples during a Parley SnotBot expedition to Alaska. Read about our Alaska expeditions here. https://www.whale.org/?s=Alaska+and+snotbot | Ocean Alliance | Facebook
