Here's what to know:
* Black and White Dominate: The majority of killer whales have a predominantly black body with white patches on their belly, eyes, and a dorsal fin that can extend to the tail.
* Greyish Tones: Some orcas may have a greyish or brownish hue, particularly in areas where they've been exposed to the sun for extended periods.
* Transient vs. Resident: Some killer whale populations exhibit different color patterns. For instance, transient orcas (which roam widely) are often darker than resident orcas (those that stay within a specific area).
* Rare Color Variations: In extremely rare cases, killer whales have been documented with albino or melanistic (completely black) coloration.
So, while the typical killer whale is black and white, there are subtle variations and rare exceptions to this rule.
