Animal Updates - October 4

Published October 04, 2013

Close to 20,000 animals representing more than 700 species call the National Aquarium home. There are constant changes, additions, and more going on behind the scenes that our guests may not notice during their visit. We want to share these fun updates with our community so we're bringing them to you in our weekly Animal Update posts!

Check our blog every Friday to find out what's going on... here's what's new this week!

Meet our Queensland Grouper!

Our Queensland grouper, Bertha, is one of Blacktip Reef's most distinguishable new residents! Since being introduced to her new home, Bertha has been happily exploring the nooks and crannies the reef - she especially loves the deep dive area!

Found in the warm waters of the Pacific, this large fish preys upon quite a variety of animals, including small sharks, rays, sea turtles, smaller fish, crabs and even spiny lobsters!

Measuring up to 9 feet in length and weighing around 800 pounds, Queensland groupers are the largest of reef bony fish species in the world! Apart from their sheer size, these fish can be easily recognized by their blotchy patterning and light yellow fins.

Check out this amazing footage of a giant Queensland grouper found off the coast of Heron Island (part of the Great Barrier Reef):

Did you know? Queensland groupers (like most other grouper species) are protogynous hermaphrodites! They start their lives as females and later will change sex once they hit sexual maturity.

Be sure to check back every Friday to find out what’s happening!
