The world that lies beneath the surface of the water is equally as complex as the one on dry land we live in, if not more so. On this page you'll find just some of the work our researchers are doing to explore the vast marine environment, with some great activities for kids here.

How big is a great white shark when it's born? Until recently no one could say for sure.

Our Head of Natural Sciences and resident fish expert Tom Trnski frequently gets calls about strange fishes washed up on a beach or caught by curious anglers. One of the most exciting reports was of a small white shark found at the northern end of Ninety Mile Beach, on the West Coast of the North Island.

This shark, named Rehutai by Ngāti Kuri, measures 105cm which turns out to be the smallest free-swimming white shark ever recorded, and provides new knowledge on the life history of this charismatic species.

This video tells more of the story behind the discovery, naming and preparation of Rehutai for the collection at the Auckland Museum.

The enormous sunfish, which can easily grow to be bigger than a car, starts life as a tiny, cartoonish dot. These larvae are not just small but also incredibly scarce - you could probably hold all of the specimens found in the 20th century in the palm of your hand. Read about how one late-night email had one of our scientists jumping with excitement, and what it means for what we know about this charming fish.

An inside job


Our Natural Sciences team got the rare opportunity to dissect a massive 100kg squid, answering in the process some longstanding questions and presenting some new mysteries, too.

The deep-sea dweller was caught (already deceased) by a fishing vessel off Whakaari (White Island), and while it was originally reported to be a giant squid, it is in fact a large octopus squid. This specimen has been identified as Taningia fimbria, which is one of the largest identified squid species. This animal has amazing photophores (bioluminescent light-producing organs) on two of the arms, as well as about 200 cat-like claws. 

Alongside teams from Waikato University, Massey University and Auckland University of Technology, our scientists will use what they've discovered through the dissection to learn not just about the squid itself but also its environment and, for example, whether the waters around Whakaari were affected by toxicity after last year’s eruption.

Auckland's vast and varied coastline comes with a lot of perks - great views, great beaches, and also a hundreds of species of seaweed. Auckland Museum's herbarium is home to more than five thousand specimens. Find out more about the seaweed you see everywhere as well as some of the rarer varieties.
