New Zealand has a new species of seabird. Te Papa scientists recently described Imber’s petrel (Pterodroma imberi) from the Chatham Islands as a new species. A previous study that measured a large number of seabird bones from the Chatham Islands found three size categories. The largest bones belong to
Last week I performed the first DNA extraction in Te Papa’s brand new genetics laboratory. Our lab is the first genetics lab in a New Zealand museum and will allow Te Papa scientists to analyse the DNA of our unique plants and animals. Genetic information is increasingly being used to examine the
A new paper by Te Papa researchers and their colleagues from Massey University, NIWA and the Swedish Museum of Natural History, describes not one but THREE new species of hagfish. This increases the total number species found in New Zealand waters to eight. What are hagfish? These strange creatures, also
