Rediscovering the Hancock Coelacanth

Written by Dan Gordon, Keeper of Biology, The Great North Museum: Hancock.

For as long as I’d worked at the museum, there’d always been a Coelacanth. People referred to it in passing, pointing out the large tub of orange tinted spirit where it lurked. I’d always rather taken it for granted; an interesting but rather mundane specimen, and I’d never been curious enough to fish it out of the murky liquid and examine it.

That is, until 2018, when staff at the National Maritime Museum Cornwall got in touch about an exhibition they were putting together called Monsters of the Deep. They’d asked us about Coelacanth fossils and I mentioned the Coelacanth in the fish collection, which was greeted with some surprise. A real one…Would we consider a loan? And as I thought about this, I came to realise that I knew very little about the Coelacanth at all.

There was next to nothing in the catalogue about it, so I decided, firstly, to get a better look. This was easier said than done. The Coelacanth is over a metre long and weighed over 20kg, sitting in a container of tea coloured alcohol bigger than a bathtub. Reaching in, I ran my gloved fingers over its flanks, which had the texture of coarse sandpaper. Lifting it out was like wrestling an alligator, but eventually it emerged, a gaping mouth with small sharp teeth, a ragged tear through the flesh of its head, and the huge eyes of a deep-water dweller.

Snagged Setae 2, The Sequel: Packing Materials After 14 Years in Fluid Storage

By Lu Allington-Jones (Senior Conservator), Wren Montgomery (FTIR Specialist) and Emma Sherlock (Senior Curator), The Natural History Museum, London UK

Many years ago, we undertook some research into a suitable replacement for cotton wool as bungs for vials holding small fluid-stored specimens. In 2008 we placed samples of Parafilm MTM, white Plastazote® LD45 and colourless HDPE (high-density polypropylene) lids in 10% formalin, 100% ethanol, and 80% IMS (Industrial Methylated Spirit, aka Industrial Denatured Alcohol) and allowed them to steep for 3 years. We undertook visual inspections, pH tests and FTIR analysis and concluded that Parafilm MTM was an unsuitable replacement, but that the other materials had undergone no change and had caused no contamination of the host fluids.  

We decided to revisit the samples after an additional 11 years on a south-west facing sunny lab windowsill, for a total of over 14 years of storage in the various fluids.

Cover page of The Herbarium Handbook

The new Herbarium Handbook is a key new addition to Kew Publishing’s series of handbooks, including The Plant Glossary and The Temperate Plant Families Identification Handbook. Unlike the other books in the series the Herbarium Handbook is a new version of a book first compiled and edited by Kew botanists some thirty-four years ago. The initial Herbarium Handbook came about following an extremely popular International Diploma Course in Herbarium Techniques at Kew. The demand to attend the course was so high that the number of applicants far exceeded places on the course. In view of the interest, the main information imparted during the course was published as a manual, widely recognised as an important reference for fundamental aspects of herbarium care and management.
