Cleared and stained Viperfish

This week in Fish: Grow a backbone!

This week we feature an incredible piece of research on deepsea fishes that have flexible 'necks' that lack vertebrae.  Bizarre!  Four new movies were loaded, a bunch of images added, and a new image gallery for triggerfishes was compiled.

Cleared and stained Viperfish

Grow a backbone!

Can you imagine living without the vertebrae in your neck?  Surely no animal on earth has a backbone that doesn't connect with its skull.  Think again ...

This week in Fish: Baby shark cannibals

This week we feature an incredible image of a Warty Prowfish shooting out a cloud of presumably toxic fluid.  We see Port Jackson Sharks mating and talk about cannibalistic shark embryos. The 12 new fish movies complete the current series on wrasses.  Thank you as always to all contributors.

A Port Jackson Shark with an egg case in its mouth

What's in a name?

Arggghhhh!  Nothing gets my goat more than reading a novel or a report that shows a scientific name with both the genus and species names with upper case letters or neither word in italics.
