A fish that suckles its young

I just read an amazing web page about a fish that suckles its young while they are still inside the female's body.

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.

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.

This week in Fish: Eel with a 'fishing rod tongue'

It's been a massive movie week! Also featured this week are fantastic images in the Whitespotted Anglerfish gallery. The 'strangest-fish-of-the-week' award has to go to Glenoglossa wassi.  This eel lacks a common name and has a tongue like a fishing rod.

This week in Fish: Candiru and Slingjaw Wrasse

This week we talk about the Candiru, a small fish that could give you big trouble.  You can watch the amazingly protrusible mouth of a Slingjaw Wrasse as it feeds and try to spot a newly settled Painted grinner buried in sand. Thank you as always to all our generous contributors!

Slingjaw Wrasse feeding

The Slingjaw Wrasse is aptly named.  The video shows excellent slow-motion footage of the greatly protrusible mouth during feeding. Click on the link to the fact sheet for more information on this species.

Humphead Maori Wrasse - up close and personal

This movie shows the species very nicely.  The fish swims so close to the camera it gives us a great view of its fleshy lips, colour pattern on the head and the forehead hump (click on the link to 'Hyperostosis - Swollen Bones' to find out more about this phenomenon).

Candiru - careful where you go...

Over the years quite a few people have asked me about the Candiru.  Is it really true that this fish can end up inside the bladder of an unfortunate person who urinates in the wrong stream?

This week in Fish: Deepsea anglerfishes and the Lilac-tip Basslet

Highlights for the week include a new movie from Agent 1 on 'The exciting life of Anglerfishes, a movie showing a halosaur at a depth of 1027 m and an outrageously coloured Lilac-tip Basslet swimming on the HMAS Brisbane.  Thank you as always to all our contributors.

Psychedelic frogfish makes a splash

In 2009, colleagues at the University of Washington, created quite a stir when they described a new species of frogfish from Indonesia.  The fish goes by the scientific name Histiophryne psychedelica.  When you watch the movie you'll probably agree that psychedelica is a good name for this strange fish.
