Eventually this page will be where club members videos are displayed for all to see

Club Members Videos

The long term aim is that club members who take videos will be able to have them linked to this page to showcase the diving done both in and outside of the club rmentum.

The current videos on there are a mixture of videos chosen at random off You Tube and one I took in Australia a few years ago. If you have any videos you want to show to the club members (and indeed the whole of the Internet) then please let me have them on a memory stick, or if you have posted them to Youtube just let me have a link to the video and I'll do the rest.

This video is of a blue ringed octopus The blue-ringed octopuses (genus Hapalochlaena) are three (or perhaps four) octopus species that live in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia. Their primary habitat is around southern New South Wales, South Australia, and northern Western Australia.[1][2] They are recognized as one of the world's most venomous marine animals.[3] Despite their small size, 12 to 20 cm (5 to 8 in), and relatively docile nature, they are dangerous to humans if provoked and handled, because their venom is powerful enough to kill humans. They can be identified by their characteristic blue and black rings, and yellowish skin. When the octopus is agitated, the brown patches darken dramatically, iridescent blue rings, or clumps of rings, appear and pulsate within the maculae. Typically, 50–60 blue rings cover the dorsal and lateral surfaces of the mantle. They hunt small crabs, hermit crabs, and shrimp.

We took these videos in 2011 whilst visiting Ningaloo and Coral bay in Western Australia.

The whale shark (Rhincodon typus) is a slow-moving filter feeding shark and the largest known extant fish species. The largest confirmed individual had a length of 12.65 m (41.5 ft) and a weight of about 21.5 t (47,000 lb), and unconfirmed reports of considerably larger whale sharks exist. Claims of individuals over 14 m (46 ft) long and weighing at least 30 t (66,000 lb) are not uncommon.[citation needed] The whale shark holds many records for sheer size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate. It is the sole member of the genus Rhincodon and the family, Rhincodontidae (called Rhiniodon and Rhinodontidae before 1984), which belongs to the subclass Elasmobranchii in the class Chondrichthyes. The species originated about 60 million years ago. The whale shark is found in open waters of the tropical oceans and is rarely found in water below 22 °C (72 °F). Modeling suggests a lifespan of about 70 years, but measurements have proven difficult.[3] Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth shark and the basking shark. They feed almost exclusively on plankton and therefore, are completely harmless to humans.

I'm sure many club members have dived the Thistlegorm many times over the years, this video shown a dive done

The SS Thistlegorm was a British armed Merchant Navy ship built in 1940 by Joseph Thompson & Son in Sunderland, England. She was sunk on 6 October 1941 near Ras Muhammad in the Red Sea and is now a well known diving site.
