A company named Ghost Pros is currently exploring the ship wrecks of Florida in search not of gold, silver or precious stones but of ghosts. The company is using the latest underwater ghost-detection technology, including submersible high powered sonar listening devices. Ghost Pro divers have also teamed up with Tampa’s Sea Viewers, the makers of high definition studio cameras which will be used to develop under water rovers.

“We’re listening to everything and anything we can down there,” says Ghost Pros’ Lee Ehrlich, explaining that you have to know what is not a ghost before you can find one. “[…] before you can tell you need to know what that ship sounds like alone,” he says.

Unlike Ghost Busters, Ghost Pros doesn’t get paid to hunt ghosts, but the search does generate a lot of attention from ghost aficionados and ghost critics, as well as from the general media. Hunting for the para-normal has proven to be an excellent way of creating some very normal buzz for Ehrlich and his companions, who – when not hunting down the ghosts of voyages past – are developing advanced submersibles for search and rescue operations.

As a diver, I would like to recommend any readers of this blog to leave the deep sea ghost hunting to professionals like Ehrlich and his crew. If you start seeing ghosts while scuba diving, make a safe ascendance and wait for the nitrogen poisoning to wear off.

A new species of ghost knifefish has been described by ichthyologists James Albert and William Crampton. It has been given the name Compsaraia samueli in honour of Samuel Albert who presented the scientists with the type specimens.

Ghost knifefish (family Apteronotidae) are famous for their body shape and for using a high frequency tone-type electric organ discharge (EOD) to communicate. The native home of these fishes are South and Central America. Within the aquarium hobby, the Black ghost knifefish (Apteronotus albifrons) and Brown ghost knifefish (Apteronotus leptorhynchus) are fairly common.

Samuel’s ghost knifefish lives in the western Amazon of Peru and Brazil and was collected from flooded beaches and deep river channels. It can be distinguished from its close relatives by having a higher number of caudal-fin rays and a less tapering body shape in lateral profile.

Other distinctive features are the relatively short caudal peduncle and the comparatively small body size (as an adult). The mature male sports an extremely slender and elongated snout and engages in sparring with repeated aggressive non-contact postures, usually followed by jaw-locking and biting.

Genus: Compsaraia

New species: Compsaraia samueli

Former Italian Navy diver Pino Termini of Naples claims to have seen the ghost of Steve Irwin while diving at Batt Reef in tropical North Queensland. Batt Reef is a coral reef off Port Douglas in Queensland, Australia and a part the Great Barrier Reef.

“As I started my dive I saw somebody and was surprised because I saw no other boats around”, Termini explains. “Then I noticed that the person had no oxygen tank or mask, the person swam towards me and I realised that it was none other than the crocodile hunter himself: Steve Irwin. I freaked out, but he looked calm and at peace. I have seen a lot underwater but never a ghost. It was as if he was looking after the spot where he met his end, I felt that I should not impose myself on his turf as it was his and it seemed as if he was caring for the living creatures there.”

Pino Termini dived for the Italian Navy for seven years and now spends most of his time travelling around the world looking for great dive sites.

Steve “The Crocodile Hunter“ Irwin died at Batt Reef in 2006 after being fatally pierced in the chest by a stingray barb.
