We regularly post short Marine Wildlife Videos an Photographs with a short explanation regarding the subject and the technique used to capture the image.

Thank you, you made our day!

Subject: A bloom of Comb Jellies drifts by underneath the water surface. These free-floating Ctenophores are not Jellyfishes and do not sting. Their limited locomotion is generated by eight rows of hair-cilia that beat in coordinated waves. These strokes also generate iridescent light waves (iridescent light =is the phenomenon of certain surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes, like in soap bubbles).

Technique: The alien appearance of these primitive animals reminded me of a sentence in the song "Eve of the War", the opening piece from the British 1978 album, Jeff Wayne's Musical Version of The War of the Worlds; “The chances of anything coming from Mars are a million to one, he said… but still, they come.” I thought it was a very good match with the thousands of jellies drifting by over our head while performing a safety stop at the end of our dive.

  • Olivier - Beyond Scuba

Subject: The Striped Catfish (Plotosus lineatus) is one of the very few catfish species that is found in saltwater. Schools of these fish are known to swim up rivers on Africa’s east coasts. The spines of the first dorsal and of the pectoral fins are venomous, and can be lethal, a good reason for the Convict Blenny (Pholidichthys leucataenia) to mimic this species. While juvenile Striped Catfish swim in dense ball-shaped schools, the adults hide in smaller groups under ledges and overhangs during the day. Here in this video we see how a school is deepening out a ledge and turning it into a suitable day-shelter. Fun fact: after observing and looking several times at the footage used in this clip we’ve noticed that there are some individuals in this school that are pretending to move sand but that are actually faking their work efforts and they, in contrast to most of them, spit out nothing.

Technique: “Sixteen Tons” was written by Merle Davis in 1946 and released for the first time a year later. This song based on the life of American coal miners broke through in 1955 with Tennessee Ernie Ford’s version of it. More than 70 different versions were made over time by diverse musicians and artists in various languages. We preferred to use an instrumental version of this folk song to accompany this short clip.

Subject: The eye of the Glasseye (Heteropriacanthus cruentatus), a member of the Bigeyes family (Priacanthidae), is extremely well adapted for life in obscure milieus. They have, like all other Bigeyes family members, big spherical lenses and photoreceptors specialized to see in dark and low-light environments. This nocturnal feeder of small octopuses, tiny squids, crabs and shrimps is also able to rapidly intensify and fade its reddish colour and silver patterns.

Technique: To make this reddish fish stand out we’ve desaturated the pinkish/purplish algae shrubbery in the foreground slightly.
