Orlando SeaLife Aquarium Welcomes New Sharks For Grand Opening

 Sea Life Orlando will be opening on International Drive in Orlando on May 4, 2015. Anyone who has ever been to Orlando knows International Drive is the hub of activity in the ever popular tourist destination. The Aquarium will feature a 360 degree ocean tunnel, a rockpool experience and an interactive talking aquarium for the kids. Three new sharks were just transported from the Sea Life Kansas City and San Diego locations. The Aquarium has an independent charity, The Sea Life Marine Conservation Trust, with money donated from every ticket sale.This aquarium should be an exciting and welcome addition to the Orlando attractions. MOREMore:

Dr. Sanjay Joshi Delivers New Photon Hybrid (just don’t air ship them because we all know how that goes)

Juvenile Half Black Picasso Photon (Hybrid)

 Meet the newest member of Sanjay’s Photon Clownfish family tree – The Half Black Picasso Photon! A true love story for the ages, the Photons all stem from a rather licentious female Onyx Percula (A. percula var. Onyx) Dr. Joshi picked up along with her chosen mate, a Black Ocellaris (A. ocellaris var. Darwin) in Colorado he dubbed “The Odd Couple”. Following the first unexpected spawns in 2009 that resulted in the handsome hybrid, the Black Photon Clownfish, and the loss of the original male, the female was paired with a subsequent string of suitors (a few of which were fated to murder). Sanjay threw us another surprise when the frisky female successfully paired with her own progeny in 2011, bringing us the Half Black Photon and, more excitingly, proved that the hybrids were indeed fertile (you can read a bit more about the history here). It’s been a while since we’ve since seen anything new on the Photon front, so we’re pretty giddy to announce the most recent spawning of a male Bali Picasso and a female Half Black Photon!… More:

School of Baby Caribbean Reef Squids Video

embedded contentGood morning friends, as I drove into work this morning and looked into the water I saw our school of baby squids had seemingly grown overnight and figured there was no time like the present to jump in and shoot a little video for you all. These little sweethearts were born here and will stay here until they are old enough to head out to reef. I constantly see adult females laying eggs under our rocks and then “PRESTO” months later we have new baby squids. These here vary in size from about 1-4 inches and have been in our little protected lagoon for quite some time now, I’m thinking about a month. During the days and especially at night they are out hunting non-stop and they seem to have no problem catching small fish, they are master hunters

A Database for the Identification of Sponges

There is a huge number of sponge species in our world’s oceans. Some of them are bacterivores, some are carnivorous, some even harbor zooxanthellae. Yet, despite their great diversity of function, sponges are highly conserved in form. Often, differences between even distant relatives are so subtle that only trained experts with the right tools are capable of conclusively identifying them. Because there are so many different but similar species, traditional field guides (especially those in print form) are pretty much useless. The difficulty in identifying these primitive animals has been blamed for a general lack of attention to the group by biologists. That notwithstanding, comprehensive, well-illustrated and regularly updated catalogs of sponges are much needed; this is especially so if one considers the abundance and ecological importance of sponges in nature, and the fact that sponges are becoming even more ubiquitous as many coral species decline. The Sponge Guide, an online database devoted to sponge identification, has been notably filling this gap. Because it is electronic, it can be more extensive and be easily updated as needed. Work on the guide began in 2000, when sponge taxonomist Sven Zea was conducting research in the Bahamas under Joseph R. Pawlik. Over the next decade the pair was joined by Timothy P. Henkel, who was to contribute his knowledge of databases and computer programming. Though it was initially meant for use by researchers in the expedition, the photographic database (tSG, spongeguide.org) was eventually published online in 2009. And, then they just kept adding to it. Recently, the collaborators have launched the third edition of the database.… More:

Sleeping Stoplight Parrotfish Video Clip, Curacao

embedded content Hi friends, I have another fun video for you all today of a big adult Stoplight Parrotfish sleeping with his head propped up on a rock and his body laying in the sand. Aimee and I never get tired of seeing this, I mean who would have even guessed that fish sleep?? On any given night dive we see about 20-30 parrotfish, all different species and sizes fast asleep in the weirdest of places! For instance we usually see parrotfish stuck in tube sponges or laying flat up against rocks and it’s not uncommon to find them inside barrel sponges and hidden under algae, honestly if you really look they are everywhere! When I find them out in the open like this one they can be very hard to approach as light will scare them. I’ve learned that coming in very slowly with a non-threatening approach usually works, just be calm and quiet, get in and get out!

A Review of the Vivid Coral Film

SAM_0880 (1)
Some time ago I received a product sample from Vivid Coral Technologies. It appeared to be a 2″x4″ section of thin, amber-colored plastic sheet material. It is essentially a blue color filter, removing about 80% of blue light. The purpose of using this product, according to the company, is to create an enhanced and more natural-looking view of aquarium inhabitants while protecting the viewer’s eyes from harmful, excessive blue light glare. It basically allows the aquarist to use intense blue lighting on the aquarium while reducing its undesirable visual effects. It comes in a variety of sizes of sheets, which are apparently applied to the tank panel much like auto glass tint. The first thing I did was try it out with my own light, an AI Hydra 52. Run full blast, Hydras are really… More:
