Photo: Thomas Peschak @thomaspeschak 'The waters around the northern Galápagos Islands of Wolf and Darwin are one of few places in the world where mature adult whale sharks make regular seasonal appearances. This 6-8 foot silky shark is dwarfed by a giant 30 + foot female. Photographing theses giant sharks is difficult, the currents are ripping and they swim incredibly fast and show little curiosity for people. Shot on assignment @natgeo magazine for a story on climate change and the Galápagos Islands in the June 2017 issue.

An update from our D'Arros Research Centre in the Seychelles:
'A lemon shark swims away with some new bling as part of our ongoing study of this species' behavioral patterns in St Joseph Atoll, Seychelles. This ADL (accelerometer data logger) tag records the shark's swimming speed, direction and tail beat frequency. The antennae off the back? That's how we retrieve both the tag and the data. Once the whole package pops off the shark, after roughly 48 hours, we use a VHF receiver to pick up the tag's unique transmission and track it down. Three deployments result in over 5 million rows of data. • • • #darros#seychelles#seychellesislands#sharks#sharktagging#sharkresearch#lemonshark#bling

Just like us, manta rays love a good feed, so when plankton blooms are thick they have some impressive strategies for making the most of conditions. Sometimes they will form a feeding chain; swimming in line, head to tail, each ray positioned slightly higher than the one in front. It is believed that by doing this they can each catch the plankton that has tried to escape the path of the manta in front.

This northern corner of the Galápagos Islands is home to the greatest abundance of sharks anywhere on the planet.

Nurse sharks use Bimini's waters year-round but the next couple of months are particularly important for reproduction --- lots of mating pairs in the shallows ! Great time to be a nurse shark.' •
Not all sharks are the size of the great white shark! We’ve seen plenty of lesser known but just as interesting sharks during this week’s rvsolander expedition to Exmouth Gulf, species like this Australian sharpnose shark. These critters only grow to 70-80 cm, so this one is fully grown. These cool little sharks are endemic to Australia, though most Australians have never seen or heard of them.
As it's Mother's Day on Sunday we have some exciting posts to share with you! In recent weeks the sharklab has caught and tagged several pregnant sharks!! In this video you can see several pups on the ultrasound. What is even more incredible is this shark was caught first in 2003 as a juvenile and is now returning to Bimini with her own pups! Stay tuned for our tiger shark video Also a massive thank you to #EImedical for the donation of their ibex pro ultrasound machine!' •
Check out this little guy! It's a Sargassum Frogfish which had been on researcher @tomburd's wish list for a while.
However it wasn't a completely natural encounter as Tom and the team came across this beauty when pulling up a large pile of tangled fishing nets during their manta trip. Unfortunately this frogfish (and a group of little shrimps) were using the mass of ghost fishing gear as their home.

'The last seven days marked the first week of this years’ research season on the great hammerhead sharks in Bimini during which we did not see a single hammerhead.
This allowed us to prepare the upcoming data analysis. Crucial in being able to investigate possible impacts of the daily provisioning on the movement and behavioural ecology of the great hammerheads in Bimini will be the movement data we receive from individuals that have been tagged with an internal 10-year acoustic transmitter.
Acoustic telemetry tools have been used in the study of marine animal behaviour for more than 60 years. Our great hammerhead sharks are passively tracked by using internal acoustic transmitters that emit coded sound pulses at a known frequency. If a tagged individual swims within proximity of a submersible receiver of our acoustic receiver array around Bimini, the signals emitted by the transmitter are being processed and recorded. The deployment of receivers at specific locations allow us to passively monitor individual movement patterns.
To retrieve the data from the receivers, the receivers have to be recovered and the data has to be downloaded. We started the data download of our 62 receivers last week and we will continue to do so during the next 7 days until we have the complete data set ready for the analysis. • #bimini#sharklab#bahamas#shark#science#research#marine#biology#hammerhead#ocean#sea#conservation

'Despite having a formidable caveman-esque weapon for a head freshwater sawfish still end up as lunch in Australia! This photo was published recently in an article by Murdoch University scientists documenting crocodile and bull shark attacks on sawfish in the Fitzroy river, Western Australia. You would have thought being critically endangered was enough to deal with but monster too .
The research has been published in the May issue of the journal Ecology in the new series, The Scientific Naturalist. #Repost@wildlife.hd

'If you haven't seen this already then where have you been the past few days ? Beautiful footage of a huge bull shark peacefully patrolling the Bimini shoreline. Taken via drone by our former media manager @duncan_brake ! Although slightly nerve-racking for most to see an animal of this size and reputation so close to the beach, to us shark geeks it is a breathtaking sight!' #bimini#bullshark#sharks#sharkweek#taurus#taurian

A floating mass of tens of thousands of squid eggs pushed by the current into a lagoon of Bassas da India. This tiny French atoll, with a landmass smaller than The Mall in Washington DC, is halfway between Mozambique and Madagascar. In a place that has become a ship graveyard, I found it incredible to come across such a fragile, yet intact mobile incubator.'

As the spring flowers bloom on land, the bloom of mysids are seen in staggering numbers in the #greatbearsea. Also called opossum shrimp, they get their name from their habit of brooding in a special pouch or "marsupium" in females. Small and transparent, mysids resemble a crayfish and tend to be omnivorous, eating smaller planktonic organisms. In the waters of the Great Bear Sea, they are usually eaten by small fish or large shrimp. But on the California coast, they have also been the target of a few other hungry sea creatures, like marine leeches. There are only two species of ambitious leech who target the opossum shrimp and each come with tail suckers. Scientific American did a feature piece on these suckers that latch onto these shrimp-like crustaceans titled "Wonderful Things: Opossum Shrimp Leeches” and cite that "opossum shrimp leeches combine three concepts that do not seem to belong together into one awesome parasite -- a parasite that also happens to be one-quarter of the size of its host: In human terms, this would be a parasite the length of your lower leg. It’s definitely a drag for the opossum shrimp." • #oceanfeedstherainforest#shrimp#leech#parasite#creepy#hungry#underwaterphotography#marine

• 'White spotted eagle rays in flight formation at Wolf Island in the north of the Galapagos. Perfectly synchronised, they glide through ocean currents with mesmerising elegance! These beautiful and charismatic rays have powerful jaws to feed on a variety of invertebrates including hard shell molluscs (clams, oysters, etc.) that grow attached to the seabed. This lot seems to be resident to the landslide dive site at Wolf Island as we always tend to encounter them during our science trips. When I see them, I always wonder: how many clumsy divers have they witnessed over the years while they effortlessly enjoy the ride ?! Taken during a @darwinfound and @saveourseasfoundation trip to study #sharks abundance and diversity using #Bruvs.' • #conservation#exploration#research
