Tube dwelling anemone Ceriantharians have a crown of tentacles that are composed of two whorls of distinctly different sized tentacles. The outer whorl consists of large tentacles that extend outwards. These tentacles taper to points and are mostly used in food capture and defence. The smaller inner tentacles are held more erect than the larger lateral tentacles and are used for food manipulation and ingestion.

Did you have to look twice before you saw it? Indian ocean Walkman (Inimicus didactylus) Closeup profile portrait. Due to the fact that this species lives a fairly sedentary life, mostly buried in sand it will often become riddled with parasites, algae and crustaceans due to the amount of time spent motionless waiting for prey. Fortunately for the indian oceanic walkman this isn’t much of a problem as it has the ability to shed its outer layer, effectively getting rid of any unwanted passengers. When disturbed by a potential predator, the indian ocean walkman fans out its brilliantly colored pectoral and caudal fins as a warning. Once dug in, it is very reluctant to leave its hiding place. When it does move, it displays an unusual way of moving, it crawls slowly along the seabed, employing the four lower rays (two on each side) of its pectoral fins as legs.

Today is the last day of #sharkweek which means it is the last day of me featuring my #shark pictures. Brownbanded bamboo shark, (Chiloscyllium punctatum) the most amazing fact about this shark is it can survive out of the water for up to 12 hrs. Concave posterior margined dorsal fin. No color patterns for the adults but the juveniles have dark transverse bands with some dark spots. These sharks are nocturnal animals and Classified as Near Threatened (NT) on the IUCN Red List. Its minimum population doubling is 4.5–14 years range. The major threats to these sharks are the loss of their habitat, pollution, and hunting (both for aquarium trade as well as food). Reproduction is oviparous.

Because it’s #sharkweek I feature my #shark pictures. Sharks need protection! This is a picture of my first whale shark I’ve ever seen. Whale sharks are the biggest fish in the world and grow to a Max of 12m and 9 metric tonnes. Whale sharks have a mouth that can be 1.5 m (4.9 ft) wide, containing 300 to 350 rows of tiny teeth and 20 filter pads which it uses to filter feed plankton and small fish. They reach sexual maturity at around 30 years and their lifespan is an estimated 70.

Even on a close-up shot of a flounder it is pretty much invisible isn’t it? Did you know? Flounders are born with one eye on either side of their head, like any normal fish. However, during the course of early development, one eye migrates over the top of the head to the other side, twisting the skull in the process. As this happens, the fish changes from an upright-swimming planktonic larva to a juvenile that lies on one side when it settles to the bottom. The upper side of the fish retains normal coloration, while the lower side becomes white.

Today is Earth overshoot day. July 29 marks Earth Overshoot Day (EOD), and for the rest of 2019 all the energy humanity uses is unsustainable in the long term. It is the earliest that EOD has ever fallen, and means humans are using nature 1.75 times faster than Earth’s ecosystems can regenerate. It means that in just seven months, humans have exhausted the amount of water, soil, clean air and other resources that the planet can generate in 2019, meaning from now until December all the energy we use is unsustainable in the long-term. The extra waste we now produce cannot be absorbed and will cause harm, and we are using too many other natural resources – like eating fish, plant-based food and meat – too quickly. Reduce your carbon footprint! There are easy ways to do so! • Buy fish once a week (not 5 times). • Eat fish from sustainable resources know where and how it has been caught! https://ift.tt/XveAuR • Lower your own standards and carbon footprint. • Turn off the water while soaping under the shower. • Turn off lights which are not needed. • Leave your car at home and take a walk or a bicycle. • Don’t go to the Gym by car and then sit on the bike. • Do not throw your rubbish over board or on the side of the street eventually it’ll end in our Oceans. • If you have to use Plastic, use reusable Plastic containers • Bring your own Bag to the Market • Recycle • Cut energy use at home • Minimise waste • Grow your own fruit, veg and herbs • Instal energy efficient appliances at home • Compost • Car pool and use public transport • Go plastic free • Buy from charity shops • Cut down on meat consumption Taken by #Underwaterphotographer #DanielSasse #Scubadiving #Aonang #Krabi #photooftheday #Marinelifeprotection #Ouroceans #Underwaterphotography #Fortheoceans #nature #uwpic #Savetheoceans #Marineconservation #Oceandefender #Saveourseas #underwaterlife #fish #ecowarrior #wildlife #underwaterworld

First time I’ve seen a Marbled shrimp (Saron marmoratus) here. It’s also known as the Saron Shrimp, Eyespot Shrimp or Carid Shrimp. There seems to be some debate as to whether their present taxonomy is correct.
