Was your interest in the ocean mostly concerning intertidal zones, or did you just want to physically stay out of the ocean? Because intertidal zones are super awesomesauce, but the fantastic and wicked weird alien stuff happens deeeeep down. See: CHEMOSYTHESIS oh my god I was 14 when I first learned about chemosynthesis and I still smile like a goddamned idiot whenever I think about it. Have a nice day and thank you for making me think about marine biology

I just want to physically stay out of the ocean. It’s too big and has too many things in it, and my body is not optimized for surviving within it. All of the ocean is cool, IMHO, from a microscopic level all the way to behemoths… but submarines and SCUBA diving freak me out. It’s not actually the animals that unsettle me, just the physics of tremendous amounts of water. Riptides? The bends? Water pressure? Drowning? Fucked up.

Shark of The Week: Epaulette Shark

Hemiscllium ocellatum, the epaulette shark is a small shark with several unique abilities. Growing to only around 3ft in length or less this is a very nonthreatening shark. These sharks are opportunistic feeders and may chew their food for up to 10 minutes after catching it, a habit very odd for a shark.They have very recognizable coloration, most noticeable are the two large black spots above each pectoral fin which give this shark its name. This shark has two dorsal fins which are equal in size and a long eel-like tail. Both the pectoral and pelvic fins are unique in shape, being round and paddle like.

The shape of these fins brings us to the epaulette shark’s first unique ability. This shark often ‘walks’ along the sea floor with it’s pectoral and pelvic fins, rather than swimming. Like all sharks they are very able bodies swimmers, but 'walking’ seems to be more common for these sharks as they normally only swim to escape a threat. These sharks are even capable of traveling out of the water for short distances to reach tidal pools.

The habitat range of the species is rather small. Living only on the northern coast of Australia, New Guinea, and its surrounding islands. The epaulette shark mainly stays in shallow coastal water near reefs, coral flats, and tidal pools. They have been reported in waters up to 160ft deep but this is uncommon.

Mating season takes place from July through December, though in captivity these shark will mate year round. Unlike many species matting is often initiated by the female shark, who will follow and bite at the male. The epaulette shark is oviparous and lays its eggs in August up through December.  The female shark will deposit two eggs every day for up to 14 days; on rare occasions she may deposit 4 in one day. Clutches of eggs can be quite large ranging from 20-50 eggs laid. The eggs are around 3in long and will incubate for 120-130 days before hatching. At birth pups are only 5-6in in length.

The last thing that should be noted is the second unique ability of this species. These sharks are largely nocturnal and spend much of their time in tidal pools and shallow reef areas. Receding tides often cut these areas off from the ocean at night. Over the course of the night the oxygen levels in these waters can drop by 80% or more due to the respiration of the animals with in them. This brings us the the epaulette shark’s ability, they can survive in extremely hypoxic conditions. They can survive for hours in water with only 5% oxygen in it with out losing any of their responsiveness.

These sharks are harmless to humans. They are slow moving and are often reported as showing no fear of humans. However, like any shark they can bite if handled improperly or intentionally provoked.

(Note how rounded the fins are)

That’s it for this weeks Shark of The Week! Hope you enjoyed and found it educational. Please re-blog to share the knowledge!

Previous Shark of The Week: Longfin Mako

So before Keith and Lance start a relationship, one mission has them end up on this planet full of aquatic aliens and they immediately begin fawning over Lance in his monster from. Lance is bitter because, really? The ladies are only attracted to him when he’s a walking shark?! REALLY?!

Meanwhile Keith is angry about it but not sure why seeing these people flirt with the Blue paladin is pissing him off. He occasionally even lets out these low angry kitty growls, much to Shiro’s and Pidge amusement.

Today I saw cancer, cigarettes, and shortness of breath. This is why I walk to the ocean. Swim with sharks and jellyfish. I may never get this chance again. This is why if you want to kiss, you should kiss. If you want to cry, you should cry. And if you want to live, you should live. You don’t have to love me. You already did.
