Megamouth washes ashore in the Philippines

Megamouth shark in the Philippines

An incredibly neat and rare sighting of a megamouth shark has been confirmed in the Philippines. They are related to the basking shark and feed off of plankton and jellyfish. Not much is known about their range because they are so rarely seen in the wild.

I imagine they probably don’t have huge population numbers, and reside in the vast stretches of open ocean rarely traversed by humans, like the middle of the Indian Ocean and Southern Pacific.

Two-headed Bull shark fetus found

Pretty neat stuff here Рone of the only SIX recorded cases of a two headed shark in human existence. Even stranger, this is the first time this has been recorded in Bull Sharks.

Of course, this shark would not survive in the wild, and thanks to some observant fishermen, we now have a great specimen to study the mutational genetics of shark populations.

Splitting Sea Snakes

Sea snakes are the deadliest serpents on the planet. Their venom is ten times deadlier than a King Cobra’s. They also have the advantage of being extremely fast swimmers.

Don’t worry, they don’t regenerate like sea stars, but their recently explored evolutionary does show an interesting split.

If the distinction of being the deadliest snakes in the world weren’t enough, evidence now shows that the deadliest species of sea snake is actually a set of two species. Convergent evolution is the answer, essentially explaining that nature independently selected for the deadliest, most efficient sea-snake traits in two separate snake branches, culminating in two species that are essentially identical. FASCINATING.

I just hope I never see one on my side of the glass…
