The marine eels and other members of the superorder  Elopomorpha have a leptocephalus larval stage, which are flat and transparent. This group is quite diverse, containing 801 species in 24 orders, 24 families and 156 genera (super diverse). 

Leptocephali have compressed bodies that contain jelly-like substances on the inside, with a thin layer of muscle with visible myomeres on the outside, a simple tube as a gut, dorsal and anal fins, but they lack pelvic fins. They also don’t have any red blood cells (most likely is respiration by passive diffusion), which they only begin produce when the change into the juvenile glass eel stage. Appears to feed on marine snow, tiny free-floating particles in the ocean.

This large size leptocephalus must be a species of Muraenidae (moray eels), and probably the larva of a long thin ribbon eel, which is metamorphosing, and is entering shallow water to finish metamorphosis into a young eel, in Bali, Indonesia.

A small and colorful male Ladybird Spider (Eresus cinnaberinus) slides under the much larger female for a precarious mating maneuver. The males grow to 11 mm, while the females are up to 20 mm in length. This species is found across Europe, though some scientists break up the 3 races of this spider into 3 species.

Scientists visualise the scars left by heart attacks

These images show (A) a healthy heart and (B) a heart damaged due to a lack of oxygen during a heart attack.

As you can see, the microstructure of a heart changes after a heart attack (B). The scar (outlined area), is formed because of the tissue death caused by a local lack of oxygen, and the consistency of muscle cell arrangement compared to the healthy heart (A) is lost. This will affect how much blood the heart can pump into the body within one heartbeat.

The images taken by BBSRC-funded researchers at the British Heart Foundation Experimental Magnetic Resonance Unit (BMRU), University of Oxford, were generated by a special type of imaging technique that measures the motion and movement of water molecules in the heart tissue.

This new technology, that Dr Jurgen Schneider and his team have developed, could eventually allow doctors to be able to look at a 3D+T representation of the patient’s heart, zoom-in on any relevant detail (a coronary vessel blockage or a damaged part of tissue), assess treatment options, and predict outcomes for the specific individual before the patient even enters the operating theatre. Much of this vision is still far ahead. Nonetheless, this research is vital to its development.

Fish of Baltic Sea
While the Baltic Sea might seem boring and mundane compared to tropical oceans, it has a fairly diverse and very odd assemblage of fish. It’s the world’s largest pool of brackish water, but it’s geologically so young, there are no specialized brackish water species.
So it’s a confusing mix. There are resilient ocean species, often smaller than their oceanic counterparts and unable to breed in some parts of the sea, and just as resilient freshwater fish venturing into the salty parts. Arctic fish mixed with temperate species coming from south. Oceanic fish that once invaded fresh waters and then returned here, now unable to tolerate full ocean salinity.
Fish that give birth, fish whose males get pregnant, fish whose eyes migrate over their heads during their lifetimes, fish that build nests, fish that smell like fresh cucumber. We have everything.

Seal pup at Yaquina Head Outstanding Natural Area 

A very young seal pup was spotted near the tide pools at Yaquina Head Outstanding Natural Area, surprising BLM staffers who are more accustomed to seeing baby seals in May or early June.

Meredith Matherly, the BLM education staffer at Yaquina who captured the photographs of the male pup, said the sighting on Cobble Beach was “extremely late in the season” but that there were no visible health issues.

“This one seemed healthy and happy, though,” said Matherly, adding that soon after the sighting the pup scooted into the water to meet mom and “ride on her back as he gets used to this big wide world!”
