Octopuses have 3 hearts! Two pump blood to their gills, and one circulates it throughout their body. Fascinating marine biology from Smithsonian Science. 🐙 Source: https://www.si.edu/explore/science #science #marinebiology

Hello Ladies & Gentlemen! In collaboration with our brilliant Social Media Volunteers, we created a series of informational graphics on sustainable fisheries. Today’s graphic focuses on bycatch & trawling.

Bycatch is the accidental catching of non-targeted species during commercial fishing operations. Bycatch could include non-target species, young fish, and protected species. It is a complicated issue that affects marine wildlife globally.

Trawling is the act of towing a large net across the ocean floor with a boat to capture certain species of crabs or ground fish. The mesh net is designed to contain the fish inside the net as they reel it up to the surface. There are two different types of trawling, bottom trawling, which includes scraping the sea floor, and midwater trawling.

Trawling has negative effects on other marine life in the ocean that are not the intended targets of catch. They can become entangled while foraging. Animals such as pilot whales, dolphins, and sea turtles are at high risk of being caught in bottom trawl; they may drown, get injured, or face stress and exhaustion from the capture and release. Trawling does not have to cease entirely, there are ways it can remain a sustainable approach to capturing fish.

For instance, in the case of sea turtles, fisheries have introduced turtle exclusion devices which are a grid of bars with an opening near the end of the trawl net which allows for turtles to escape. This has greatly reduced turtle mortality rates in trawl fisheries. Trawling also does environmental damage to the ocean floor, damaging coral & delicate habitats. Some recommended methods to control this method of catching fish are to reduce the number of tows at night and reducing the duration of each tow.

I cant not share these two funky little dudes we found on an Aglaophenia specimen from a recent invert zoology lab.

The first image is a Skeleton shrimp, and the second is a species of Doto sea slug <3

Drifting far from land in the deep Pacific, the yellow-bellied sea snake is a true ocean anomaly. This daring reptile has completely severed ties to the shore, living its entire life at sea!
