This is just one of the many impacts of plastic pollution in the oceans. at odysea, where i volunteer at, they have instilled a trash cleanup called ‘debris in the desert’ where they pick up plastic to make creations such as this hammerhead shark, or their plastic chandelier. trash cleanup programs are so important and beneficial to the health of our oceans, demonstrating the negative impact it has. let me spit out some statistics for you 🐠
• it takes hundreds of years for plastics to break down! even when they’re “broken down” they’re still microplastics, which damage the earth just as much
• every piece of plastic ever created is still intact today
• plastic has been found within the bodies of organisms found in the mariana’s trench (deepest part of the ocean) • when plastics are eaten by sea birds, sea turtles, and whales, they are never digested or broken down. so when those animals eventually die from plastic clogging their body, it’s the only thing in there
• plastic is found in 90% of sea birds
• whales are recently starting to beach themselves because of how much plastic there is in the ocean and they cannot deal with it
horrible things such as this are the reason the ocean will be covered in plastic by the year 2050. something needs to happen now. it starts with us. stop using straws! take your own reusable bags to the grocery store! get a reusable water bottle! & so much more!!! we need to start helping now if we want the ocean to stay with us forever.

Many sharks are cold-blooded, meaning their body temperature is consistent with the water temperature. humans are warm blooded since we generally maintain a temperature that is higher than the environment. some sharks though are an exception! lamnid sharks include the white, porbeagle, mako and salmon sharks, and these are actually endotherms (carlson et al., 2004)! the lamnid sharks are able to preserve their metabolic heat through vascular counter current heat exchangers so that their body temp is higher than the water temp (carlson et al., 2004). the counter-current heat exchangers retain heat that would have been lost when blood is oxygenated at the gill lamellae (goldman, 1997). this generally causes them to have a higher metabolic rate compared to other shark species. white sharks benefit from this in that they can still hunt in cold temperatures and have a burst of speed that relies on a generation of heat. lamnid sharks also have retia, which is an arrangement of vessels that warm the eyes and brain of the shark (helfman et al., 1997). this has the potential of helping the shark see prey movement (brill et al., 2005). thresher sharks, belonging to the alopiidae family, also have retia!
