Guess hoo-hoo it is 🦉

The owlfish, named for the size of its large eyes relative to its head, lives throughout the North Pacific. These species are in the family Bathylagidae and are relatively common in the deep sea, living at depths of over 6,000 meters (19,685 feet). In Monterey Bay, we observe these fish between a few hundred meters to over 2,000 meters (6,560 feet)

U.S. loses bid to end children's climate change lawsuit

By a 3-0 vote, the 9th U.S. Circuit Court of Appeals said the government fell short of the “high bar” needed to dismiss the Oregon case, originally brought in 2015 against the administration of President Barack Obama.

Twenty-one children and young adults, ages 11 to 22, accused federal officials and oil industry executives of violating their due process rights by knowing for decades that carbon pollution poisons the environment, but doing nothing about it.

The government contended that letting the case proceed would be too burdensome, unconstitutionally pit the courts against the executive branch, and require improper “agency decision-making” by forcing officials to answer questions about climate change.

But the appeals court said the issues raised “are better addressed through the ordinary course of litigation.”

A trial is scheduled for Oct. 29 in the federal court in Eugene, Oregon.

President Donald Trump’s administration also has asked the U.S. Supreme Court to dismiss the lawsuit or put it on hold, and is awaiting a ruling. Its earlier bid to end the lawsuit failed in March.

Why Octopuses Could Never Disappoint 

These cephalopods, who telegraph their moods by color changes and solve problems by using tools, have surprised me again and again.

And now it’s happened again. An octopus has astonished me.

This time, it’s a common octopus caught on camera in South African waters by a dive team for the documentary Blue Planet II, currently airing on BBC America in the United States.

The action is dramatic. A pyjama shark seizes the octopus. Just as the situation begins to look dire, the octopus stuffs the shark’s gills shut using its sinuous arms, making it impossible for the shark to breathe — until the shark releases it.

Not every creature in the ocean is cute and cuddly – some are downright spooky!

Semana Santa

Tortuguero

Puerto Viejo

Beach

Other exchange students

This past week was Semana Santa, so in other words, it was spring break for us. Everyone in our program (there are 14 IFSA students in Costa Rica for the semester and two more that are in their second semester here) had travel plans. A few people went to places alone, one group traveled outside of Costa Rica, and I went with a group to Tortuguero and Puerto Viejo. There were six of us total, and the initial trip to Tortuguero lasted half a day.  

It concluded with a one hour boat ride to Tortuguero, which speaks to how secluded and isolated it is. The main road is a large sidewalk and there were no cars. The beach was never crowded, although the ocean was too rough to swim in. After a few days, I recognized people as we walked around the town. Tuesday morning, I unfortunately woke up with a headache due to a lack of food the day before. So I missed the beach day by trying to sleep it off, but after lunch, everyone else wanted to take a nap. Since I was feeling better, I decided to go to the beach alone (which was less than five minutes from the hotel- and it took less than 10 minutes to get from one shoreline to the other). It was so relaxing since there were not many people and at one point, a dog decided to hang out with me for five minutes. On Wednesday, we went on a canoe tour in el Parque Nacional de Tortuguero. We saw lots of birds and a two different points, we were a few feet away from caimans.  

We left Tortuguero Thursday morning and spent half the day traveling to Puerto Viejo. Puerto Viejo was basically the opposite of Tortuguero as far as tourist destinations go. Tortuguero was secluded, very little people (even though there were tourists), no cars. Puerto Viejo was crowded and is a popular destination for Semana Santa. And while I think the beach in Tortuguero was more beautiful than any in Puerto Viejo, the ocean was nicer in Puerto Viejo because it was relatively easy to find a good place to swim.  

Now, going into the trip, I thought that our group was probably relatively cohesive. But as in all groups (even small ones) there were tensions that slowly got worse as the week went on. First, let me give a little context. Out of the 14 of us, there are very clear tensions in the group. It is easy to tell who does not get along with someone else. Lines and groups formed relatively quickly since we spent so much time together in the beginning. But for Semana Santa, it seemed that the two main groups had divided. However, even within ours, there was tension. It was mainly little stuff that slowly increased as the week went on, but the important thing is that it did not prevent anyone from enjoying themselves on the trip.  

This is also kind of a teachable moment as well. Some people think that when they go abroad, they will meet and become great friends with awesome people. While this is not necessarily wrong, I think it is important to realize that just because you are abroad, it doesn't mean that people will leave stuff that leads to social problems and tensions in the U.S. My advice? Don't force friendships, especially if you don't make friends right away anyways, like me. Be yourself and focus on enjoying your time during this awesome experience. Chances are you will develop friendships and they will be natural ones since you have not forced anything (this is what I have done, and I have become friends with other IFSA students). And if you don’t, that's okay too. Remember, you only have a few months to take in as much of another country as possible and that may mean you don't have enough time to develop very strong friendships. And instead of trying to build friendships with other exchange students, try to build relationships with your host family and with native students. They are the ones who can really show you what their country has to offer.

DISCOVERING THE GIANTS OF THE DEEP: BATHYNOMUS JAMESI

A newly discovered species of giant isopod, Bathynomus vaderi, has recently been described from the deep waters around Spratly Islands, off Vietnam. The species, named after the infamous Sith Lord, Darth Vader, due to the striking resemblance of its helmet-like head, adds to the growing diversity of the Bathynomus genus. Bathynomus vaderi is characterized by several unique features, including a parallel-margin clypeal region, a raised dorsal surface on its pleotelson, and upwardly curved pleotelson spines.

Giant isopods like Bathynomus vaderi have become an expensive delicacy in Vietnam. Until 2017, local fishermen only sold them as an incidental product at low prices, but in recent years the media has drawn the public's attention to this unusual seafood. Some even claim that it is more delicious than lobster, the "king of seafood." This new species is described from several individual found at seafood markets in Hanoi, Vietnam.

In Vietnam, Bathynomus species, are often referred to as "sea bugs". Their unique appearance and large size make them a delicacy, and they can command high prices, with larger individuals of B. vaderi reaching up to 2 kg. In recent years, demand for these creatures has risen, especially in urban centers like Hanoi and Hồ Chí Minh City, where they are displayed in restaurants and sold through online seafood markets. This growing industry highlights the continued fascination with deep-sea species and the need for ongoing research to better understand their ecology and conservation.
