The ability to cling to things with tentacles is a unique feature found in a group of jellies called Olindiidae. They tend to hang out on rocks/aglae/anything comfy, and fish for food using their tentacles like fishing lines, reeling in their catches to munch on while vibing bsky.app/profile/rebe...

These lights are formed by biofluorescent proteins, which absorb light (probably UV) & shine it out as a continuous bright green. 🪼 Vallentinia adherens 📸 in ALT text, @inaturalist.bsky.social
![Rule 8: Commit to tidyverse or base R
In R, you can help new learners build a strong foundation by committing to either the Tidyverse ecosystem or base R from the outset. Switching between related languages or language “dialects” can erode learner confidence and cause confusion [21,34]. For example, learners often struggle with when to extract a column of a dataset as a vector using dplyr::pull(). Mixing in base $ notation further muddies the waters. A new programmer can accomplish their end goal using either readr::read_csv (Tidyverse) or read.csv() (base R) and does not need to know both when starting out.
The choice of R ecosystem depends both on your experience and comfort level, as well as the goals of your student audience. For example, our audience typically consists of researchers and practitioners in the public health sphere who have no prior R experience. These learners are more interested in data cleaning, analysis, and visualization. The Tidyverse works well for these goals and is valued by instructors for its readability, consistency, and user community [34]. However, if your learners are more interested in software development, dependency minimization, optimization, or mathematical applications, base R might be more appropriate. Some researchers have found base R easier for learners [35], while others found no difference [36].](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:c4uwzyiy4la35kq35rsft35z/bafkreiedgra4z3whqf6l4xslwju3g4lxzx7jxtrxym4354mhfc7456vwje)
