charring auh#Seaurchins or urchins (/ˈɜːrtʃɪnz/) are echinoderms in the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal zone to deep seas of 5,000 m
blastoise7229 at KillBaitHow Smashing Millions of Sea Urchins Revived California's Kelp Forests
Over the past two decades, a combination of pollution, overfishing, and a growing population of sea urchins has led to the dramatic decline of kelp forests along the California coast. Kelp ecosystems, known for being vital to marine biodiversity and carbon storage, have suffered severe degradation. ... [More info]
Lukas VFN 🇪🇺Discovery of #SeaStarWastingDisease cause sheds light on #kelp forest collapse and recovery https://phys.org/news/2025-07-discovery-sea-star-disease-kelp.html
"This comes more than a decade after the start of the marine epidemic that has killed billions of #SeaStars... The 4-year investigation eventually pinpointed the microbial culprit: a strain of the bacterium #Vibrio pectenicida... The loss of #SunflowerSeaStars, which support #KelpForests by feeding on kelp-eating #SeaUrchins, has had widespread and lasting effects on ecosystems"

"Climate change and human activity have impacts that ripple through all ecosystems. Their negative effects can lead to population imbalances across these various #ecosystems. While populations of many species are declining because they are unable to survive the rapid #EnvironmentalChanges, this is often not the case for venomous aquatic life like #SeaUrchins and jellyfish. In fact, these populations are increasing across the globe, with damaging effects on other living #AquaticOrganisms and human activity."

Halotis PourtalesClypeaster rosaceus (Linnaeus, 1758)
Le dollar des sables à rosace (Clypeaster rosaceus) est une espèce d’oursin irrégulier, présent dans l'océan atlantique tropical ouest.
C'est un oursin irrégulier aplati et allongé, dont l'anus a migré vers la périphérie de la face orale (inférieure) du test (coquille), pour former un « arrière ». Il mesure jusqu'à 13 cm de long pour4 cm d'épaisseur. Il est recouvert d'un dense tapis de fines radioles (piquants) de couleur rose-violacé, qui lui servent à progresser dans le sable. Les aires ambulacraires sont en forme de 5 gros pétales de deux rangées de pores, comme chez tous les Clypeasteroida. Les podia sont modifiés en branchies.
Cet oursin est un fouisseur : il filtre le sable pour se nourrir de matière organique.
On trouve cet oursin à faible profondeur sur les fonds sableux des Caraïbes, notamment auxAntilles.

But how slow or fast they grew back depended on the location—and until now, scientists didn't understand why".

Sea otters help kelp forests recover—but how fast depends on where they are
When sea otters were reintroduced along the coastlines of islands in Southern California and British Columbia, researchers saw kelp forests return to areas that were destroyed by sea urchins. But how slow or fast they grew back depended on the location—and until now, scientists didn't understand why.
