Sea anemone study shows how #animals stay ‘in shape’
Scientists have shown how regenerating #SeaAnemones restore their shape following a major injury

Some animals, such as the starlet sea anemone, can regenerate large parts of their body, even after major injuries. EMBL researchers have shown this regeneration response involves cells and molecules in body parts far from the injury site and is directed towards restoring the animal’s original shape. The study sheds new light on the fundamental importance of maintaining body shape in animals and enhances our understanding of the molecular pathways involved in regeneration.

From #ctenophores to #scyphozoans: parasitic spillover of a burrowing sea anemone https://www.nature.com/articles/s41598-024-72168-7
"Some #SeaAnemones have developed a unique way to overcome the challenges of ocean dispersal. These anemones parasitize jelly-like marine #animals called #CombJellies to spread more easily through the #ocean... This study has uncovered the first documented cases of parasitic anemone planulae in true jellyfish"
Many marine organisms, like sea anemones, struggle to spread across the ocean, especially if they lack long, mobile larval stages. Unlike their jellyfish relatives, sea anemones do not have a medusa stage, making their dispersal challenging. Their only mobile stage is a tiny larva called a planula.

"For at least the three #anemone species I show here, when the males release sperm into the water column, the females do NOT release their eggs into the water. Instead, fertilization is internal. The embryos are protected as they develop in their mother’s hollow tentacles for around 2 weeks. Then, out into the ocean they swim as #plankton, via their mother’s mouth."

#Hermitcrabs are highly adaptable to their environment, even using #seaanemones as bodyguards.
And if there's a shortage of shells? It seems they don't mind settling into plastic cups.
Let's cherish nature and resources, shall we? ♻️

また貝殻不足なら？プラスチックのカップに住むことも厭わないようです
自然や資源を大切にしたいですね♻️

Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish
https://phys.org/news/2024-03-scientists-reveal-lineages-giant-sea.html
Anemonefish are better taxonomists than humans https://www.cell.com/current-biology/fulltext/S0960-9822(23)00990-9
"The scientists discovered that #anemonefish are better at distinguishing different populations of giant #SeaAnemones than humans. Through one or more sensory organs, these #fish identify a particular species of giant sea anemone to make their home and avoid other species."
Anemonefish form mutualistic relationships with the sea anemones they live in and these associations are not random: some species such as the yellow-tail anemonefish (Amphiprion clarkii) are generalists and can live in almost any sea anemone, others like the tomato clownfish (Amphiprion frenatus) are specialists, living in only one sea anemone species, the bubble-tip sea anemone (Entacmaea quadricolor). Reasons for these preferences are unclear because we know very little about the genetic diversity of giant sea anemones.
