Hasta entonces, las crías dependen de esconderse en aguas poco profundas para no ser comidas por tiburones y orcas. Esto muestra que proteger los manglares y las costas es clave para que la especie sobreviva, algo que ya no es solo un asunto de biólogos marinos. Si las costas se degradan, la próxima generación de estas criaturas llega al mar abierto sin defensa.","quienFirma":"Universidad no especificada en la fuente (reportado por Phys.org)","confianza":"divulgacion","consulta":{"pregunta":"¿Qué tan importante es proteger las costas para la fauna marina?"}},"sello":{"hash":"531abfbbefe654ba2e817d9d59ac648d00b69d98977d2bceeb3a6e1561665c13","sello":"ff674be4ae0fe7ca1431f384bf00b8d8bb183af3382be433ad77582cb6b7fad7","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6573690,"aleatorio":"e4524d9fa2c8d6258c3902ed3b0ca19bed2e45a8efabc44b43e59222da8c45cd","tiempo":"2026-10-22T04:02:00.000Z"},"nist":{"cadena":2,"pulso":1994050,"salida":"0EA0DAFE8CB4305E28FAF1DD0F8FB8D11EB0054E82D48BF833A6E375923B8C71DE7CAABE525AA75BBF142B6A5FAB35A94B1D9DA64652AD4810FEE2DB0E4CC301","tiempo":"2026-10-22T04:01:00.000Z"},"noAntes":"2026-10-22T04:02:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 04:02:21 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Baby manta rays hunker down close to coasts before facing the open ocean's dangers","descripcion":"Giant manta rays can grow up to nine meters (30 feet) long with a disk size of seven meters (23 feet) across and weigh up to 2,000 kg (4,400 pounds). This size leaves them with very few natural enemies once they reach adulthood at around eight to 10 years old. But giant manta ray babies, called pups, cannot rely on their size to protect them from predators that live in the open ocean, including several species of shark and orcas.","pubDate":"Thu, 22 Oct 2026 00:00:01 EDT","url":"https://phys.org/news/2026-10-baby-manta-rays-hunker-coasts.html"},"indexado":"2026-10-22T04:01:55.849Z"}}
