Liongbun

Glaucostegus thouin, the clubnose guitarfish, is a large elasmobranch in the family Rhinobatidae native to the Indo-Pacific Ocean, ranging from the Red Sea and East African coast across the Indian Ocean to Southeast Asia and northern Australia. This ray reaches lengths of up to approximately 2.7 m and has the characteristic flattened body with a pronounced snout and pectoral fins that give the family its guitarfish name. Like other guitarfishes, it inhabits shallow coastal waters, estuaries, and sandy or muddy seabeds where it forages for benthic invertebrates and small fish. The clubnose guitarfish is listed as Critically Endangered by the IUCN due to severe population declines driven primarily by overfishing and bycatch in coastal fisheries across its range. Shallow-water elasmobranch species are particularly vulnerable to depletion because they are easily caught in inshore nets and have slow reproductive rates. The species has been assessed as having suffered extremely high population declines over recent decades, with significant range contractions documented across much of its former distribution. Effective fisheries management and marine protected areas in its core habitat are critical for its recovery.

common bottlenose dolphin

The most studied and recognized dolphin species, bottlenose dolphins inhabit warm and temperate oceans worldwide, from coastal shallows to the open sea. Highly intelligent with large brains relative to body size, they demonstrate self-recognition, complex communication, and social learning. They live in fluid fission-fusion societies and cooperate to herd fish. A keystone indicator species for marine ecosystem health.
