Macro
Nudibranchs
Nudibranchia · Marine gastropod mollusks — order Nudibranchia; order-level overview of more than 3,000 described species
Nudibranchs are the reason macro divers stop covering distance. More than three thousand described species of these shell-less snails crawl the world's seafloors wearing colors that work as warnings, advertisements, and camouflage all at once — and more are named every year, with muck hotspots regularly producing animals new to science. The order splits broadly in two: dorids, carrying a rosette of gills on the back, many recycling sponge toxins into chemical defense; and aeolids, fringed in tentacle-like cerata that store working stinging cells stolen from the hydroids they eat. Rhinophores, the paired head antennae, smell the water for prey and mates. Most species live weeks to a year, so casts turn over fast and no two months on the same site produce the same list. Slow to a crawl and the sand starts producing.

"상주종"은 해당 다이빙 포인트에서 대부분의 다이빙 시 만날 수 있다는 의미이며, "계절종"은 표기된 월에 안정적으로 출현한다는 뜻입니다. 그 외의 생물은 보너스로 여기세요 — 계획의 근거로 삼지 마세요.

한눈에 보는 최적의 달
이해하기
서식지: Every bottom type divers visit — reef, rubble, sand, kelp, jetty piles, mud — wherever each species' prey grows; the order as a whole ranges from tide pools to the deep sea.
범위: All oceans, polar to tropical; the Coral Triangle holds the richest shallow-water diversity known.
행동 특성: Slow, chemically defended browsers; hermaphrodites that mate side by side and lay coiled egg ribbons. Aeolid species store working stinging cells from the hydroids they eat.
먹이: Specialists almost to a species: sponges, hydroids, bryozoans, tunicates, anemones, eggs, or other sea slugs.
크기: 보통 0.03 m; 최대 기록 수심 0.6 m (order-wide range; most diver-found species are 1–6 cm, while the Spanish dancer reaches about 60 cm).
이 생물 주변에서의 행동 요령
Shoot without touching or relocating — posed slugs on borrowed backgrounds are the macro world's staged wildlife problem. Keep strobe sessions short per animal.
보존
Almost none have been evaluated for the IUCN Red List; their fortunes track the sponges, hydroids, and other prey they depend on.
