These little guys spawn throughout the ocean map, and you’ll need to collect them all to fill the town’s museum. Take a look at this sea critter’s guide to start your own rockin’ crustacean band.

Where to Find Sea Critters in Coral Island – A Complete Guide

There are nine major areas in the ocean where sea critters can spawn. There are also specific depths to some of the regions. If a critter you want to find isn’t showing up in a particular area, you may need to travel deeper into the ocean to find them.

Some of these areas also aren’t accessible until you complete specific diving quests.

Take a look at the different areas and the sea critters that spawn there.

1. Natural Area

The Natural Area is the initial part of the ocean where you spawn after diving for the first time. It encompasses a vast area that you need to heal with orbs. You’ll need to find these orbs to progress into the other regions.

Critter:	Time:	Rarity:
Arrow Crab	Night	Common
Common Starfish	All Day	Common
Blue Lobster	Night	Rare
Sea Slug	All Day	Uncommon
Yeti Crab	Night	Common

One of the best sea critters that spawn in this area is the Blue Lobster. It’s a rare critter that only appears at night.

2. Orchestra Area

There are a few regions in the ocean called the Orchestra area. You’ll need to head east to access both of them. There are also Orchestra areas deeper in the ocean, too. So, if the critter you’re looking for isn’t in the shallow part of the ocean, then head in deeper.

Critter:	Time:	Rarity:
Arrow Crab	Night	Common
Flowerhat Jellyfish	Night	Uncommon
Jayakar’s Seahorse	All Day	Common
Whelk	All Day	Common
Giraffe Seahorse	All Day	Common
Pom-pom Crab	All Day	Uncommon
Sea Slug	All Day	Uncommon
Venus’s Flower Basket	All Day	Super Rare
Pink Meanie Jellyfish	All Day	Super Rare
Atolla Jellyfish	All Day	Rare
Cauliflower Jellyfish	All Day	Uncommon
Harlequin Shrimp	Night	Uncommon
Brisingida Starfish	All Day	Uncommon
Red Knob Starfish	All Day	Uncommon
Sea Anemone	All Day	Common
Yeti Crab	Night	Common

Two sea critters that spawn in the Orchestra area are super rare. The Venus’s Flower Basket and Pink Meanie Jellyfish spawn in the deeper parts of the Orchestra area. They’re both around all day.

3. Mid Area

Like the Orchestra area, the Mid area has a few more deeper sections in the ocean. You’ll need to meet with the Merfolk before being able to explore the area. Although there aren’t any super rare critters in the region, it does have some rare ones.

Critter:	Time:	Rarity:
Arrow Crab	Night	Common
Flowerhat Jellyfish	Night	Uncommon
Jayakar’s Seahorse	All Day	Common
Eight-Armed Starfish	Day	Uncommon
Giraffe Seahorse	All Day	Common
Hermit Crab	All Day	Common
Mauve Stinger Jellyfish	Night	Common
Cannonball Jellyfish	All Day	Common
Upside-down Jellyfish	Day	Common
White-spotted Jellyfish	Night	Common
Blue Crab	Night	Uncommon
Sexy Shrimp	Day	Common
Harlequin Shrimp	Night	Uncommon
Crown-of-Thorns Starfish	All Day	Rare
Blue Starfish	Night	Common
Giant Isopod	Day	Rare
Ruby Seadragon	Day	Rare
Stone Crab	Night	Common

The Crown-of-Thorns Starfish, Giant Isopod, and Ruby Seadragon are rare critters that call this place home. Thankfully, they all spawn during the day so that you can keep an eye out for them simultaneously.

4. Jellyfish Area

The Jellyfish area is north of the Natural area, so head northward from the starting region. As its name suggests, there are plenty of jellyfish that spawn here.

Critter:	Time:	Rarity:
Common Starfish	All Day	Common
Tigertail Seahorse	Night	Common
Mauve Stinger Jellyfish	Night	Common
Cannonball Jellyfish	All Day	Common
Upside-down Jellyfish	Day	Common

All the critters here are common, though, so you’ll encounter average fish–but a lot of them.

5. Seahorse Area

The Seahorse area resides in the southern part of the diving map. It sits between the two Herding areas. Much like the Jellyfish area, you can find plenty of seahorses in the Seahorse region. Other critters spawn, too, though.

Critter:	Time:	Rarity:
Flowerhat Jellyfish	Night	Uncommon
Jayakar’s Seahorse	All Day	Common
Whelk	All Day	Common
Ruby Seadragon	Day	Rare

Keep an eye out for the Ruby Seadragon that calls this area its home. It’s a rare critter that spawns during the day.

6. Herding Area

There are several different Herding areas on the map. Some are near the shallow part of the ocean, while others are deeper. Despite covering a bit of the map, the Herding area doesn’t have too many fish that spawn in it.

Critter:	Time:	Rarity:
Tigertail Seahorse	Night	Common
Skunk Cleaner Shrimp	All Day	Common
Eight-Armed Starfish	Day	Uncommon
Mantis Shrimp	All Day	Rare
Blue Lobster	Night	Rare
Hermit Crab	All Day	Common
Pom-pom Crab	All Day	Uncommon
White-spotted Jellyfish	Night	Common
Brisingida Starfish	All Day	Uncommon
Yeti Crab	Night	Common

Watch out for Mantis Shrimp and Blue Lobster, rare spawns in this area. While the Mantis Shrimp spawns all day, you’ll only find the Blue Lobster at night.

7. Kelp Forest Area

You’ll discover the Kelp Forest area just before you head into the city belonging to the mermaids. You might think many fish would spawn near a food source, but that isn’t the case. Only a few critters spawn in this area.

Critter:	Time:	Rarity:
Skunk Cleaner Shrimp	All Day	Common
Whelk	All Day	Common
Hermit Crab	All Day	Common
Calico Lobster	Night	Super Rare

The best critter to hunt for here is the Calico Lobster. It’s a super rare critter that only spawns at night.

8. Yoga Retreat Area

Once you advance past the mermaid area, you enter the deeper parts of the ocean. You have a curfew in this deep region, so finding critters that spawn at night can be challenging. Like the Kelp Forest region, the Yoga Retreat area has fewer critters spawning.

Critter:	Time:	Rarity:
Giraffe Seahorse	All Day	Common
Atolla Jellyfish	All Day	Rare
Split-Colored Lobster	Night	Super Rare
Hedgehog Seahorse	All Day	Uncommon

You’ll want to find another type of lobster in this area. The Split-Colored Lobster is a rare critter that comes out during the night.

9. Unnamed Area

The last area is the furthest from the starting area in the ocean. You’ll have to heal a lot of coral and advance through the ocean to reach this mysterious part of the ocean. It’s worth reaching, however, because there are many rare critters here.

Critter:	Time:	Rarity:
Bloodbelly comb Jellyfish	All Day	Uncommon
Cauliflower Jellyfish	All Day	Uncommon
Horseshoe Crab	Night	Common
Blue Crab	Night	Uncommon
Sexy Shrimp	Day	Common
Cotton Candy Lobster	Night	Legendary
Sunflower Sea Star	All Day	Uncommon
Crown-of-Thorns Starfish	All Day	Rare
Red Knob Starfish	All Day	Uncommon
Blue Starfish	Night	Common
Leafy Seadragon	Day	Super Rare
Hedgehog Seahorse	All Day	Uncommon
Shiho’s Seahorse	All Day	Rare

The only two legendary critters also make their home in this region. The Cotton Candy Lobster and the Chambered Nautilus both reside here. You’ll find the Cotton Candy Lobster at night, while the Chambered Nautilus prefers to come out during the day.
