Dave the Diver Remaining Jungle Bosses: All 3 Explained

Dave the Diver remaining Jungle bosses keep getting named in the corners of other In the Jungle guides without ever getting a fight of their own: Stethacanthus, Xiphactinus, and Giant Snapping Turtle. A fourth name usually gets lumped in with them too. It shouldn't be. Basilosaurus shows up in the Lakebed Sea's creature collection right alongside the other three, but it doesn't have an actual boss fight attached to it, and that's worth correcting before it spreads any further.

TL;DR: Three confirmed dive bosses remain uncovered on this site: Stethacanthus, nicknamed the Ancient Shark (Lakebed Sea, weak points on the tail and underbelly, brown armor patches block damage), Xiphactinus (Lakebed Sea, confirmed real via gameplay footage but with no published HP or attack breakdown yet), and the Giant Snapping Turtle (Sunang Ruins in Lower Utara Lake, neck is the weak point, shotgun recommended). Basilosaurus appears in the same creature collection but has no actual fight, confirmed by a documented player account and its own in-game rank data.

Dave the Diver remaining Jungle bosses? (quick answer)

Stethacanthus, Xiphactinus, and the Giant Snapping Turtle are the three confirmed dive bosses in the In the Jungle DLC that haven't gotten a dedicated breakdown yet. Basilosaurus, often assumed to be a fourth, is a Lakebed Sea creature but not an actual fight.

Key takeaways

• Stethacanthus ("Ancient Shark") fights in an enclosed, pillar-lined room in the Lakebed Sea. Its brown body patches are armor that blocks damage outright; the tail and underbelly are the real targets.
• Xiphactinus is confirmed as a real fight via independent gameplay footage, but no guide site has published its HP or named attacks yet. Treat any specific number you see elsewhere as unverified.
• Giant Snapping Turtle waits in the Sunang Ruins, Lower Utara Lake, roughly 60 meters down. Its elongated neck is the weak point, and a shotgun's spread is the recommended tool.
• Basilosaurus is not a boss fight. It shares the same special creature-card numbering as the four real bosses, but its own rank data and a documented player account both confirm there's no combat encounter tied to it.
• No Steam patch since the DLC's June 18, 2026 launch has specifically altered any of these three fights, based on a full read of the game's official patch note history.
• Reddit has no discussion threads for any of the four names as of this writing, confirmed via both subreddit-restricted and sitewide searches.

Dave the Diver remaining Jungle bosses: where the names come from

Every Dave the Diver: In the Jungle creature has a card in the Marinca Bloom collection app, and the site's own wiki transcription of that card data settles the "is this real" question cleanly. Regular fish get card numbers in the 3000s. Five creatures get a separate block, numbers 3901 through 3905: Sulong, the Giant Snapping Turtle, Stethacanthus, Xiphactinus, and Basilosaurus. Four of those five carry a special Rank 99 tag that no ordinary fish uses. Basilosaurus doesn't. Its card shows Rank 9, the same tier as large-but-ordinary catches. That single data point lines up exactly with what a documented player account found in practice: four real fights, one creature that only looks like a fifth.

A frame from the DLC's official launch trailer showing the kind of dark, ruin-choked encounter these three fights take place in. Not a confirmed shot of any one specific boss.

Stethacanthus (350cm), Xiphactinus (600cm), and Basilosaurus (1500cm, the largest creature in the whole Lakebed Sea) are all catalogued in that zone. The Giant Snapping Turtle (600cm) is catalogued separately, under Lower Utara Lake, which matches where it actually spawns: the Sunang Ruins, not the Lakebed Sea proper. If you've read the Jungle DLC fish guide or the essential tips guide, you may have seen Basilosaurus grouped in with the zone's "three boss fights." That's the one claim on this site this article is correcting, based on the rank data and player-account evidence below.

Stethacanthus (Ancient Shark) boss guide

The Lakebed Sea's shark fight takes place in an enclosed room with stone pillars at the bottom, reached after the Advanced Purification Filter opens the zone. According to a guide published by games.gg writer Nuwel on June 23, 2026, the fight's core mechanic is armor management: the shark's brown body patches "deal zero damage" to projectiles that land on them, so staying below the shark and shooting up at its underbelly is the confirmed way to keep every shot counting. The tail is the other exposed target.

Its kit runs on two moves. A lunge bite where "the shark surges forward a short distance and tries to bite," and a drill spin where it "coils and launches itself across the screen in a spinning drill motion." The fight's real trick is baiting that drill attack into one of the room's stone pillars. A successful pillar hit stuns the shark and opens a mounting mini-game worth 200 damage per successful stab, by far the fastest damage window in the fight. After roughly 300 total damage, stalactites start dropping from the ceiling and the shark starts chaining drill attacks back to back, so the pillar-bait trick gets riskier to set up in the fight's second half.

Beating it lets you harvest Stethacanthus meat off the body, which sells at Bancho Grill. The same guide recommends listing only a few portions at a time rather than dumping the whole stock, since prices soften the more you sell in one sitting.

No exact HP total turned up in the search for this article, and the 300-damage phase-transition figure comes from a single source, not two independently agreeing accounts the way the Giant Fringehead numbers were. Treat it as the best available estimate, not a locked number.

Xiphactinus: confirmed real, not yet fully documented

This is the one fight on this list without a written strategy guide anywhere. games.gg's own Dave the Diver guide index doesn't list a Xiphactinus entry, and a site search for the name returns nothing. That's a real gap in existing coverage, not something this site skipped out of laziness.

What is confirmed: Xiphactinus is real. Two independent creators uploaded standalone gameplay footage of the fight in the days after launch, a "Xiphactinus Boss Fight" video from ChickenSoup (uploaded June 23, 2026) and a chapter inside Ben-Gun's full "All Bosses + Ending" compilation (uploaded June 18, 2026, 269,000+ views), which places the fight between Wild Boar and the DLC's actual final boss in the game's own progression order. Both accounts show a fight lasting roughly three minutes, in line with the other confirmed bosses on this list rather than a quick creature sighting. The Marinca Bloom card data puts it at 600cm and describes it, accurately, as a fish whose "powerful jaws tear apart anything in its path," matching the real-world Xiphactinus, a genuine Cretaceous-era predator known for an oversized mouth relative to its body.

What isn't confirmed: HP, named attacks, or a specific weak point. If you see a number attached to this fight elsewhere, treat it the same way this site treats any unsourced claim, as unverified until an actual strategy write-up backs it up. The honest approach for now is general Lakebed Sea prep rather than a fight-specific script: the zone's other creatures have had their attack patterns strengthened in a live patch before (Ophthalmosaurus and Hensodon both got tougher in the August 6, 2026 update), so going in geared for a real fight rather than an easy catch is the safer assumption.

Giant Snapping Turtle boss guide

The Giant Snapping Turtle lives in the Sunang Ruins, a sub-area of Lower Utara Lake roughly 60 meters down, its den entrance blocked by vines until you clear the prerequisite chain. Per the sibling staff guide and walkthrough on this site, the "A Monster Snapping Turtle!" sub mission unlocks after filling 50 entries in the Marinca Bloom app. The games.gg write-up adds the specific prep steps: talk to Basu and the village chief, then find Sato for the den's exact location, then bring a Level 2 or better pickaxe to mine Deep Sea Ore and upgrade your machete through blacksmith Perak before diving in.

The fight itself rewards a specific weapon choice. Nuwel's games.gg guide recommends a shotgun outright, since its pellet spread lands multiple hits on the turtle's neck, the fight's confirmed weak point, in a single shot rather than requiring repeated precise single-target hits.

Three moves make up its kit. The Neck Whip is, in the guide's own words, "the most dangerous move in the kit," and it swings both in front of and behind the turtle, so positioning on either side isn't automatically safe. The Head Slam is the opposite: a punishable mistake for the boss. "The moment the head connects with the ground, the Snapping Turtle is completely vulnerable for a few seconds," and swimming toward the ceiling as it rears back avoids the impact entirely, turning its riskiest-looking attack into the fight's best damage window. Once it's taken enough damage, it retreats into its shell and spins, a defensive phase you dodge by tracking its spin trajectory and moving up or down to stay clear. Grapple points on the ceiling help with repositioning specifically during the Neck Whip's wide arc.

Winning gets you more than a kill. Speaking to Sato afterward unlocks him as hireable Bancho Grill staff, and per the Jungle Gun guide on this site, clearing the full quest chain also opens the turtle's arena to Fire Eel spawns, a farmable source for a rifle-path upgrade material, resettable by surfacing and diving back in. No HP total is documented for this fight either.

Step-by-step: Dave the Diver remaining Jungle bosses prep checklist

1. Confirm your Purification Filter tier. The Lakebed Sea (Stethacanthus, Xiphactinus) needs the Advanced Purification Filter; the Sunang Ruins sit inside Lower Utara Lake, which only needs the base filter, but a Level 2+ pickaxe is a separate, additional requirement for the turtle specifically.
2. Gear check before Stethacanthus. Bring a weapon you can angle upward with, since the confirmed strategy depends on staying below the shark to hit its underbelly rather than its armored back.
3. Don't skip Perak's machete upgrade before attempting the Giant Snapping Turtle. It's a named prerequisite in the only detailed guide available for this fight, not an optional convenience.
4. Bring a shotgun for the turtle fight specifically. The neck weak point rewards spread damage over single-target precision.
5. Go into Xiphactinus expecting a real fight, not a quick catch. With no published breakdown, prepare general-purpose gear rather than a fight-specific loadout you can't verify yet.
6. Don't go looking for a Basilosaurus fight. If your game doesn't trigger one, that's expected, not a bug on your end.

Tips for the Lakebed Sea and Sunang Ruins bosses

Treat the pillar-bait trick as this fight's real damage source

Stethacanthus's mounting mini-game after a pillar stun deals more per opening than chipping away with regular shots. Prioritize positioning for that bait over trading hits directly.

The turtle's scariest move is its safest punish

New players tend to panic-dodge the Head Slam. Swimming up into it is the correct read, and it's the single biggest free damage window in the fight.

Sell boss meat in small batches

Both Stethacanthus meat and other boss drops soften in sale price the more you unload at once at Bancho Grill. Spread sales across a few in-game days if you're farming for Doni.

Watch for balance patches before trusting an old write-up

The Lakebed Sea has already seen one live balance change (the August 6, 2026 patch strengthened Ophthalmosaurus and Hensodon specifically). None of the three bosses here have been touched yet, but that could change, and a strategy that worked pre-patch isn't guaranteed to hold afterward.

Common mistakes

• Assuming Basilosaurus has a fight to find. It doesn't, based on the evidence above. Don't burn time looking for a trigger that isn't there.
• Shooting Stethacanthus's armored back. Those brown patches block damage outright. Reposition below it instead.
• Attempting the Giant Snapping Turtle without the pickaxe and machete prerequisites. The den itself is gated behind gear you have to prepare in advance, not something you stumble into unequipped.
• Dodging the turtle's Head Slam instead of using it. That's the fight's best damage window, not a threat to avoid.
• Trusting an unsourced HP number for Xiphactinus. No guide site has published one as of this writing; anything you see claiming otherwise should be treated skeptically until it cites a source.

Frequently Asked Questions

How many bosses are left uncovered in Dave the Diver's Jungle DLC? Three confirmed dive bosses beyond Murau Temple and Sulong: Stethacanthus (Ancient Shark), Xiphactinus, and the Giant Snapping Turtle. A fourth commonly assumed boss, Basilosaurus, does not have an actual fight.

Is Basilosaurus a real boss fight in Dave the Diver In the Jungle? No. It appears in the Lakebed Sea creature collection alongside the real bosses, but a documented player account confirms there's no combat encounter attached to it, just a brief, non-combat sighting.

What is the Ancient Shark's weak point in Dave the Diver? Its tail and underbelly. Brown armor patches on its body block damage outright, so staying below the shark to shoot upward is the confirmed way to avoid wasting shots on the armored zones.

Where do you fight the Giant Snapping Turtle in Dave the Diver: In the Jungle? In Lower Utara Lake's Sunang Ruins, roughly 60 meters down. The den entrance is blocked by vines, and reaching it requires a Level 2+ pickaxe, mined Deep Sea Ore, and an upgraded machete from Perak.

What weapon works best against the Giant Snapping Turtle? A shotgun. Its spread lands multiple pellets on the turtle's elongated neck, its confirmed weak point, in a single shot, which is faster than relying on a single-target weapon.

Does Xiphactinus have a documented HP value or attack pattern breakdown? Not yet from any accessible guide site. Its existence and location in the Lakebed Sea are confirmed via game data and independent gameplay footage, but nobody has published exact numbers or named attacks so far.

What do you get for beating the Giant Snapping Turtle? After the fight, speaking to Sato unlocks him as a hireable Bancho Grill staff member. Clearing the quest chain also opens up Fire Eel farming inside the turtle's arena for a Jungle Gun upgrade material.
