What type of shark is able to hold their heads up out of the water?
All epaulette sharks are known to walk across the reef and seafloor, but it is Hemiscyllium ocellatum (most commonly called the epaulette shark) that has been most widely studied for its ability to walk outside of the water.
Can great white sharks see above water?
Light is defused, acuity reduced and sensitivity increased. Such an adaptation enables sharks to see even in low light and dark murky water up to 10 times greater than humans. Also unlike humans, shark eyelids serve to protect the eye when attacking prey.
Can Sharks see out of water?
SIGHT. Light doesn’t travel well through water. So sharks need to maximise the amount available to help them see. With eyes positioned on the side of their head they’re able to see in almost all directions.
What does a remora do for a shark?
The remora receives more than a convenient food source; the sharks protect them from predators and give them free transportation throughout the oceans. Remoras keep the waters clear of scraps around the shark, preventing the development of unhealthy organisms near the shark.
What is the fish that sticks to sharks?
remora
What kind of fish cleans sharks?

What has a pH of 1?
The pH scale
| Increasing pH (Decreasing Acidity) | Substances |
|---|---|
| 0 (most acidic) | Hydrochloric acid (HCl) |
| 1 | Stomach acid |
| 2 | Lemon juice |
| 3 | Cola, beer, vinegar |
Is pH 10 a strong base?
The pH of a weak base falls somewhere between 7 and 10. While strong bases release hydroxide ions via dissociation, weak bases generate hydroxide ions by reacting with water.
What is the most basic substance?
Basic substances include things like baking soda, soap, and bleach. Distilled water is a neutral substance.
Which is weakest acid?
Hydrofluoric acid is the only weak acid produced by a reaction between hydrogen and halogen (HF). Acetic acid (CH3COOH), which is contained in vinegar, and oxalic acid (H2C2O4), which is present in some vegetables, are examples of weak acids.
Which is most strongest base?
The title of strongest base in the world belongs to ortho-diethynylbenzene dianion. This superbase has the strongest proton affinity ever calculated (1843 kJ mol−1), beating out a long-standing contender known as lithium monoxide anion.
What are the 7 strong bases?
Strong Arrhenius Bases
- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Barium hydroxide (Ba(OH)2)
- Caesium hydroxide (CsOH)
- Strontium hydroxide (Sr(OH)2)
- Calcium hydroxide (Ca(OH)2)
- Lithium hydroxide (LiOH)
- Rubidium hydroxide (RbOH)
Who is the king of base?
Answer: NaOH is the king of base. It is the strongest base.
