Essential recommendations to be great diver

 1. Learn how to breathe.

This is a little bit of a difficult suggestion, as a person on the significant rules of scuba diving is always to hardly ever hold your breath.
Breathe in a natural way. It may seem counterintuitive, but the much more you concentrate on how you might be respiratory, the speedier you will use your air. The simplest way is concentrating focus on what you see and doing in water rather then focus on respiration. You are SCUBA diving, love the experience!


Since you might be maintaining neutrally buoyant , you control your breathing .It is alright to concentrate in your respiratory sometimes for this objective.
In underwater ,  its not recomended to hold your breath for more than a second or two. This dangers each lung overexpansion accidents (i.e. popping like a balloon), and messing along with your blood CO2 concentrations.

Cat Fish


All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bonified leading spine-like ray on their dorsal and pectoral fins. As a defense, these spines may be locked into place so that they stick outwards, which can inflict severe wounds.In several species catfish can use these fin rays to deliver a stinging protein if the fish is irritated.This venom is produced byglandular cells in the epidermal tissue covering the spines.In members of the family Plotosidae, and of the genus Heteropneustes, this protein is so strong it may hospitalize humans, those unfortunate enough to receive a sting; in Plotosus lineatus, the stings may result in death.



Cat fish injuries
severe pain, tissue swelling and redness , muscle spasm and respiratory distress may occur

Sying Ray




Most stingrays have several barbed stingers (changed from dermal denticles) on the tail, which can be used exclusively in personal-defense. The stinger may possibly reach a approximately 35 cm (14 in), as well as its underside has two lines with venom glands.The stinger is covered having a slim covering of pores and skin, the integumentary sheath, in which the venom is focused.

Stingrays will not vigorously invasion mankind, even though stings do typically take place when a ray is inadvertently stepped on.To avoid moving on a stingray in shallow drinking water, the water needs to be waded via by using a shuffle.Otherwise, prior to wading, rocks might be cast into the drinking water to scare stingrays away.Experience of the stinger leads to local stress (from the lower by itselfswelling, ) and pain muscle mass pains from your venom, and then may result in disease from harmful bacteria or fungus infection.The damage is extremely painful, but seldom daily life-harmful unless the stinger pierces a crucial region.The barb generally breaks away from the injury, and surgical procedure may be needed to eliminate the fragments.

Can happen, infamously including Steve Irwin, though fatal stings are very rare. In this case, the stinger penetrated the thoracic wall surface, resulting in substantial trauma.
